Subject: [PATCH v2] input: touchscreen: ar1021_i2c: highlight support for AR1020
Date: Fri, 14 Apr 2017 08:02:56 +0200 [thread overview]
Message-ID: <1492149776-14696-1-git-send-email-martin.kepplinger@ginzinger.com> (raw)
In-Reply-To: <20170413203532.thktt4yhqsg34cvc@rob-hp-laptop>
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.
