Yes, the usb2phy is always available as an extcon unless you make a device that doesn't have usb2 capability. In that case you'd have to override the device anyways. If we want to turn on default role otg here, we'd need this defined here as well or things break. > > Best regards, > Michael > > > + maximum-speed = "high-speed"; > > +}; > > diff --git a/arch/arm64/boot/dts/rockchip/rk3568.dtsi b/arch/arm64/boot/dts/rockchip/rk3568.dtsi > > index 5b0f528d6818..8ba9334f9753 100644 > > --- a/arch/arm64/boot/dts/rockchip/rk3568.dtsi > > +++ b/arch/arm64/boot/dts/rockchip/rk3568.dtsi > > @@ -99,6 +99,10 @@ opp-1992000000 { > > }; > > }; > > > > +&pipegrf { > > + compatible = "rockchip,rk3568-pipe-grf", "syscon"; > > +}; > > + > > &power { > > power-domain@RK3568_PD_PIPE { > > reg = <RK3568_PD_PIPE>; > > @@ -114,3 +118,8 @@ power-domain@RK3568_PD_PIPE { > > #power-domain-cells = <0>; > > }; > > }; > > + > > +&usb_host0_xhci { > > + phys = <&usb2phy0_otg>, <&combphy0 PHY_TYPE_USB3>; > > + phy-names = "usb2-phy", "usb3-phy"; > > +}; > > diff --git a/arch/arm64/boot/dts/rockchip/rk356x.dtsi b/arch/arm64/boot/dts/rockchip/rk356x.dtsi > > index 7cdef800cb3c..072bb9080cd6 100644 > > --- a/arch/arm64/boot/dts/rockchip/rk356x.dtsi > > +++ b/arch/arm64/boot/dts/rockchip/rk356x.dtsi > > @@ -230,6 +230,40 @@ scmi_shmem: sram@0 { > > }; > > }; > > > > + usb_host0_xhci: usb@fcc00000 { > > + compatible = "snps,dwc3"; > > + reg = <0x0 0xfcc00000 0x0 0x400000>; > > + interrupts = <GIC_SPI 169 IRQ_TYPE_LEVEL_HIGH>; > > + clocks = <&cru CLK_USB3OTG0_REF>, <&cru CLK_USB3OTG0_SUSPEND>, > > + <&cru ACLK_USB3OTG0>; > > + clock-names = "ref_clk", "suspend_clk", > > + "bus_clk"; > > + dr_mode = "host"; > > + phy_type = "utmi_wide"; > > + power-domains = <&power RK3568_PD_PIPE>; > > + resets = <&cru SRST_USB3OTG0>; > > + snps,dis_u2_susphy_quirk; > > + status = "disabled"; > > + }; > > + > > + usb_host1_xhci: usb@fd000000 { > > + compatible = "snps,dwc3"; > > + reg = <0x0 0xfd000000 0x0 0x400000>; > > + interrupts = <GIC_SPI 170 IRQ_TYPE_LEVEL_HIGH>; > > + clocks = <&cru CLK_USB3OTG1_REF>, <&cru CLK_USB3OTG1_SUSPEND>, > > + <&cru ACLK_USB3OTG1>; > > + clock-names = "ref_clk", "suspend_clk", > > + "bus_clk"; > > + dr_mode = "host"; > > + phys = <&usb2phy0_host>, <&combphy1 PHY_TYPE_USB3>; > > + phy-names = "usb2-phy", "usb3-phy"; > > + phy_type = "utmi_wide"; > > + power-domains = <&power RK3568_PD_PIPE>; > > + resets = <&cru SRST_USB3OTG1>; > > + snps,dis_u2_susphy_quirk; > > + status = "disabled"; > > + }; > > + > > gic: interrupt-controller@fd400000 { > > compatible = "arm,gic-v3"; > > reg = <0x0 0xfd400000 0 0x10000>, /* GICD */ > > @@ -297,7 +331,6 @@ pmu_io_domains: io-domains { > > }; > > > > pipegrf: syscon@fdc50000 { > > - compatible = "rockchip,rk3568-pipe-grf", "syscon"; > > reg = <0x0 0xfdc50000 0x0 0x1000>; > > }; > >
