mediatek: mt7622: fix banana pi r64 wps button
Fix the wps button to prevent wrongly detected recovery procedures. In the official banana pi r64 git the wps button is set to GPIO_ACTIVE_LOW and not GPIO_ACTIVE_HIGH. Import patch to fix on boot unwanted recovery entering: Press the [f] key and hit [enter] to enter failsafe mode Press the [1], [2], [3] or [4] key and hit [enter] to select the debug level - failsafe button wps was pressed - - failsafe - Signed-off-by: Nick Hainke <vincent@systemli.org> (cherry-picked from commit 668619425526cb0d43f8536a2f6f15a6314e6553)

+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.
+
+The official BPI-R64 sources can be found on
+https://github.com/BPI-SINOVOIP/BPI-R64-openwrt
