[PATCH v2] arm64: dts: qcom: sm8350-sagami: Rectify GPIO keys

From: Konrad Dybcio
Date: Tue Dec 13 2022 - 07:10:06 EST


With enough pins set properly, the hardware buttons now also work
like a charm.

Fixes: c2721b0c23d9 ("arm64: dts: qcom: Add support for Xperia 1 III / 5 III")
Tested-by: Marijn Suijten <marijn.suijten@xxxxxxxxxxxxxx> # On Xperia 5 III
Signed-off-by: Konrad Dybcio <konrad.dybcio@xxxxxxxxxx>
---
Changes in v2:
- Look at the 1 III again, realize there's a recessed button, add it
to the common DT to make it work on both devices.. (Marijn)
