Subject: [PATCH v8 19/52] Input: atmel_mxt_ts - allow input name to be specified in platform data
Date: Thu, 19 Mar 2020 07:59:43 -0700
Message-ID: <20200319150016.61398-20-jiada_wang@mentor.com> (raw)
In-Reply-To: <20200319150016.61398-1-jiada_wang@mentor.com>

From: Nick Dyer <nick.dyer@itdev.co.uk>

Android systems identify the input device and map to IDC file by using the
input device name. To avoid unnecessary deltas to the driver file, allow
this to be set from the platform data.
