Subject: [PATCH] lantiq: backport kernel patch to pass of node to nand_dt_init
Backport upstream commit a61ae81a1907af1987ad4c77300508327bc48b23.
The actually purpose of the patch was to do some cleanup. As a side
effect of this cleanup, the device node is now passed to nand_dt_init.
This allows to use the common nand device tree properties
- nand-bus-width
- nand-on-flash-bbt
- nand-ecc-mode
- nand-ecc-step-size
- nand-ecc-strength
for the plat_nand driver.
