See the patch [1] by Sebastian for EVB1 [1] https://lore.kernel.org/linux-rockchip/20250910-rk3576-evb-network-v1-1-68ed4df272a2@collabora.com/ > + }; > +}; > + > +&mdio1 { > + rgmii_phy1: ethernet-phy@1 { > + compatible = "ethernet-phy-id4f51.e91b"; > + reg = <0x1>; > + pinctrl-names = "default"; > + pinctrl-0 = <&rgmii_phy1_rst>; > + reset-assert-us = <20000>; > + reset-deassert-us = <100000>; > + reset-gpios = <&gpio3 RK_PD6 GPIO_ACTIVE_LOW>; Ditto > + }; > +}; > + > +&pinctrl { > + bluetooth { > + bt_reg_on: bt-reg-on { > + rockchip,pins = <1 RK_PC7 RK_FUNC_GPIO &pcfg_pull_up>; > + }; > + > + bt_wake_host: bt-wake-host { > + rockchip,pins = <0 RK_PB1 RK_FUNC_GPIO &pcfg_pull_down>; > + }; > + > + host_wake_bt: host-wake-bt { > + rockchip,pins = <1 RK_PD4 RK_FUNC_GPIO &pcfg_pull_up>; > + }; > + }; > + > + hym8563 { > + rtc_int: rtc-int { > + rockchip,pins = <0 RK_PA5 RK_FUNC_GPIO &pcfg_pull_up>; > + }; > + }; > + > + network { > + rgmii_phy0_rst: rgmii-phy0-rst { > + rockchip,pins = <3 RK_PD3 RK_FUNC_GPIO &pcfg_pull_none>; > + }; > + > + rgmii_phy1_rst: rgmii-phy1-rst { > + rockchip,pins = <3 RK_PD6 RK_FUNC_GPIO &pcfg_pull_none>; > + }; > + }; > + > + pcie1 { > + pcie1_rst: pcie1-rst { > + rockchip,pins = <4 RK_PA0 RK_FUNC_GPIO &pcfg_pull_none>; > + }; > + }; > + > + sata { > + satapm_pwren: satapm-pwren { > + rockchip,pins = <4 RK_PC7 RK_FUNC_GPIO &pcfg_output_high>; Should this one become a regulator, instead of just statically configuring it for high output? This looks fragile: I can imagine a user toggling GPIOs at random in search for some pin they need, and suddenly powering down their SATA port, potentially with data loss. With a pin configured as a fixed voltage regulator the kernel would say that it's in use in such a scenario. > + }; > + }; > + > + usb { > + usb_host_pwren: usb-host-pwren { > + rockchip,pins = <0 RK_PC3 RK_FUNC_GPIO &pcfg_pull_none>; > + }; > + > + usb_otg0_pwren: usb-otg0-pwren { > + rockchip,pins = <0 RK_PD1 RK_FUNC_GPIO &pcfg_pull_none>; > + }; > + > + usbc0_int: usbc0-int { > + rockchip,pins = <0 RK_PC5 RK_FUNC_GPIO &pcfg_pull_up>; You don't seem to be requesting this pin config from anywhere, do you?

Conversely, the Type-C DP does not require these descriptions. Sorry for the confusion, but there is indeed no Type-C interface on the EVB2. And yes, I believe this is a beginning for us to upstream the RK3576 DP in mainline :) >> + status = "okay"; >> +}; >> + >> +&usb_drd0_dwc3 { >> + dr_mode = "host"; > > No OTG capability here?
