Subject: [PATCH] [BROKEN] arm64: dts: rockchip: rk3588-rock5b: add USB-C
|
|
support
|
|
|
|
Add support for using the Radxa Rock 5 Model B USB-C port for USB in
|
|
OHCI, EHCI or XHCI mode. Displayport AltMode is not yet supported.
|
|
|
|
Note: Enabling support for the USB-C port results in a board reset
|
|
when the system is supplied with a PD capable power-supply. Until
|
|
this has been analyzed and fixed, let's disable support for the
|
|
Type-C port.
|
