Subject: [PATCH] arm64: dts: qcom: sm8250-samsung-common: correct reserved pins
Date: Sun, 21 Sep 2025 13:56:23 +0000 [thread overview]
Message-ID: <20250921135623.273662-1-ghatto404@gmail.com> (raw)
The S20 series has additional reserved pins for the fingerprint sensor,
GPIO 20-23. Correct it by adding them into gpio-reserved-ranges.
