litmus-rt-tegra.git/drivers/media/rc, branch master

Patched in Tegra support.

Drivers: media: remove __dev* attributes.

2013-01-03T23:57:02+00:00

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Merge branch 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

2012-12-14T03:22:22+00:00

Pull media updates from Mauro Carvalho Chehab:

 - Missing MAINTAINERS entries were added for several drivers

 - Adds V4L2 support for DMABUF handling, allowing zero-copy buffer
   sharing between V4L2 devices and GPU

 - Got rid of all warnings when compiling with W=1 on x86

 - Add a new driver for Exynos hardware (s3c-camif)

 - Several bug fixes, cleanups and driver improvements

[media] winbond-cir: add carrier detection

2012-11-21T19:06:17+00:00

The winbond hardware has a counter for leading edges, which increases as
they are received. As we read raw IR from a fifo in an interrupt handler,
we cannot correlate them to specific IR pulses so we simply count all
pulses and edges until we go idle and disable the receiver.

[media] winbond-cir: fix idle mode

2012-11-21T19:03:30+00:00

The receiver is never disabled by idle mode since rxstate never gets set
to RXSTATE_ACTIVE, so we keep on getting interrupts after the first IR
activity ends. Note that ir_raw_event_reset() already calls
ir_raw_event_handle().

[media] ene-ir: Fix cleanup on probe failure

2012-10-28T18:28:58+00:00

This makes the cleanup on probe failure more consistent with other
drivers. This is similar to what commit
f27b853ea24a9b70585f9251384d97929e6551c3 ("[media] rc: Fix invalid
free_region and/or free_irq on probe failure") did for some other
drivers.
In addition to making the cleanup more consistent, this also fixes a
case where (on a ene_hw_detect failure) free_region would be called on a
region that was not requested yet.
This last problem was probably introduced by the moving of code in
commit b31b021988fed9e3741a46918f14ba9b063811db ("[media] ene_ir: Fix
driver initialisation") and commit
9ef449c6b31bb6a8e6dedc24de475a3b8c79be20 ("[media] rc: Postpone ISR
registration").

[media] nuvoton-cir: carrier detect support is broken - remove it

2012-10-27T20:10:07+00:00

The carrier detect return value is never used on nuvoton driver:
drivers/media/rc/nuvoton-cir.c: In function 'nvt_process_rx_ir_data':
drivers/media/rc/nuvoton-cir.c:623:6: warning: variable 'carrier' set but not used [-Wunused-but-set-variable]
Also, this would be called only if a boolean variable is enabled,
but there's no condition that enables it inside the driver. So,
comment the carrier detection code, as it might be useful later,
and remove the unused glue code.
