From 4ce03bb80faed41e04b7d6f089275d262f4cfc79 Mon Sep 17 00:00:00 2001 From: Marijn Suijten Date: Tue, 10 Jan 2023 00:41:32 +0100 Subject: [PATCH] arm64: dts: qcom: sdm845-tama: Add volume up and camera GPIO keys Tama has four GPIO-wired keys: two for camera focus and shutter / snapshot, and two more for volume up and down. As per the comment these used to not work because the necessary pin bias was missing, which is now set via pinctrl on pm8998_gpios. The missing bias has also been added to the existing volume down button, which receives a node name and label cleanup at the same time to be more consistent with other DTS and the newly added buttons. Its deprecated gpio-key,wakeup property has also been replaced with wakeup-source. Note that volume up is also available through the usual PON RESIN node, but unlike other platforms only triggers when the power button is held down at the same time making it unsuitable to serve as KEY_VOLUMEUP.
