Subject: [PATCH v2] arm64: dts: qcom: sm6125-seine: Clean up gpio-keys (volume down)

- Remove autorepeat (leave key repetition to userspace);
- Remove unneeded status = "okay" (this is the default);
- Remove unneeded linux,input-type <EV_KEY> (this is the default for
  gpio-keys);
- Allow the interrupt line for this button to be disabled;
- Use a full, descriptive node name;
- Set proper bias on the GPIO via pinctrl;
- Sort properties;
- Replace deprecated gpio-key,wakeup property with wakeup-source.

Fixes: 82e1783890b7 ("arm64: dts: qcom: sm6125: Add support for Sony Xperia 10II")
Signed-off-by: Marijn Suijten <marijn.suijten@...ainline.org>
---

Changes since v1:

- Flatten gpio-keys pinctrl state into controlling just the volume-down
  pin;
- Replace deprecated gpio-key,wakeup property with wakeup-source.

v1: https://lore.kernel.org/linux-arm-msm/20221217100455.52593-1-marijn.suijten@somainline.org/
