-This patch adds DMA capabilities to the spi-qup driver. If DMA channels are
-present, the QUP will use DMA instead of block mode for transfers to/from SPI
-peripherals for transactions larger than the length of a block.

-
-This patch fixes a number of errors with the QUP block transfer mode. Errors
-manifested themselves as input underruns, output overruns, and timed out
-transactions.
-
-The block mode does not require the priming that occurs in FIFO mode. At the
-moment that the QUP is placed into the RUN state, the QUP will immediately raise
-an interrupt if the request is a write. Therefore, there is no need to prime
-the pump.
-
-In addition, the block transfers require that whole blocks of data are
-read/written at a time. The last block of data that completes a transaction may
-contain less than a full blocks worth of data.
-
-Each block of data results in an input/output service interrupt accompanied with
-a input/output block flag set. Additional block reads/writes require clearing
-of the service flag. It is ok to check for additional blocks of data in the
-ISR, but you have to ack every block you transfer. Imbalanced acks result in
-early return from complete transactions with pending interrupts that still have
-to be ack'd. The next transaction can be affected by these interrupts.
-Transactions are deemed complete when the MAX_INPUT or MAX_OUTPUT flag are set.
-
-Changes from v2:
-- Added in additional completion check so that transaction done is not
- prematurely signaled.
-- Fixed various review comments.
-
-Changes from v1:
-- Split out read/write block function.
-- Removed extraneous checks for transfer length
-
-Signed-off-by: Andy Gross <agross@codeaurora.org>

-Subject: [PATCH] spi: qup: Ensure done detection
-
-This patch fixes an issue where a SPI transaction has completed, but the done
-condition is missed. This occurs because at the time of interrupt the
-MAX_INPUT_DONE_FLAG is not asserted. However, in the process of reading blocks
-of data from the FIFO, the last portion of data comes in.
-
-The opflags read at the beginning of the irq handler no longer matches the
-current opflag state. To get around this condition, the block read function
-should update the opflags so that done detection is correct after the return.
-

-Subject: [PATCH 1/3] watchdog: qcom: use timer devicetree binding
-
-MSM watchdog configuration happens in the same register block as the
-timer, so we'll use the same binding as the existing timer.
-
-The qcom-wdt will now be probed when devicetree has an entry compatible
-with "qcom,kpss-timer" or "qcom-scss-timer".

-Subject: [PATCH] hwspinlock/core: add device tree support
-
-This patch adds a new OF-friendly API of_hwspin_lock_get_id()
-for hwspinlock clients to use/request locks from a hwspinlock
-device instantiated through a device-tree blob. This new API
-can be used by hwspinlock clients to get the id for a specific
-lock using the phandle + args specifier, so that it can be
-requested using the available hwspin_lock_request_specific()
-API.

-msb of the regmap_field was mistakenly given the value 32, to set all bits

-+ * The Qualcomm shared memory system is a allocate only heap structure that
-+ * consists of one of more memory areas that can be accessed by the processors
-+ * in the SoC.
-+ *
-+ * All systems contains a global heap, accessible by all processors in the SoC,
-+ * with a table of contents data structure (@smem_header) at the beginning of
-+ * the main shared memory block.
-+ *
-+ * The global header contains metadata for allocations as well as a fixed list
-+ * of 512 entries (@smem_global_entry) that can be initialized to reference
-+ * parts of the shared memory space.
-+ *
-+ *
-+ * In addition to this global heap a set of "private" heaps can be set up at
-+ * boot time with access restrictions so that only certain processor pairs can
-+ * access the data.
-+ *
-+ * These partitions are referenced from an optional partition table
-+ * (@smem_ptable), that is found 4kB from the end of the main smem region. The
-+ * partition table entries (@smem_ptable_entry) lists the involved processors
-+ * (or hosts) and their location in the main shared memory region.
-+ *
-+ * Each partition starts with a header (@smem_partition_header) that identifies
-+ * the partition and holds properties for the two internal memory regions. The
-+ * two regions are cached and non-cached memory respectively. Each region
-+ * contain a link list of allocation headers (@smem_private_entry) followed by
-+ * their data.
-+ *
-+ * Items in the non-cached region are allocated from the start of the partition
-+ * while items in the cached region are allocated from the end. The free area
-+ * is hence the region between the cached and non-cached offsets.
-+ *
-+ *
-+ * To synchronize allocations in the shared memory heaps a remote spinlock must
-+ * be held - currently lock number 3 of the sfpb or tcsr is used for this on all
-+ * platforms.

