2017-10-19Input: stmfts - fix setting ABS_MT_POSITION_* maximum sizeChanwoo Choi1-4/+2
The commit 78bcac7b2ae1e ("Input: add support for the STMicroelectronics FingerTip touchscreen) used the 'touchscreen_parse_properties()' helper function in order to get the value of common properties. But, commit 78bcac7b2ae1e didn't set the capability of ABS_MT_POSITION_* before calling touchscreen_parse_properties(). In result, the max_x and max_y of 'struct touchscreen_properties' were not set.

2017-06-09Input: stmfts - mark all PM functions as __maybe_unusedArnd Bergmann1-2/+2
We get a harmless warning when CONFIG_RUNTIME_PM is disabled: drivers/input/touchscreen/stmfts.c:760:12: error: 'stmfts_runtime_resume' defined but not used [-Werror=unused-function] static int stmfts_runtime_resume(struct device *dev) drivers/input/touchscreen/stmfts.c:748:12: error: 'stmfts_runtime_suspend' defined but not used [-Werror=unused-function] static int stmfts_runtime_suspend(struct device *dev) The regular PM functions are already marked as __maybe_unused, so let's do the same for the runtime-PM as well.

2017-06-06Input: add support for the STMicroelectronics FingerTip touchscreenAndi Shyti1-0/+822
The stmfts (ST-Microelectronics FingerTip S) touchscreen device is a capacitive multi-touch controller mainly for mobile use. It's connected through i2c bus at the address 0x49 and it interfaces with userspace through input event interface. At the current state it provides a touchscreen multitouch functionality up to 10 fingers. Each finger is enumerated with a distinctive id (from 0 to 9). If enabled the device can support single "touch" hovering, by providing three coordinates, x, y and distance. It is possible to select the touchkey functionality which provides a basic two keys interface for "home" and "back" menu, typical in mobile phones.
