As per the comment these used to not work because the necessary pin bias was missing, which is now set via pinctrl on pm8998_gpio(s). 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.