-
-SMEM is used on IPQ806x to store various board related information such
-as boot device and flash partition layout. We'll declare it as a device
-so we can make use of it thanks to the new SMEM soc driver.

-Subject: [PATCH 3/3] mtd: add SMEM parser for QCOM platforms
-
-On QCOM platforms using MTD devices storage (such as IPQ806x), SMEM is
-used to store partition layout. This new parser can now be used to read
-SMEM and use it to register an MTD layout according to its content.

-Subject: [PATCH 9/9] ARM: qcom: automatically select PCI_DOMAINS if PCI is
- enabled
-
-If multiple PCIe devices are present in the system, the kernel will
-panic at boot time when trying to scan the PCI buses. This happens on
-IPQ806x based platforms, which has 3 PCIe ports.
-
-Enabling this option allows the kernel to assign the pci-domains
-according to the device-tree content. This allows multiple PCIe
-controllers to coexist in the system.
-

-Subject: [PATCH] mfd: qcom-rpm: Driver for the Qualcomm RPM
-
-Driver for the Resource Power Manager (RPM) found in Qualcomm 8660, 8960
-and 8064 based devices. The driver exposes resources that child drivers
-can operate on; to implementing regulator, clock and bus frequency
-drivers.

-Date: Thu, 26 Mar 2015 11:29:26 -0700
-Subject: [PATCH] mfd: qcom_rpm: Add support for IPQ8064
-
-The IPQ8064 also includes an RPM following the same message structure as
-other chips. In addition, it supports a few new resource types to
-support the NSS fabric clocks and the SMB208/SMB209 regulators found on
-the reference boards.

-+Qualcomm Resource Power Manager (RPM)
-+
-+This driver is used to interface with the Resource Power Manager (RPM) found in
-+various Qualcomm platforms. The RPM allows each component in the system to vote
-+for state of the system resources, such as clocks, regulators and bus
-+frequencies.
-+
-+- compatible:
-+ Usage: required
-+ Value type: <string>
-+ Definition: must be one of:
-+ "qcom,rpm-apq8064"
-+ "qcom,rpm-msm8660"
-+ "qcom,rpm-msm8960"
-+
-+- reg:
-+ Usage: required
-+ Value type: <prop-encoded-array>
-+ Definition: base address and size of the RPM's message ram
-+
-+- interrupts:
-+ Usage: required
-+ Value type: <prop-encoded-array>
-+ Definition: three entries specifying the RPM's:
-+ 1. acknowledgement interrupt
-+ 2. error interrupt
-+ 3. wakeup interrupt
-+
-+- interrupt-names:
-+ Usage: required
-+ Value type: <string-array>
-+ Definition: must be the three strings "ack", "err" and "wakeup", in order
-+
-+- #address-cells:
-+ Usage: required
-+ Value type: <u32>
-+ Definition: must be 1
-+
-+- #size-cells:
-+ Usage: required
-+ Value type: <u32>
-+ Definition: must be 0
-+
-+- qcom,ipc:
-+ Usage: required
-+ Value type: <prop-encoded-array>
-+
-+ Definition: three entries specifying the outgoing ipc bit used for
-+ signaling the RPM:
-+ - phandle to a syscon node representing the apcs registers
-+ - u32 representing offset to the register within the syscon
-+ - u32 representing the ipc bit within the register

-Subject: [PATCH] regulator: qcom-rpm: Add missing state flag in call to RPM
-
-This adds the missing state parameter to the call down to the RPM. This
-is currently hard coded to the active state, as that's all we're
-supporting at this moment.

-Subject: [PATCH] clk_mux: Fix set_parent doing the wrong thing when INDEX_BIT
- && index >= 3
-
-If CLK_MUX_INDEX_BIT is set, then each bit turns on / off a single parent,
-so theoretically multiple parents could be enabled at the same time, but in
-practice only one bit should ever be 1. So to select parent 0, set
-the register (*) to 0x01, to select parent 1 set it 0x02, parent 2, 0x04,
-parent 3, 0x08, etc.
-
-But the current code does:
-
- if (mux->flags & CLK_MUX_INDEX_BIT)
- index = (1 << ffs(index));
-
-Which means that:
-
-For an input index of 0, ffs returns 0, so we set the register
-to 0x01, ok.
-
-For an input index of 1, ffs returns 1, so we set the register
-to 0x02, ok.
-
-For an input index of 2, ffs returns 2, so we set the register
-to 0x04, ok.
-
-For an input index of 3, ffs returns 1, so we set the register
-to 0x02, not good!
-
-The code should simply be:
-
- if (mux->flags & CLK_MUX_INDEX_BIT)
- index = 1 << index;
-
-Which always does the right thing, this commit fixes this.

