[PATCH v3 09/10] ARM: dts: suniv: Add device tree files and bindings for F1C100s

Jesse Taube
2022-01-29T15:24:52Z

Add device tree files for suniv and
Lichee Pi Nano it is a board based on F1C100s.
dt-bindings/dts are synced with 5.16.0

V1->V2:
* Sync with Linux
* Re-add MMC node
V2->V3:
* Add ifndef for mmc in sunxi-u-boot.dtsi
* Direct copy of all files from linux
* Squash dt-bindings here
