Subject: [PATCH v2] arm64: dts: mt8183: kukui: Add Type C node
Date: Thu, 9 Dec 2021 11:51:12 -0800 [thread overview]
Message-ID: <20211209195112.366176-1-pmalani@chromium.org> (raw)
Add a node describing the USB Type C connector, in order to utilize the
Chromium OS USB Type-C driver that enumerates Type-C ports and connected
cables/peripherals and makes them visible to userspace.

Changes in v2:
- Alexandru mentioned that HW specs suggest preferred power role for
devices like kukui to be sink, so changed try-power-role to "sink".