-Krait CPUs have a handful of L2 cache controller registers that
-live behind a cp15 based indirection register. First you program
-the indirection register (l2cpselr) to point the L2 'window'
-register (l2cpdr) at what you want to read/write. Then you
-read/write the 'window' register to do what you want. The
-l2cpselr register is not banked per-cpu so we must lock around
-accesses to it to prevent other CPUs from re-pointing l2cpdr
-underneath us.

-We want to reuse the logic in clk-mux.c for other clock drivers
-that don't use readl as register accessors. Fortunately, there
-really isn't much to the mux code besides the table indirection
-and quirk flags if you assume any bit shifting and masking has
-been done already. Pull that logic out into reusable functions
-that operate on an optional table and some flags so that other
-drivers can use the same logic.

-If a clock is on and we call clk_set_rate() on it we may get into
-a situation where the clock temporarily increases in rate
-dramatically while we walk the tree and call .set_rate() ops. For
-example, consider a case where a PLL feeds into a divider.
-Initially the divider is set to divide by 1 and the PLL is
-running fairly slow (100MHz). The downstream consumer of the
-divider output can only handle rates =< 400 MHz, but the divider
-can only choose between divisors of 1 and 4.
-
- +-----+ +----------------+
- | PLL |-->| div 1 or div 4 |---> consumer device
- +-----+ +----------------+
-
-To achieve a rate of 400MHz on the output of the divider, we
-would have to set the rate of the PLL to 1.6 GHz and then divide
-it by 4. The current code would set the PLL to 1.6GHz first while
-the divider is still set to 1, thus causing the downstream
-consumer of the clock to receive a few clock cycles of 1.6GHz
-clock (far beyond it's maximum acceptable rate). We should be
-changing the divider first before increasing the PLL rate to
-avoid this problem.
-
-Therefore, set the rate of any child clocks that are increasing
-in rate from their current rate so that they can increase their
-dividers if necessary. We assume that there isn't such a thing as
-minimum rate requirements.

-Sometimes clocks can't accept their parent source turning off
-while the source is reprogrammed to a different rate. Most
-notably CPU clocks require a way to switch away from the current
-PLL they're running on, reprogram that PLL to a new rate, and
-then switch back to the PLL with the new rate once they're done.
-Add a hook that drivers can implement allowing them to return a
-'safe parent' that they can switch their parent to while the
-upstream source is reprogrammed to support this.

-This patch is good enough for Krait, but soon I'll need to
-support a "safe rate" where we ask a clock what rate it needs to be running
-at to be sure it's within voltage constraints. Right now safe parent
-handles that problem on Krait, but on other platforms it won't work.

-The Krait clocks are made up of a series of muxes and a divider
-that choose between a fixed rate clock and dedicated HFPLLs for
-each CPU. Instead of using mmio accesses to remux parents, the
-Krait implementation exposes the remux control via cp15
-registers. Support these clocks.

-The Krait CPU clocks are made up of a primary mux and secondary
-mux for each CPU and the L2, controlled via cp15 accessors. For
-Kraits within KPSSv1 each secondary mux accepts a different aux
-source, but on KPSSv2 each secondary mux accepts the same aux
-source.

-From: Stephen Boyd <sboyd@codeaurora.org>
-Date: Fri, 30 May 2014 16:36:11 -0700
-Subject: [PATCH] FROMLIST: cpufreq: Add a cpufreq-krait based on cpufreq-cpu0
-
-Krait processors have individual clocks for each CPU that can
-scale independently from one another. cpufreq-cpu0 is fairly
-close to this, but assumes that there is only one clock for all
-CPUs. Add a driver to support the Krait configuration.
-
-TODO: Merge into cpufreq-cpu0? Or make generic?
-

-
-The fact that the channel configuration is done in device_control is rather
-misleading, since it's not really advertised as such, plus, the fact that the
-framework exposes a function of its own makes it not really intuitive, while
-we're losing the type checking whenever we pass that unsigned long argument.

-Add a device_config callback to dma_device, with a fallback on the old
-behaviour for now for existing drivers to opt in.

-
-Add the DMA engine driver for the QCOM Application Data Mover (ADM) DMA
-controller found in the MSM8x60 and IPQ/APQ8064 platforms.
-
-The ADM supports both memory to memory transactions and memory
-to/from peripheral device transactions. The controller also provides flow
-control capabilities for transactions to/from peripheral devices.
-
-The initial release of this driver supports slave transfers to/from peripherals
-and also incorporates CRCI (client rate control interface) flow control.

