Subject: [PATCH] arm64: dts: mt7622: fix BPI-R64 WPS button
|
||
|
|
|
||
|
|
The bananapi R64 (BPI-R64) experiences wrong WPS button signals.
|
||
|
|
In OpenWrt pushing the WPS button while powering on the device will set
|
||
|
|
it to recovery mode. Currently, this also happens without any user
|
||
|
|
interaction. In particular, the wrong signals appear while booting the
|
||
|
|
device or restarting it, e.g. after doing a system upgrade. If the
|
||
|
|
device is in recovery mode the user needs to manually power cycle or
|
||
|
|
restart it.
|
||
|
|
|
||
|
|
The official BPI-R64 sources set the WPS button to GPIO_ACTIVE_LOW in
|
||
|
|
the device tree. This setting seems to suppress the unwanted WPS button
|
||
|
|
press signals. So this commit changes the button from GPIO_ACTIVE_HIGH to
|
||
|
|
GPIO_ACTIVE_LOW.
|
||
|
|
|
||
|
|
