ARM: dts: da850-lcdk: Add NAND to DT
PATCH v2 1/1 ARM: dts: da850-lcdk: Add NAND to DT
From: Karl Beldan <[email protected]>
This adds DT support for the NAND connected to the SoC AEMIF. Passed torture hashing a 40MB file on top of UBIFS using subpages.

Applies on Sekhar's v4.9/dts branch.
Sekhar, feel free to edit the comment text for the partitions as you see fit.

Looks like you need to respin your DT series for arm-soc due to build errors. Can you add this while you're at it so we have 4-bit ECC in v4.9?
Thanks,
Kevin

The comments in the patch were fine. I applied this patch and just sent a pull request for ARM-SoC maintainers too. Hopefully its not too late for v4.9
Thanks,