-
-The NAND controller within EBI2 requires EBI2_CLK and
-EBI2_ALWAYS_ON_CLK clocks. Create structs for these clocks so
-that they can be used by the NAND controller driver. Add an entry
-for EBI2_AON_CLK in the gcc-ipq806x DT binding document.

-
-Some controllers can access the factory bad block marker from OOB only
-when they read it in raw mode. When ECC is enabled, these controllers
-discard reading/writing bad block markers, preventing access to them
-altogether.
-
-The bbt driver assumes MTD_OPS_PLACE_OOB when scanning for bad blocks.
-This results in the nand driver's ecc->read_oob() op to be called, which
-works with ECC enabled.
-
-Create a new BBT option flag that tells nand_bbt to force the mode to
-MTD_OPS_RAW. This would result in the correct op being called for the
-underlying nand controller driver.

-
-The Qualcomm NAND controller is found in SoCs like IPQ806x, MSM7xx,
-MDM9x15 series.
-
-It exists as a sub block inside the IPs EBI2 (External Bus Interface 2)
-and QPIC (Qualcomm Parallel Interface Controller). These IPs provide a
-broader interface for external slow peripheral devices such as LCD and
-NAND/NOR flash memory or SRAM like interfaces.
-
-We add support for the NAND controller found within EBI2. For the SoCs
-of our interest, we only use the NAND controller within EBI2. Therefore,
-it's safe for us to assume that the NAND controller is a standalone block
-within the SoC.
-
-The controller supports 512B, 2kB, 4kB and 8kB page 8-bit and 16-bit NAND
-flash devices. It contains a HW ECC block that supports BCH ECC (4, 8 and
-16 bit correction/step) and RS ECC(4 bit correction/step) that covers main
-and spare data. The controller contains an internal 512 byte page buffer
-to which we read/write via DMA. The EBI2 type NAND controller uses ADM DMA
-for register read/write and data transfers. The controller performs page
-reads and writes at a codeword/step level of 512 bytes. It can support up
-to 2 external chips of different configurations.
-
-The driver prepares register read and write configuration descriptors for
-each codeword, followed by data descriptors to read or write data from the
-controller's internal buffer. It uses a single ADM DMA channel that we get
-via dmaengine API. The controller requires 2 ADM CRCIs for command and
-data flow control. These are passed via DT.
-
-The ecc layout used by the controller is syndrome like, but we can't use
-the standard syndrome ecc ops because of several reasons. First, the amount
-of data bytes covered by ecc isn't same in each step. Second, writing to
-free oob space requires us writing to the entire step in which the oob
-lies. This forces us to create our own ecc ops.
-
-One more difference is how the controller accesses the bad block marker.
-The controller ignores reading the marker when ECC is enabled. ECC needs
-to be explicity disabled to read or write to the bad block marker. For
-this reason, we use the newly created flag NAND_BBT_ACCESS_BBM_RAW to
-read the factory provided bad block markers.
-
-v3:
-- Refactor dma functions for maximum reuse
-- Use dma_slave_confing on stack
-- optimize and clean upempty_page_fixup using memchr_inv
-- ensure portability with dma register reads using le32_* funcs
-- use NAND_USE_BOUNCE_BUFFER instead of doing it ourselves
-- fix handling of return values of dmaengine funcs
-- constify wherever possible
-- Remove dependency on ADM DMA in Kconfig
-- Misc fixes and clean ups
-
-v2:
-- Use new BBT flag that allows us to read BBM in raw mode
-- reduce memcpy-s in the driver
-- some refactor and clean ups because of above changes

-Subject: [PATCH] HACK: arch: arm: force ZRELADDR on arch-qcom
-
-ARCH_QCOM is using the ARCH_MULTIPLATFORM option, as now recommended
-on most ARM architectures. This automatically calculate ZRELADDR by
-masking PHYS_OFFSET with 0xf8000000.
-
-However, on IPQ806x, the first ~20MB of RAM is reserved for the hardware
-network accelerators, and the bootloader removes this section from the
-layout passed from the ATAGS (when used).
-
-For newer bootloader, when DT is used, this is not a problem, we just
-reserve this memory in the device tree. But if the bootloader doesn't
-have DT support, then ATAGS have to be used. In this case, the ARM
-decompressor will position the kernel in this low mem, which will not be
-in the RAM section mapped by the bootloader, which means the kernel will
-freeze in the middle of the boot process trying to map the memory.
-
-As a work around, this patch allows disabling AUTO_ZRELADDR when
-ARCH_QCOM is selected. It makes the zImage usage possible on bootloaders
-which don't support device-tree, which is the case on certain early
-IPQ806x based designs.
