> The devicetree submitted and approved for the mainline linux kernel is

> devicetrees (for the Rockchip SFC node at least) present on the PX30
> and the Odroid Go Advance. Changes include renaming the flash node,
> reordering the values in the SFC node for the rk3326-odroid-go2,
> changing the name of the cs pinctrl node to cs0, and updating the
> u-boot specific tree to utilize the new flash node value.
