Subject: [PATCH v5] arm64: dts: qcom: qcm6490-idp: enable PMIC Volume and
Power buttons
From: Hui Liu <quic_huliu@...cinc.com>
The Volume Down & Power buttons are controlled by the PMIC via
the PON hardware, and the Volume Up is connected to a PMIC gpio.
Enable the necessary hardware and setup the GPIO state for the
Volume Up gpio key.

Changes in v5:
- Removed the status setting for pmk8350_pon, because the default
status is "okay".
- Link to v4: https://lore.kernel.org/r/20240304-gpio-keys-v4-1-03604d778c86@quicinc.com
Changes in v4:
- Switch the order of "pinctrl-0" and "pinctrl-names".
- Update "volume_up" to "Volume_up".
- Remove "linux,input-type", because the default value is 1(EV_KEY).
- Link to v3: https://lore.kernel.org/r/20240301-gpio-keys-v3-1-ca664de8775c@quicinc.com
Changes in v3:
- Update the commit more concise and explicit.
- remove "power-source" property and update the numeric value to defined
name for "qcom,drive-strength".
- Link to v2: https://lore.kernel.org/r/20240223-gpio-keys-v2-1-19f48b3d8762@quicinc.com
Changes in v2:
- Update the commit description.
- Link to v1: https://lore.kernel.org/r/20240206-gpio-keys-v1-1-7683799daf8d@quicinc.com
