Input: delete non-required instances of include

2014-01-07T07:23:57+00:00

None of these files are actually using any __init type directives and hence don't need to include . Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next. Signed-off-by: Paul Gortmaker Signed-off-by: Dmitry Torokhov

Input: use dev_get_platdata()

2013-12-06T10:06:29+00:00

Use the wrapper function for retrieving the platform data instead of accessing dev->platform_data directly. This is a cosmetic change to make the code simpler and enhance the readability. Signed-off-by: Jingoo Han Acked-by: Fugang Duan Signed-off-by: Dmitry Torokhov

Input: request threaded-only IRQs with IRQF_ONESHOT

2012-07-04T20:12:19+00:00

Since commit 1c6c69525b ("genirq: Reject bogus threaded irq requests") threaded IRQs without a primary handler need to be requested with IRQF_ONESHOT, otherwise the request will fail. This patch adds the IRQF_ONESHOT to input drivers where it is missing. Not modified by this patch are those drivers where the requested IRQ will always be a nested IRQ (e.g. because it's part of an MFD), since for this special case IRQF_ONESHOT is not required to be specified when requesting the IRQ.

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

2011-10-31T23:31:16+00:00

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: ad714x - read the interrupt status registers in a row

2011-08-22T16:59:26+00:00

The interrupt status registers should be read in row to avoid invalid data. Alter "read" method for both bus options to allow reading several registers in a row and make sure we read interrupt status registers properly. Read sequence saves 50% of bus transactions compared to single register reads. So use it also for the result registers, which are also located in a row. Also update copyright notice.

Input: ad714x - use DMA-safe buffers for spi_write()

2011-08-22T16:59:20+00:00

spi_write() requires use of DMA-safe (cacheline aligned) buffers. Also use the same buffers when reading data since to avoid extra locking and potential memory allocation in spi_write_then_read(). Acked-by: Michael Hennerich Signed-off-by: Dmitry Torokhov

Input: ad714x - fix captouch wheel option algorithm

2011-05-17T06:20:17+00:00

As reported by Jean-Francois Dagenais, the wheel algorithm caused a divide by zero exception due to missing variable pre-initialization. In fact it turned out that the whole algorithm had several problems. It is therefore replaced with something that is known working.

Input: ad714x - allow platform code to specify irqflags

2011-05-17T06:20:13+00:00

Add option to specify irqflags in platfrom data. Also update copyright notice. Signed-off-by: Michael Hennerich Tested-by: Jean-Francois Dagenais Signed-off-by: Dmitry Torokhov

Input: ad714x - fix threshold and completion interrupt masks

2011-05-17T06:20:09+00:00

Fix two issues in the threshold and completion interrupt mask and unmask functions. According to the AD714x datasheets the highest stage completion interrupt should be enabled. Fix mask computation. Signed-off-by: Michael Hennerich Tested-by: Jean-Francois Dagenais Signed-off-by: Dmitry Torokhov

Input: ad714x - fix up input configuration

2011-05-17T06:20:04+00:00

Add missing input name and set up parent devices so input devices will show in proper places in sysfs tree. Signed-off-by: Michael Hennerich Tested-by: Jean-Francois Dagenais Signed-off-by: Dmitry Torokhov
