Subject: [PATCH V2] arm64: dts: qcom: arduino-imola: fix faulty spidev node
Date: Thu, 12 Feb 2026 16:23:29 +0100 [thread overview]
Message-ID: <20260212152329.134065-1-r.mereu.kernel@arduino.cc> (raw)
From: Riccardo Mereu <r.mereu@arduino.cc>
CS pin added on pinctrl0 property is causing spidev to return -ENODEV
since that GPIO is already part of spi5 pinmuxing.
Fixes: 3f745bc0f11f ("arm64: dts: qcom: qrb2210: add dts for Arduino unoq")
