Tony Lindgren 44773ba170 ARM: OMAP2+: Drop unused pm-noop
Looks like these functions don't do anything in the mainline kernel so
we can just drop it.

Note that we must now also remove ir-rx51 pdata as it relies on the dummy
platform data that does not do anything. And ir-rx51 is calling a pdata
callback that doesn't do anything without checking if it exists first.

For configuring device specific minimal latencies, the interface to use
is pm_qos_add_request(). For an example, see what was done in commit
9834ffd1ec ("ASoC: omap-mcbsp: Add PM QoS support for McBSP to prevent
glitches"). I've added some comments to ir-rx51 so people using it can
add pm_qos support and test it.

Sean Young a92def1bec [media] ir-rx51: port to rc-core
This driver was written using lirc since rc-core did not support
transmitter-only hardware at that time. Now that it does, port
this driver.

Compile tested only.

Thomas Gleixner 2456e85535 ktime: Get rid of the union
ktime is a union because the initial implementation stored the time in
scalar nanoseconds on 64 bit machine and in a endianess optimized timespec
variant for 32bit machines. The Y2038 cleanup removed the timespec variant
and switched everything to scalar nanoseconds. The union remained, but
become completely pointless.

Get rid of the union and just keep ktime_t as simple typedef of type s64.

The conversion was done with coccinelle and some manual mopping up.

Ivaylo Dimitrov 79cdad3635 ir-rx51: use hrtimer instead of dmtimer
Drop dmtimer usage for pulse timer in favor of hrtimer. That allows
removing PWM dmitimer platform data usage.

Ivaylo Dimitrov b540617698 ir-rx51: add DT support to driver
With the upcoming removal of legacy boot, lets add support to one of the
last N900 drivers remaining without it. As the driver still uses omap
dmtimer, add auxdata as well.

Ivaylo Dimitrov 4406d52a0b ir-rx51: Fix build after multiarch changes broke it
The ir-rx51 driver for n900 has been disabled since the multiarch
changes as plat include directory no longer is SoC specific.

Let's fix it with minimal changes to pass the dmtimer calls in
pdata. Then the following changes can be done while things can
be tested to be working for each change:

1. Change the non-pwm dmtimer to use just hrtimer if possible

2. Change the pwm dmtimer to use Linux PWM API with the new
   drivers/pwm/pwm-omap-dmtimer.c and remove the direct calls
   to dmtimer functions

3. Parse configuration from device tree and drop the pdata

Mauro Carvalho Chehab eb4b0ec75e [media] include/media: move platform_data to linux/platform_data/media
Let's not mix platform_data headers with the core headers. Instead, let's
create a subdir at linux/platform_data and move the headers to that
common place, adding it to MAINTAINERS.

The headers were moved with:
	mkdir include/linux/platform_data/media/; git mv include/media/gpio-ir-recv.h include/media/ir-rx51.h include/media/mmp-camera.h include/media/omap1_camera.h include/media/omap4iss.h include/media/s5p_hdmi.h include/media/si4713.h include/media/sii9234.h include/media/smiapp.h include/media/soc_camera.h include/media/soc_camera_platform.h include/media/timb_radio.h include/media/timb_video.h include/linux/platform_data/media/

And the references fixed with this script:
    MAIN_DIR="linux/platform_data/"
    PREV_DIR="media/"
    DIRS="media/"

    echo "Checking affected files" >&2
    for i in $DIRS; do
	for j in $(find include/$MAIN_DIR/$i -type f -name '*.h'); do
		 n=`basename $j`
		git grep -l $n
	done
    done|sort|uniq >files && (
	echo "Handling files..." >&2;
	echo "for i in \$(cat files|grep -v Documentation); do cat \$i | \\";
	(
		cd include/$MAIN_DIR;
		for j in $DIRS; do
			for i in $(ls $j); do
				echo "perl -ne 's,(include [\\\"\\<])$PREV_DIR($i)([\\\"\\>]),\1$MAIN_DIR$j\2\3,; print \$_' |\\";
			done;
		done;
		echo "cat > a && mv a \$i; done";
	);
	echo "Handling documentation..." >&2;
	echo "for i in MAINTAINERS \$(cat files); do cat \$i | \\";
	(
		cd include/$MAIN_DIR;
		for j in $DIRS; do
			for i in $(ls $j); do
				echo "  perl -ne 's,include/$PREV_DIR($i)\b,include/$MAIN_DIR$j\1,; print \$_' |\\";
			done;
		done;
		echo "cat > a && mv a \$i; done"
	);
    ) >script && . ./script

Dmitry Torokhov bf30690029 [media] Media: remove incorrect __init/__exit markups
Even if bus is not hot-pluggable, the devices can be unbound from the
driver via sysfs, so we should not be using __exit annotations on
remove() methods. The only exception is drivers registered with
platform_driver_probe() which specifically disables sysfs bind/unbind
attributes.
Similarly probe() methods should not be marked __init unless
platform_driver_probe() is used.

Greg Kroah-Hartman 4c62e9764a Drivers: media: remove __dev* attributes.
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.

Timo Kokkonen c332e8472d [media] media: rc: Introduce RX51 IR transmitter driver
This is the driver for the IR transmitter diode found on the Nokia
N900 (also known as RX51) device. The driver is mostly the same as
found in the original 2.6.28 based kernel that comes with the device.

The following modifications have been made compared to the original
driver version:

- Adopt to the changes that has happen in the kernel during the past
  five years, such as the change in the include paths

- The OMAP DM-timers require much more care nowadays. The timers need
  to be enabled and disabled or otherwise many actions fail. Timers
  must not be freed without first stopping them or otherwise the timer
  cannot be requested again.

The code has been tested with sending IR codes with N900 device
running Debian userland. The device receiving the codes was Anysee
DVB-C USB receiver.
