Note that the PHY driver > currently forces the PHY to host mode always; a correction to > the PHY driver or removal of the phy values from the OHCI and EHCI > nodes are necessary to get otg mode working properly. > - Disabled SoC RTC in favor of external clock. The SoC RTC is not > set up correctly in hardware and runs fast, whereas the external RTC > keeps accurate time. This matches the BSP. > - Added labels to GPIO pins to aid in readability. > > Changes since V2: > - Add display support. > - Add USB host support. > - Removed CPU frequency and voltage parameters, as CPU regulator may > be tied into additional areas that need further testing. > - Added regulator names back, as they appear to have been accidentally > dropped in v2. > - Updated notes to denote all hardware tested and working. > > Changes since V1: > - Added additional pwm pin configs to sun8i-v3s.dtsi and removed > default config for pwm0 in lieu of defining it for each board. > - Noted in patch notes that additional hardware of UART debug port, > USB port (in gadget mode) also work, and that USB host mode does > not work. > - Identified GPIO responsible for enabling external speaker amplifier > and defined it, allowing onboard audio to work. > - Removed ac_power_supply node. > - Set regulator min and max values to the same value as defined in the > schematics. > - Removed definition for reg_ldo1. This regulator is hardware > configured so the value did not affect anything, however the driver > must be updated to support the correct value of 3.3v in this case. > - Removed usb0_id_det-gpios as I cannot confirm these are correct. > > Chris Morgan (4): > arm: dts: sun8i: V3s: Add pinctrl for pwm > ARM: dts: sun8i: v3s: add EHCI and OHCI to v3s dts > dt-bindings: arm: sunxi: add Anbernic RG-Nano > ARM: dts: sunxi: add support for Anbernic RG-Nano > > .../devicetree/bindings/arm/sunxi.yaml | 5 + > arch/arm/boot/dts/allwinner/Makefile | 1 + > .../allwinner/sun8i-v3s-anbernic-rg-nano.dts | 276 ++++++++++++++++++ > arch/arm/boot/dts/allwinner/sun8i-v3s.dtsi | 35 +++ > 4 files changed, 317 insertions(+) > create mode 100644 arch/arm/boot/dts/allwinner/sun8i-v3s-anbernic-rg-nano.dts > Applied, thanks!
