    Input: atmel_mxt_ts - add maxtouch to I2C table for module autoload · b7d21058
    Javier Martinez Canillas authored
    The Atmel maxtouch DT binding documents that the compatible string for
    the device is "atmel,maxtouch" and the I2C core always reports a module
    alias of the form i2c:alias where alias is the compatible string model:
    
    $ grep MODALIAS /sys/devices/platform/12e00000.i2c/i2c-8/8-004b/uevent
    MODALIAS=i2c:maxtouch
    
    But there isn't maxtouch entry in the I2C device ID table so when the
    i2c:maxtouch MODALIAS uevent is reported, kmod is not able to match the
    alias with a module to load:
    
    $ modinfo atmel_mxt_ts | grep alias
    alias:          of:N*T*Catmel,maxtouch
    alias:          i2c:mXT224
    alias:          i2c:atmel_mxt_tp
    alias:          i2c:atmel_mxt_ts
    alias:          i2c:qt602240_ts
    
    So add the maxtouch entry to the I2C device ID table to allow the module
    to be autoloaded when the device is registered via OF.
