Input: stmfts - acknowledge that setting brightness is a blocking call

2019-02-08T07:41:11+00:00

We need to turn regulators on and off when switching brightness, and that may block, therefore we have to set stmfts_brightness_set() as LED's brightness_set_blocking() method.

Input: stmfts, s6sy761 - update my e-mail

Because I will be leaving Samsung soon, for reachability update my reference e-mail to etezian.org. Signed-off-by: Andi Shyti Signed-off-by: Dmitry Torokhov

Input: stmfts - use async probe & suspend/resume to avoid 2s delay

2018-03-30T22:31:41+00:00

Executing stmfts_power_on() function lasts over 2 seconds, what significantly slows down the boot and resume processes if driver is compiled in. Avoid this delay by forcing this driver to be probed and suspended/resumed asynchronously. Signed-off-by: Marek Szyprowski Signed-off-by: Dmitry Torokhov

Input: stmfts - set IRQ_NOAUTOEN to the irq flag

2018-01-23T01:35:16+00:00

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,s6sy671 - add SPDX identifier

2018-01-23T00:25:48+00:00

Replace the original license statement with the SPDX identifier. Update also the copyright owner adding myself as co-owner of the copyright. Signed-off-by: Andi Shyti Signed-off-by: Dmitry Torokhov

Merge tag 'v4.14-rc6' into next

Merge with mainline to bring in the timer API changes.

Input: stmfts - fix setting ABS_MT_POSITION_* maximum size

2017-10-19T00:54:13+00:00

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 - use devm_device_add_group

Input: stmfts - mark all PM functions as __maybe_unused

2017-06-09T16:54:56+00:00

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

2017-06-05T22:35:34+00:00

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.
