linux.git/drivers/input/touchscreen, branch v4.13

Merge branch 'next' into for-linus

2017-07-06T20:51:43+00:00

Prepare input updates for 4.13 merge window.

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.

Input: s3c2410_ts - handle return value of clk_prepare_enable

2017-06-03T00:57:26+00:00

clk_prepare_enable() can fail here and we must check its return value.

Merge tag 'v4.12-rc3' into for-linus

2017-06-03T00:49:10+00:00

Merge with mainline to get acpi_dev_present() needed by patches to
axp20x-pek driver.

Input: silead - disable interrupt during suspend

2017-05-30T02:58:25+00:00

When we put the touchscreen controller in low-power mode the irq
pin may trigger (float) and if we then try to read a data packet we
get the following error in dmesg:

[  478.801017] silead_ts i2c-MSSL1680:00: Data read error -121

This commit disables the irq during suspend/resume fixing this error.

Merge tag 'v4.12-rc3' into next

2017-05-30T02:54:21+00:00

Sync with mainline to bring in changes in platform drovers dropping
calls to sparse_keymap_free() so that we can remove it for good.
