2016-10-03Input: elantech - force needed quirks on Fujitsu H760Matti Kurkela1-0/+14
Just like Fujitsu CELSIUS H730, the H760 also has an Elantech touchpad with the same quirks. Without this patch, the touchpad is useless out-of-the-box as the mouse pointer won't move. This patch makes the driver aware of both the crc_enabled=1 requirement and the middle button, making the touchpad fully functional out-of-the-box.

2016-10-03Input: elan_i2c - fix return tests of i2c_smbus_read_block_data()Benjamin Tissoires1-8/+12
i2c_smbus_read_block_data() returns negative errno else the number of data bytes in the slave's response. Checking for error not null means the function always fails if the device answers properly. So given that we read 3 bytes and access those, better check that we actually read those 3 bytes.

2016-10-03Input: ektf2127 - mark PM functions as __maybe_unusedArnd Bergmann1-2/+2
The newly added ektf2127 driver uses the SIMPLE_DEV_PM_OPS macro to conditionally refer to the resume/suspend functions, which causes a warning when CONFIG_PM_SLEEP is disabled: drivers/input/touchscreen/ektf2127.c:168:12: error: 'ektf2127_resume' defined but not used [-Werror=unused-function] drivers/input/touchscreen/ektf2127.c:156:12: error: 'ektf2127_suspend' defined but not used [-Werror=unused-function] We could either put these functions inside of an #ifdef or add __maybe_unused annotations. This uses the second approach, which is generally more foolproof.

2016-09-21Input: serio - add hangup supportHans Verkuil1-3/+14
The Pulse-Eight USB CEC adapter is a usb device that shows up as a ttyACM0 device. It requires that you run inputattach in order to communicate with it via serio. This all works well, but it would be nice to have a udev rule to automatically start inputattach. That too works OK, but the problem comes when the USB device is unplugged: the tty hangup is never handled by the serio framework so the inputattach utility never exits and you have to kill it manually. By adding this hangup callback the inputattach utility now properly exits as soon as the USB device is unplugged. The udev rule I used on my Debian sid system is: SUBSYSTEM=="tty", KERNEL=="ttyACM[0-9]*", ATTRS{idVendor}=="2548", ATTRS{idProduct}=="1002", ACTION=="add", TAG+="systemd", ENV{SYSTEMD_WANTS}+="pulse8-cec-inputattach@%k.service" And /etc/systemd/system/[email protected] is as follows: =============================================================== [Unit] Description=inputattach for pulse8-cec device on %I [Service] Type=simple ExecStart=/usr/local/bin/inputattach --pulse8-cec /dev/%I KillMode=process =============================================================== Signed-off-by: Hans Verkuil <[email protected]> Tested-by: Hans Verkuil <[email protected]> Signed-off-by: Dmitry Torokhov <[email protected]>

The power button found in tps65217 device is very similar to the tps65218, so let's enhance the driver to support both variants. This driver enables us to use tps65217's power button as KEY_POWER on am335x boards (directly connected button in chiliboard, accessible pin via expansion header in beaglebone).

2016-09-05Input: gpio-keys-polled - don't use unit-address with button nodesVladimir Zapolskiy1-3/+2
The change corrects an example in device tree documentation section, because button/key device nodes don't contain reg property there is no need to declare unit-address, and address and size cell properties are also redundant. At the moment a compilation of the hypothetical original example should produce W=1 level warnings, and it is better to stop spreading misusage of the polled gpio keys device tree binding through this example.

2016-08-29Input: add generic input driver to read encoded GPIO linesVignesh R4-0/+173
Add a driver to read group of GPIO lines and provide its status as a numerical value as input event to the system. This will help in interfacing devices, that can be connected over GPIOs, that provide input to the system by driving GPIO lines connected to them like a rotary dial or a switch. For example, a rotary switch can be connected to four GPIO lines. The status of the GPIO lines reflect the actual position of the rotary switch dial. For example, if dial points to 9, then the four GPIO lines connected to the switch will read HLLH(0b'1001 = 9). This value can be reported as an ABS_* event to the input subsystem.

2016-08-25Input: wm97xx - remove deprecated create_singletheread_workqueueBhaktipriya Shridhar1-1/+1
alloc_ordered_workqueue() replaces deprecated create_singlethread_workqueue(). It queues work items via &wm->ts_reader and &wm->pen_event_work which map to wm97xx_pen_irq_worker (handles a pen down interrupt) and wm97xx_ts_reader (the touchscreen sample reader) respectively. Hence, an ordered dedicated workqueue has been used.

2016-08-25Input: mc13783_ts - remove deprecated create_singletheread_workqueueBhaktipriya Shridhar1-17/+7
The workqueue "workqueue" has a single workitem(&priv->work) and hence doesn't require ordering. Also, it is not being used on a memory reclaim path. Hence, the singlethreaded workqueue has been replaced with the use of system_wq. System workqueues have been able to handle high level of concurrency for a long time now and hence it's not required to have a singlethreaded workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue created with create_singlethread_workqueue(), system_wq allows multiple work items to overlap executions even on the same CPU; however, a per-cpu workqueue doesn't have any CPU locality or global ordering guarantee unless the target CPU is explicitly specified and thus the increase of local concurrency shouldn't make any difference. Workitem is sync cancelled in mc13783_ts_remove() to ensure that there are no workitems pending when the driver is disconnected.

There are multiple work items on the work queue viz &priv->dev3_register_work, &priv->recalib_wq, &psmouse->resync_work, which require execution ordering. Hence, an ordered workqueue has been used. The workqueue is not being used on a memory reclaim path. Hence, WQ_MEM_RECLAIM has not been set.
