2019-11-11Input: mms114 - use device_get_match_dataStephan Gerhold1-2/+1
device_get_match_data is available now, so we can replace the call to of_device_get_match_data and remove the FIXME comment.

2018-02-02Input: mms114 - fix license module informationAndi Shyti1-1/+1
The driver has been released with GNU Public License v2 as stated in the header, but the module license information has been tagged as "GPL" (GNU Public License v2 or later). Fix the module license information so that it matches the one in the header as "GPL v2".

2018-01-26Input: mms114 - drop platform data and use generic APIsSimon Shields1-82/+65
The MMS114 platform data has no in-tree users, so drop it. Switch to using the standard touchscreen properties via touchscreen_parse_properties(), and move the old DT parsing code to use device_property_*() APIs. Finally, use touchscreen_report_pos to report x/y coordinates and drop the custom x/y inversion code.

2018-01-26Input: mms114 - mark as direct input deviceDmitry Torokhov1-8/+5
mms14 is a touchscreen and thus a direct input device; let's mark it as such. This also allows us to drop some initialization code as input_init_mt_slots() will do that for us. Also add error handling for input_mt_init_slots().

2015-07-30Input: touchscreen - export OF module alias informationJavier Martinez Canillas1-0/+1
The I2C core always reports the MODALIAS uevent as "i2c:<client name" regardless if the driver was matched using the I2C id_table or the of_match_table. So technically there's no need for a driver to export the OF table since currently it's not used. In fact, the I2C device ID table is mandatory for I2C drivers since a i2c_device_id is passed to the driver's probe function even if the I2C core used the OF table to match the driver. And since the I2C core uses different tables, OF-only drivers needs to have duplicated data that has to be kept in sync and also the dev node compatible manufacturer prefix is stripped when reporting the MODALIAS. To avoid the above, the I2C core behavior may be changed in the future to not require an I2C device table for OF-only drivers and report the OF module alias. So, it's better to also export the OF table to prevent breaking module autoloading if that happens.

2013-03-10Input: mms114 - Fix regulator enable and disable pathsMark Brown1-9/+25
When it uses regulators the mms114 driver checks to see if it managed to acquire regulators and ignores errors. This is not the intended usage and not great style in general. Since the driver already refuses to probe if it fails to allocate the regulators simply make the enable and disable calls unconditional and add appropriate error handling, including adding cleanup of the regulators if setup_reg() fails.
