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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
