Subject: [PATCH 49/92] WIP: arm64: dts: meson: radxa-zero: add support for the
|
|
usb type-c controller
|
|
|
|
Radxa Zero uses an FUSB302 type-c controller, so lets enable it.
|
|
|
|
NB: Polarity swapping via GPIO is not implemented in the current driver
|
|
(see drivers/usb/typec/tcpm/fusb302.c) so it is not possible to handle
|
|
GPIOAO_6 for USB3 polarity control.
|
