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

Do we know why we are not reporting modalias as "of:..." so that
autoloading using the of table works properly?

It sounds like the of matching and modalias is quite a mess at the
moment.

I already explained the issues with OF modalias and why I believe
$SUBJECT is the least bad solution for now until the I2C subsystem
is changed to properly report OF modalias.

Please let me know if you are considering applying this or if
module autoloading will be broken for this driver in the meantime.
 

Thanks.
