Get rid of the attb_read_val() platform hook. Instead, read the ATTB gpio directly from the driver. Fail if valid ATTB gpio is not provided by patform data.

2014-05-18Input: pixcir_i2c_ts - initialize interrupt mode and power modeRoger Quadros2-8/+216
Introduce helper functions to configure power and interrupt registers. Default to IDLE mode on probe as device supports auto wakeup to ACVIE mode on detecting finger touch. Configure interrupt mode and polarity on start up. Power down on device closure or module removal.

2014-05-14Input: wacom - add support for three new ISDv4 sensorsJason Gerecke3-1/+41
This patch adds support for the 0x4004, 0x5000, and 0x5002 sensors found on what should be the Motion R12, Fujitsu Q704, and Fujitsu T904. These tablets use a new report ID (3) for their touch packets and a slightly different HID descriptor format, but are otherwise largely identical in protocol to the "MTTPC" tablets. Note: * The R12 uses its 0x4004 sensor for touch input only. A pen interface is not present in its HID descriptor, though its possible a 0x4004 may be used for pen input by other tablet PCs in the future. * The 0x5002 sensor appears to use a new report ID (8) for its pen packets. The other sensors continue to use the traditional report ID (2).

2014-05-14Input: pmic8xxx-pwrkey - set sane default for debounce timeStephen Boyd1-4/+4
If the debounce time is 0 our usage of ilog2() later on in this driver will cause undefined behavior. If CONFIG_OF=n this fact is evident to the compiler, and it emits a call to ____ilog2_NaN() which doesn't exist. Fix this by setting a sane default for debounce and failing to probe if debounce is 0 in the DT.

2014-05-14Input: 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.

2014-05-14Input: 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.

Managed resources are becoming more and more popular in drivers. Let's implement managed polled input devices, to complement managed regular input devices.

2014-05-14Input: 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.

2014-05-12Input: fix ps2/serio module dependencyArnd Bergmann2-2/+2
The ps2 mouse and keyboard drivers use the "serio" framework that they correctly select in Kconfig, and that in turn depends on the i8042 driver, which is also allowed to be disabled for architectures that don't have an i8042. However, Kconfig also allows i8042 to be built as a module while the serio framework is built-in, which causes this link error: drivers/built-in.o: In function `ps2_begin_command': :(.text+0x26b6cc): undefined reference to `i8042_check_port_owner' :(.text+0x26b6d4): undefined reference to `i8042_lock_chip' drivers/built-in.o: In function `ps2_end_command': :(.text+0x26b734): undefined reference to `i8042_check_port_owner' :(.text+0x26b73c): undefined reference to `i8042_unlock_chip' On x86, a specific 'select SERIO_I8042' takes care of it, but not on the other architecture that potentially have a i8042. This patch changes the Kconfig logic to ensure that whenever there is an i8042, it does get used for the serio driver, avoiding the link error above.
