2014-05-15Input: sun4i-ts - add support for temperature sensorHans de Goede3-31/+114
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.

2014-05-15Input: add driver for Allwinner sunxi SoC's rtp controllerHans de Goede4-0/+288
Note the sun4i-ts controller is capable of detecting a second touch, but when a second touch is present then the accuracy becomes so bad the reported touch location is not useable. 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.

2014-05-15Input: implement managed polled input devicesDmitry Torokhov2-2/+119
Managed resources are becoming more and more popular in drivers. Let's implement managed polled input devices, to complement managed regular input devices. Similarly to managed regular input devices only one new call devm_input_allocate_polled_device() is added and the rest of APIs is modified to work with both managed and non-managed devices.

2014-05-15Input: remove race when instantiating polled device attributesDmitry Torokhov1-10/+9
Polled device's attributes controlling polling rate and whether polling is enabled are attached to input device. We should have device core instantiate them for us, so that they are created by the time new device notification is sent to userspace, instead of doing it ourselves afterwards.

2014-05-15Input: ads7877 - remove bitrotted commentMark Brown1-5/+0
While searching for users of spi_async() I found a reference in the ad7877 driver to using it to initiate data transfer from the interrupt handler. However there is no code for this, instead the interrupt handler is a threaded handler and uses spi_sync() instead. Remove the bitrotted comment, though in actual fact the use case mentioned is a great use for spi_async() since it would cut down on latency handling the interrupt by saving us a context switch before we start SPI. This was previously implemented, it was removed in commit b534422b2d11 (Input: ad7877 - switch to using threaded IRQ) for code complexity reasons. It may be better to revert that commit instead.
