[PATCH 5.10.y-cip 02/24] arm64: dts: renesas: Add initial device tree for RZ/G2LC SMARC EVK


Biju Das
 

commit ce0c63b6a5ef86208d1008ce6c42a7a7180aaf75 upstream.

Add basic support for the RZ/G2LC SMARC EVK (based on R9A07G044C2):
- memory
- External input clock
- SCIF
- GbEthernet
- Audio Clock

It shares the same carrier board with RZ/G2L, but the pin mapping is
different. Disable the device nodes which are not tested and delete the
corresponding pinctrl definitions.
