The RK3308 SoC features integrated USB controllers and PHYs. The USB controller is compatible with the usual RK3066 USB controller, the phy is in general compatible with the inno-usb2 phy structure but is not quite the same as any of the phys supported yet. This patchset adds USB support for the RK3308 SoC to both the RK3308 dtsi and Rockchip inno-usb2 phy driver. I've tested this patchset on a Rock Pi S, works flawlessly with HS, FS and LS devices. This patchset depends on grf.txt to YAML conversion [1] by Johan. This is v2 of the patchset. Cheers, Tobias Changelog: v2: - switch changes over to Johan's converted yaml documentation - document "rockchip,rk3308-usb2phy-grf", "syscon", "simple-mfd" compatible - fix rockchip,rk3308-usb2phy documentation [1] https://lkml.org/lkml/2021/5/12/464 Tobias Schramm (5): dt-bindings: phy: rockchip-inno-usb2: add compatible for rk3308 USB phy phy: phy-rockchip-inno-usb2: add support for RK3308 USB phy dt-bindings: usb: dwc2: add compatible for RK3308 USB controller dt-bindings: soc: rockchip: grf: add compatible for RK3308 USB grf arm64: dts: rockchip: add USB support to RK3308 dts .../bindings/phy/phy-rockchip-inno-usb2.yaml | 1 + .../devicetree/bindings/soc/rockchip/grf.yaml | 1 + .../devicetree/bindings/usb/dwc2.yaml | 1 + arch/arm64/boot/dts/rockchip/rk3308.dtsi | 73 +++++++++++++++++++ drivers/phy/rockchip/phy-rockchip-inno-usb2.c | 44 +++++++++++ 5 files changed, 120 insertions(+) -- 2.31.1
