[PATCH v2] input: touchscreen: ar1021_i2c: highlight support for AR1020

Show all headers | View raw

ar1021_i2c simply also supports the ar1020 device I'm using. This is
tested. They also share the same datasheet:

   http://ww1.microchip.com/downloads/en/DeviceDoc/40001393C.pdf

So let users see that they have a compatible in front of them by adding
AR1020 to the driver's description.
