Subject: [PATCH 15/18] arm64: dts: rk3399-pinephone-pro: Full support for
Type-C port
Connect various devices to a extcon bridge. Fix some incorrectly
specified regulators. With this patch, this is now supported:
- PD charger / current limiting
- Alt-DisplayPort mode
- OTG - host/peripheral USB
- B1.2 detection
