docs: Fix some broken references

2018-06-15T21:10:01Z

As we move stuff around, some doc references are broken. Fix some of them via this script: ./scripts/documentation-file-ref-check --fix Manually checked if the produced result is valid, removing a few false-positives.

Input: ti_am335x_tsc - prevent system suspend when TSC is in use

2018-05-30T23:42:12Z

Prevent system suspend while user has finger on touch screen, because TSC is wakeup source and suspending device while in use will result in failure to disable the module. This patch uses pm_stay_awake() and pm_relax() APIs to prevent and resume system suspend as required. Signed-off-by: Grygorii Strashko Signed-off-by: Vignesh R Signed-off-by: Dmitry Torokhov

Input: ti_am335x_tsc - ack pending IRQs at probe and before suspend

2018-05-30T23:42:12Z

It is seen that just enabling the TSC module triggers a HW_PEN IRQ without any interaction with touchscreen by user. This results in first suspend/resume sequence to fail as system immediately wakes up from suspend as soon as HW_PEN IRQ is enabled in suspend handler due to the pending IRQ. Therefore clear all IRQs at probe and also in suspend callback for sanity. Signed-off-by: Grygorii Strashko Signed-off-by: Vignesh R Signed-off-by: Dmitry Torokhov

Input: atmel_mxt_ts - fix reset-gpio for level based irqs

2018-05-24T16:56:47Z

The current reset-gpio support triggers an interrupt storm on platforms using the maxtouch with level based interrupt. The Motorola Droid 4, which I used for some of the tests is not affected, since it uses a edge based interrupt. This change avoids the interrupt storm by enabling the device while its interrupt is disabled. Afterwards we wait 100ms. This is important for two reasons: The device is unresponsive for some time (~22ms for mxt224E) and the CHG (interrupt) line is not working properly for 100ms. We don't need to wait for any following interrupts, since the following mxt_initialize() checks for bootloader mode anyways. This fixes a boot issue on GE PPD (watchdog kills device due to interrupt storm) and does not cause regression on Motorola Droid 4.

Input: atmel_mxt_ts - require device properties present when probing

2018-05-24T16:31:39Z

The driver needs help determining whether it is dealing with a touchscreen or a touchpad, and with button mapping. Previously we supported passing this data via device properties, and also had DMI lists for Chromebooks that specified Atmel devices in ACPI, but did not provide enough data there. Now that chromeos_laptop driver is adjusted to supply necessary device properties even for ACPI devices, we can drop the DMI tables and refuse to probe if device properties are not attached to the device. We use presence of "compatible" property to determine if device properties are attached to the device or not and rely on chromeos_laptop to re-probe the device after attaching missing device properties to it.

Input: add support for ChipOne icn8505 based touchscreens

2018-05-09T20:29:35Z

The ChipOne icn8505 is an i2c capacitive touchscreen controller typically used in cheap x86 tablets, this commit adds a driver for it. Note the icn8505 is somewhat similar to the icn8318 and I started with modifying that driver to support both, but in the end the differences were too large and I decided to write a new driver instead.
