In the past Rockchip dwc3 usb nodes were manually checked. With the conversion of snps,dwc3.yaml as common document we now can convert rockchip,dwc3.txt to yaml as well. Remove node wrapper. Added properties for rk3399 are: power-domains resets reset-names Signed-off-by: Johan Jonker <jbx6244@gmail.com> --- Changed V3: remove aclk_usb3_rksoc_axi_perf remove aclk_usb3 Changed V2: remove node wrapper --- .../devicetree/bindings/usb/rockchip,dwc3.txt | 56 ------------- .../devicetree/bindings/usb/rockchip,dwc3.yaml | 95 ++++++++++++++++++++++ 2 files changed, 95 insertions(+), 56 deletions(-) delete mode 100644 Documentation/devicetree/bindings/usb/rockchip,dwc3.txt create mode 100644 Documentation/devicetree/bindings/usb/rockchip,dwc3.yaml
