[PATCH 2/2] ARM: dts: imx6ull: add seeed studio NPi dev board

[Parthiban Nallathambi]

Add support for Seed Stuidos NPi i.MX6ULL SoM equipped with
512MB RAM and 8GB eMMC or 512MB NAND flash. Development
board comes with either eMMC or NAND based SoM with peripheral
interfaces like 2 x ethernet, 2 x USB, LCD, CSI and more.

This is an automated instruction, just in case, because many review tags

not feel offended by me posting it here - no bad intentions intended).
If you do not know the process, here is a short explanation:

Please add Acked-by/Reviewed-by/Tested-by tags when posting new
versions, under or above your Signed-off-by tag. Tag is "received", when
provided in a message replied to you on the mailing list. Tools like b4
can help here. However, there's no need to repost patches *only* to add
the tags. The upstream maintainer will do that for tags received on the

My bot found new DT warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade

Yes I noticed the same in my end. AFAIK these warnings are from existing dtsi. Quick check different dtb resulted the same,
