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.

Could you elaborate a bit the point of splitting imx6ull-seeed-npi.dtsi
and imx6ull-seeed-npi-dev-board.dtsi? Why cannot they be a single file?

imx6ull-seeed-npi.dtsi is for the npi SoM and -dev-board is for the board which uses the SoM.
