Subject: [PATCH 1/4] arm64: dts: rockchip: add rfkill node for M.2 Key E WiFi on rock-5b
Date: Thu, 25 Jan 2024 00:30:04 +0400 [thread overview]
Message-ID: <20240125-rk-dts-additions-v1-1-5879275db36f@gmail.com> (raw)
In-Reply-To: <20240125-rk-dts-additions-v1-0-5879275db36f@gmail.com>
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.
