Peripheral USB-C

SBC ORCA

In SBC Orca two USB-C ports were mounted, that is:

• USB-C 1
• USB-C 2

USB-C 1

The USB-C 1 port is used to power-supply the board and for the transfer of data by Downstream-Facing Port (DFP) mode. The connector that is inserted in this port works in both side.

In U-Boot you can use this port only to power-supply the board and not for data transfer. In Linux you can use this port for data transfer.

For more information, refer to the example in USB1 OTG.

USB-C 2

The USB-C 2 port is used for data transfer. The connector that is inserted in this port works in both side.

In U-Boot you can use this port to transmit data with an external device, Downstream-Facing Port (DFP) mode, and to use the UUU functionality of NXP. In Linux you can use the Dual-Role Data mode (DRD).

For more information, refer to the example in USB2 OTG.

Device tree configuration in ORCA SOM

From imx8mp-mito8mplus-cb1001.dts:

&iomuxc {
	pinctrl_ptn5150: ptn5150grp {
		fsl,pins = <
			MX8MP_IOMUXC_GPIO1_IO00__GPIO1_IO00	0x156
			MX8MP_IOMUXC_GPIO1_IO14__GPIO1_IO14 0x16
		>;
	};
...
...
	extcon_usbotg2: typec@3d {
		compatible = "nxp,ptn5150";
		reg = <0x3d>;
		int-gpios = <&gpio1 00 GPIO_ACTIVE_LOW>;
		vbus-gpio = <&gpio1 14 GPIO_ACTIVE_HIGH>;
		pinctrl-names = "default";
		pinctrl-0 = <&pinctrl_ptn5150>;
		status = "okay";
	};
