Subject: [PATCH] arm64: dts: rockchip: add rfkill node for M.2 Key E WiFi on rock-5b
Date: Sun,  7 Jan 2024 00:26:45 +0400	[thread overview]
Message-ID: <20240106202650.22310-1-alchark@gmail.com> (raw)

By default the GPIO pin that connects to the WiFi enable signal
inside the M.2 Key E slot is driven low, resulting in impossibility
to connect to any network. Add a DT node to expose it as an RFKILL
device, which lets the WiFi driver or userspace toggle it as
required.
