This patchset adds device tree support to the MXS NAND driver. This also allows to use fixed ECC strenght usingt he device tree properties nand-ecc-strength/nand-ecc-step-size and aligns behavior with the Linux GPMI NAND driver.
This is based on the "mtd: nand: mxs_nand: improve ECC support" patchset: https://patchwork.ozlabs.org/cover/897263/
Support for nand-ecc-strength/nand-ecc-step-size has recently been added in Linux, see: https://patchwork.kernel.org/patch/10257829/
This patchset has been tested with various ECC configurations on a Colibri iMX7.
