[draft2 PATCH] ARM: dts: sun8i: r40: add devicetree for FETA40i-C/OKA40i-C

Ivan Uvarov i.uvarov at cognitivepilot.com
Tue Mar 2 10:54:15 GMT 2021 

From: Ivan Uvarov <i.uvarov at cognitivepilot.com>

This patch adds support for the Forlinx FETA40i-C SoM and OKA40i-C
devboard[1] that is based on it. The devicetree is split into a .dtsi 
which (hopefully) corresponds to the functions of the SoM itself and 
a .dts for the devboard.
