    Subject[PATCH v11 23/56] Input: atmel_mxt_ts - allow input name to be specified in platform data
    Date
    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.
