The default configuration on this board, on Type-C connector, is: - Dual Power Role (DRP), so set power-role to "dual"; - Vbus limited to 500mA, so set power-opmode to "default" (it means 500mA in USB 2.0). power-opmode is used to reconfigure the STUSB1600 advertising of current capability when its NVM is not in line with the board layout. On stm32mp15xx-dkx, Vbus power source of STUSB1600 is 5V_VIN (so add the vin fixed 5V regulator too). So power operation mode depends on the power supply used. To avoid any power issues, it is better to limit Vbus to 500mA on this board. ALERT# is the interrupt pin of STUSB1600. It needs an external pull-up, and signal is active low. USB OTG controller ID and Vbus signals are not connected on stm32mp15xx-dkx boards, so disconnection are not detected. If you unplug the USB cable from the Type-C port, you have to manually disconnect the USB gadget: echo disconnect > /sys/devices/platform/soc/49000000.usb-otg/udc/49000000.usb-otg/soft_connect Then you can plug the USB cable again in the Type-C port, and manually reconnect the USB gadget: echo connect > /sys/devices/platform/soc/49000000.usb-otg/udc/49000000.usb-otg/soft_connect Signed-off-by: Amelie Delaunay --- arch/arm/boot/dts/stm32mp15-pinctrl.dtsi | 7 +++++ arch/arm/boot/dts/stm32mp15xx-dkx.dtsi | 38 ++++++++++++++++++++++++ 2 files changed, 45 insertions(+) diff --git a/arch/arm/boot/dts/stm32mp15-pinctrl.dtsi b/arch/arm/boot/dts/stm32mp15-pinctrl.dtsi index 7eb858732d6d..55deaa52c3ee 100644 --- a/arch/arm/boot/dts/stm32mp15-pinctrl.dtsi +++ b/arch/arm/boot/dts/stm32mp15-pinctrl.dtsi @@ -1574,6 +1574,13 @@ }; }; + stusb1600_pins_a: stusb1600-0 { + pins { + pinmux = ; + bias-pull-up; + }; + }; + usart2_pins_a: usart2-0 { pins1 { pinmux = , /* USART2_TX */ diff --git a/arch/arm/boot/dts/stm32mp15xx-dkx.dtsi b/arch/arm/boot/dts/stm32mp15xx-dkx.dtsi index 70db923a45f7..8d55f3fd06b3 100644 --- a/arch/arm/boot/dts/stm32mp15xx-dkx.dtsi +++ b/arch/arm/boot/dts/stm32mp15xx-dkx.dtsi @@ -80,6 +80,14 @@ dais = <&sai2a_port &sai2b_port &i2s2_port>; status = "okay"; }; + + vin: vin { + compatible = "regulator-fixed"; + regulator-name = "vin"; + regulator-min-microvolt = <5000000>; + regulator-max-microvolt = <5000000>; + regulator-always-on; + }; }; &adc { @@ -230,6 +238,30 @@ /delete-property/dmas; /delete-property/dma-names; + stusb1600@28 { + compatible = "st,stusb1600"; + reg = <0x28>; + interrupts = <11 IRQ_TYPE_EDGE_FALLING>; + interrupt-parent = <&gpioi>; + pinctrl-names = "default"; + pinctrl-0 = <&stusb1600_pins_a>; + status = "okay"; + vdd-supply = <&vin>; + + connector { + compatible = "usb-c-connector"; + label = "USB-C"; + power-role = "dual"; + power-opmode = "default"; + + port { + con_usbotg_hs_ep: endpoint { + remote-endpoint = <&usbotg_hs_ep>; + }; + }; + }; + }; + pmic: stpmic@33 { compatible = "st,stpmic1"; reg = <0x33>; @@ -599,6 +631,12 @@ phys = <&usbphyc_port1 0>; phy-names = "usb2-phy"; status = "okay"; + + port { + usbotg_hs_ep: endpoint { + remote-endpoint = <&con_usbotg_hs_ep>; + }; + }; }; &usbphyc {
