FWIW
trinket-sde.dtsi (downstream for this SoC):
qcom,usbplug-cc-gpio = <&tlmm 102 0>;
trinket-pinctrl.dtsi:
sde_dp_usbplug_cc_active: sde_dp_usbplug_cc_active {
mux {
pins = "gpio102";
function = "gpio"; <---
};
config {
pins = "gpio102";
bias-disable;
drive-strength = <16>;
};
};
reading the blurb in downstream's gpu/drm/msm/dp/dp_parser.c this
seems to be the select pin of a GPIO Type-C mux?
