Input: stmfts - set IRQ_NOAUTOEN to the irq flag

2018-01-23T01:35:16Z

The interrupt is requested before the device is powered on and it's value in some cases cannot be reliable. It happens on some devices that an interrupt is generated as soon as requested before having the chance to disable the irq. Set the irq flag as IRQ_NOAUTOEN before requesting it. This patch mutes the error: stmfts 2-0049: failed to read events: -11 received sometimes during boot time. Signed-off-by: Andi Shyti Signed-off-by: Dmitry Torokhov

Input: stmfts - fix setting ABS_MT_POSITION_* maximum size

2017-10-19T00:54:13Z

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.

Input: stmfts - mark all PM functions as __maybe_unused

2017-06-09T16:54:56Z

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.

Input: add support for the STMicroelectronics FingerTip touchscreen

2017-06-05T22:35:34Z

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.
