   4 Subject: [PATCH] arm64: dts: rockchip: add rfkill node for M.2 Key E WiFi on rock-5b
   5
   6 By default the GPIO pin that connects to the WiFi enable signal
   7 inside the M.2 Key E slot is driven low, resulting in impossibility
   8 to connect to any network. Add a DT node to expose it as an RFKILL
   9 device, which lets the WiFi driver or userspace toggle it as
  10 required.
