The VBUS control (PWREN) and over-current pins of USB 3.0 DWC3 controllers are on Exynos5410 regular GPIOs. This is different than for example on Exynos5422 where these are special ETC pins with proper reset values (pulls, functions). Therefore these pins should be configured to enable proper USB 3.0 peripheral and host modes. This also fixes over-current warning: [ 6.024658] usb usb4-port1: over-current condition [ 6.028271] usb usb3-port1: over-current condition Fixes: cb0896562228 ("ARM: dts: exynos: Add USB to Exynos5410") Signed-off-by: Krzysztof Kozlowski Cc: Link: https://lore.kernel.org/r/20201015182044.480562-2-krzk@kernel.org Tested-by: Gabriel Ribba Esteva Signed-off-by: Greg Kroah-Hartman --- arch/arm/boot/dts/exynos5410-pinctrl.dtsi | 28 ++++++++++++++++++++++++++++ arch/arm/boot/dts/exynos5410.dtsi | 4 ++++ 2 files changed, 32 insertions(+) --- a/arch/arm/boot/dts/exynos5410-pinctrl.dtsi +++ b/arch/arm/boot/dts/exynos5410-pinctrl.dtsi @@ -560,6 +560,34 @@ interrupt-controller; #interrupt-cells = <2>; }; + + usb3_1_oc: usb3-1-oc { + samsung,pins = "gpk2-4", "gpk2-5"; + samsung,pin-function = ; + samsung,pin-pud = ; + samsung,pin-drv = ; + }; + + usb3_1_vbusctrl: usb3-1-vbusctrl { + samsung,pins = "gpk2-6", "gpk2-7"; + samsung,pin-function = ; + samsung,pin-pud = ; + samsung,pin-drv = ; + }; + + usb3_0_oc: usb3-0-oc { + samsung,pins = "gpk3-0", "gpk3-1"; + samsung,pin-function = ; + samsung,pin-pud = ; + samsung,pin-drv = ; + }; + + usb3_0_vbusctrl: usb3-0-vbusctrl { + samsung,pins = "gpk3-2", "gpk3-3"; + samsung,pin-function = ; + samsung,pin-pud = ; + samsung,pin-drv = ; + }; }; &pinctrl_2 { --- a/arch/arm/boot/dts/exynos5410.dtsi +++ b/arch/arm/boot/dts/exynos5410.dtsi @@ -392,6 +392,8 @@ &usbdrd3_0 { clocks = <&clock CLK_USBD300>; clock-names = "usbdrd30"; + pinctrl-names = "default"; + pinctrl-0 = <&usb3_0_oc>, <&usb3_0_vbusctrl>; }; &usbdrd_phy0 { @@ -403,6 +405,8 @@ &usbdrd3_1 { clocks = <&clock CLK_USBD301>; clock-names = "usbdrd30"; + pinctrl-names = "default"; + pinctrl-0 = <&usb3_1_oc>, <&usb3_1_vbusctrl>; }; &usbdrd_dwc3_1 {
