There was a mistake in my devicetree. The HSIC ports are working when I set the
dts entries like this:
&usbh2 {
pinctrl-names = "idle", "active";
pinctrl-0 = <&pinctrl_usbh2_1>;
pinctrl-1 = <&pinctrl_usbh2_2>;
osc-clkgate-delay = <0x3>;
status = "okay";
};
&usbh3 {
pinctrl-names = "idle", "active";
pinctrl-0 = <&pinctrl_usbh3_1>;
pinctrl-1 = <&pinctrl_usbh3_2>;
osc-clkgate-delay = <0x3>;
status = "okay";
};
&fec {
#address-cells = <1>;
#size-cells = <0>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_enet_poc20>;
phy-mode = "mii";
status = "okay";
phy = <&phy3>;
phy3: ethernet-phy@3 {
reg = <3>;
device_type = "ethernet-phy";
};
};
Best regards,
Rolf
