Both T100 and T9 handle range and orientation in a similar fashion. Reduce duplication between the two implementations. Signed-off-by: Nick Dyer <nick.dyer@itdev.co.uk> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
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.

Apparently people are installing generic Linux distributions not only on Pixels but also on other Chromebooks. Unfortunately on all of them Atmel parts assigned names ATML0000 and ATML0001, and do not carry any other configuration data. So let's create generic instance of platform data that should cover most of them (we assume that they will not be using T100 objects, since with those Google mapped BTN_LEFT onto a different GPIO, so slightly different keymap would be needed, but I think we used parts with T100 on ARM devices where we thankfully have DTS and can describe the devices better).

We use sscanf to parse the configuration file, so it's necessary to zero terminate the configuration otherwise a truncated file can cause the parser to run off into uninitialised memory. Signed-off-by: Nick Dyer <nick.dyer@itdev.co.uk>
