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.

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().

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 - 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.
