[PATCH v2 2/3] arm64: dts: rockchip: add usb-id extcon on rk3588 tiger

From: Heiko Stuebner
Date: Mon Apr 22 2024 - 12:40:39 EST


From: Heiko Stuebner <heiko.stuebner@xxxxxxxxx>

The Q7 standard specifies a usb-id pin on the connector to distiuish
between host and device mode. Model this via the usb-id extcon binding.

While the pin is part of the Q7 standard, so part of the module, the
extcon stays disabled in the som dtsi and will only be enabled in a
baseboard using it.
