drivers/input: Add module.h to modular drivers implicitly using it

2011-10-31T23:31:16Z

A pending cleanup will mean that module.h won't be implicitly everywhere anymore. Make sure the modular drivers in input dir are actually calling out for explicitly in advance. Signed-off-by: Paul Gortmaker

Input: ad7879 - fix deficient device disable

2011-08-03T05:17:44Z

Input close or device disable should not interact with the exported gpiolib functionality. However that's the case. __ad7879_disable() clears the entire AD7879_REG_CTRL2, while it should just power down the ADC and its reference. Signed-off-by: Michael Hennerich Signed-off-by: Dmitry Torokhov

Input: ad7879 - prevent invalid finger data reports

2010-10-29T05:32:50Z

Considering following scenario - the touch is present on the screen at the beginning of the last conversion sequence, but by the time the last sequence is finished, the finger is lift off. The AD7879 data available interrupt signals (DAV) completion, however some X,Y values are not valid because the screen inputs were floating during the acquisition. The AD7877 acts differently here, since it only asserts DAV if the touch is still present when the conversion sequence finished. Based on the fact that this can only happen in the last sample of the repeated conversion sequence, we simply skip the last (short glitches are filtered by the AD7879 internal median and average filters). This doesn't cause noticeable side effects, since the minimum conversion interval is 9.44ms. We receive ~100 waypoint samples per second, so we simply delay the result by 9.44ms. We also reject samples where pressure is greater than pressure_max. Signed-off-by: Michael Hennerich Signed-off-by: Dmitry Torokhov

Input: ad7879 - report EV_KEY/BTN_TOUCH events

2010-07-03T20:13:20Z

Some input events users such as Android require BTN_TOUCH events. Implement EV_KEY/BTN_TOUCH and make sure that the release event is not erroneous scheduled without a preceding valid touch. Avoid duplicated BTN_TOUCH events, even though input core filters them. Signed-off-by: Michael Hennerich Signed-off-by: Dmitry Torokhov

Input: ad7879 - split bus logic out

2010-07-03T20:13:03Z

The ad7879 driver is using the old bus method of only supporting one at a time (I2C or SPI). So refactor it like the other input drivers that support multiple busses simultaneously. Signed-off-by: Mike Frysinger Signed-off-by: Michael Hennerich Signed-off-by: Dmitry Torokhov

i2c: Remove all i2c_set_clientdata(client, NULL) in drivers

2010-06-03T09:33:58Z

I2C drivers can use the clientdata-pointer to point to private data. As I2C devices are not really unregistered, but merely detached from their driver, it used to be the drivers obligation to clear this pointer during remove() or a failed probe(). As a couple of drivers forgot to do this, it was agreed that it was cleaner if the i2c-core does this clearance when appropriate, as there is no guarantee for the lifetime of the clientdata-pointer after remove() anyhow. This feature was added to the core with commit e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers. As there is no need anymore to clear the clientdata-pointer, remove all current occurrences in the drivers to simplify the code and prevent confusion.

Input: ad7879 - support auxiliary GPIOs via gpiolib

Drop the simple fancy sysfs hooks for the aux GPIOs and expose these via the gpiolib interface so that other drivers can use them. Signed-off-by: Michael Hennerich Signed-off-by: Mike Frysinger Signed-off-by: Dmitry Torokhov
