[PATCH v2 2/2] arm64: dts: rockchip: Add Bananapi R2 Pro

Frank Wunderlich
2022-01-23T13:51:34Z

From: Frank Wunderlich <frank-w@public-files.de>

This patch adds Devicetree for Bananapi R2 Pro based on RK3568.
Add uart/sd/emmc/i2c/rk809/tsadc nodes for basic function.
Gmac0 is directly connected to wan-port so usable without additional
driver.
On gmac1 there is a switch (rtl8367rb) connected which have not yet a
driver in mainline.

Patch also prepares nodes for GPIO header.

changes in v2:
- drop alias for gmac1 - currently unused due to missing switch driver
- verified / changed pinctrl of pwm/spi/uart/i2c
- add sharing information for con2 functions
- always power on vccio1 iodomain (used for rtc)
- drop V00 from model
- change leds (change names, drop label, add pinctrl, use color+function)
- add fan
