   4 Subject: [PATCH] arm64: dts: mt7622: fix BPI-R64 WPS button
   5
   6 The bananapi R64 (BPI-R64) experiences wrong WPS button signals.
   7 In OpenWrt pushing the WPS button while powering on the device will set
   8 it to recovery mode. Currently, this also happens without any user
   9 interaction. In particular, the wrong signals appear while booting the
  10 device or restarting it, e.g. after doing a system upgrade. If the
  11 device is in recovery mode the user needs to manually power cycle or
  12 restart it.
  13
  14 The official BPI-R64 sources set the WPS button to GPIO_ACTIVE_LOW in
  15 the device tree. This setting seems to suppress the unwanted WPS button
  16 press signals. So this commit changes the button from GPIO_ACTIVE_HIGH to
  17 GPIO_ACTIVE_LOW.
