From 82d40b141a4c7ab6608a84a5ce0c58b747cb7163 Mon Sep 17 00:00:00 2001 From: Alexey Charkov Date: Sun, 7 Jan 2024 00:26:45 +0400 Subject: [PATCH] arm64: dts: rockchip: add rfkill node for M.2 Key E WiFi on rock-5b 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.
