| * | | | Input: atmel_mxt_ts - move input device init into separate functionNick Dyer2014-07-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is useful to initialise the input device later: - Screen parameters may not be not known yet, for instance if waiting for firmware loader to return. - Device may be in bootloader mode on probe (but could still be recovered by firmware download). In addition, later devices have a different touchscreen object (T100) which requires handling differently. This also reduces the complexity of the probe function.

Therefore set up the interrupt handler earlier. However, this introduces states where parts of the interrupt processing must not run. Use data->object_table as a way to tell whether the chip information is valid, and data->input_dev as a way to tell whether it is valid to generate input report.

This change replaces the msleep with a wait for completion that the mxt_interrupt handler signals. Also add CHG poll after last firmware frame - some bootloader versions will assert the interrupt line after the final frame, in testing this meant that the driver attempts to read the info block too early whilst the chip is still resetting.

In addition, different versions of maXTouch chips may have these values in different places or may not even have them at all.

| | * | | PM / QoS: Add type to dev_pm_qos_add_ancestor_request() argumentsRafael J. Wysocki2014-02-10

That will allow the drivers of devices without latency tolerance hardware support to use their ancestors having it as proxies for their latency tolerance requirements. Signed-off-by: Rafael J.

| * | | | Input: sun4i-ts - add support for temperature sensorHans de Goede2014-05-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sun4i resisitive touchscreen controller also comes with a built-in temperature sensor. This commit adds support for it. This commit also introduces a new "ts-attached" device-tree property, when this is not set, the input part of the driver won't register. This way the internal temperature sensor can be used to measure the SoC temperature independent of there actually being a touchscreen attached to the controller.

| * | | | Input: add driver for Allwinner sunxi SoC's rtp controllerHans de Goede2014-05-14

The original android driver contains some complicated heuristics using the aprox. distance between the 2 touches to see if the user is making a pinch open / close movement, and then reports emulated multi-touch events around the last touch coordinate (as the dual-touch coordinates are worthless). These kinds of heuristics are just asking for trouble (and don't belong in the kernel). So this driver offers straight forward, reliable single touch functionality only.
