Subject: 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.
|
|
|
|
Includes:
|
|
- arm64: dts: amlogic: fix interrupt storm from fusb302 on Radxa Zero
|
|
it makes load average >1. use correct pin for interrupt from fusb302.
