Goodix touchscreen controller supports the ability to update its settings
at runtime. Currently, the driver supports this by loading a firmware
and reconfiguring the panel. However, this may lead to a large quantity
of firmwares being created and managed. This is a hassle since likely a
preexisting firmware or even the default configuration is good enough and
only a couple of changes need to be made.
This patchset adds the capability to dynamically alter the firmware
utilizing several new DT properties.
These new properties will allow a user to specify the touchscreen
resolution and also allow x and y coordinates to be interchanged. All of
this configuration changes are done dynamically by the driver and can work
using the default touchscreen controller configuration or even on top of
a firmware that was loaded.
