alignment, fixed_phy_vdd and phy_enable fields are now unused
so removed them. The data alignment is now derived directly
from media bus pixel code, phy_enable callback has been replaced
with direct function call and fixed_phy_vdd was dropped in commit

vpif_display relied on a 1-1 mapping of output and subdev. This is not
necessarily the case. Separate the two. So there is a list of subdevs
and a list of outputs. Each output refers to a subdev and has routing
information. An output does not have to have a subdev.
The initial output for each channel is set to the fist output.
Currently missing is support for associating multiple subdevs with
an output.Signed-off-by: Lad, Prabhakar

Add subdev callbacks for setting up parameters of the frame on media bus
that are not exposed to user space directly. This is just an initial,
mostly stub implementation. struct v4l2_mbus_frame_desc is intended
to be extended with sub-structures specific to a particular hardware media
bus. For now these new callbacks are used only to query or specify maximum
size of a compressed or hybrid (container) media bus frame in octets.Signed-off-by: Sylwester Nawrocki

The s_rx_buffer callback allows the host to set buffer for a data being
received by the subdev, e.g. non-image frame (meta) data. This callback
can be implemented by subdevice like a MIPI CSI2 receiver, allowing the
host driver to gather additional data into frame buffer passed to user
space.Signed-off-by: Sylwester Nawrocki

In order to reuse the FIMC-LITE module on Exynos4 and Exynos5
SoC introduce a set of callbacks for the media pipeline control
from within FIMC/FIMC-LITE video node. It lets us avoid symbol
dependencies between FIMC-LITE and the whole media device driver,
which simplifies the initialization sequences and doesn't
introduce issues preventing common kernel image for exynos4 and
exynos5 SoCs.
This patch also corrects following build errors:
drivers/built-in.o: In function `buffer_queue':
drivers/media/video/s5p-fimc/fimc-lite.c:414: undefined reference
to `fimc_pipeline_s_stream'
drivers/built-in.o: In function `fimc_lite_resume':

to `fimc_pipeline_shutdown'

CONFIG_VIDEO_S5P_FIMC.Reported-by: Sachin Kamat

With a filter function you can control more precisely which controls
are added. This is useful in particular for radio device nodes for
combined TV/Radio cards where you want to show just the radio-specific
controls and not controls like brightness.Signed-off-by: Hans Verkuil

This replaces BUG_ON() calls with WARN_ON(), and returns
EINVAL if some parameter is NULL, as suggested by Jonathan and Mauro.
The BUG_ON() call is too drastic to be used in this case.

Initial version of this driver.
The full datasheets are available from the Analog Devices website:
http://ez.analog.com/docs/DOC-1741
Not all features of the receiver are supported by this driver for various
reasons. Most notably:- No CEC support (the CEC API needs a lot more discussion)
- No HDCP repeater support (we don't use that either)I'm sure that there are more things missing, but this driver does work
well for our hardware.Note that I am using the register addresses instead of register names: the
datasheet containing the register descriptions is organized by register
address. Using names would make the datasheet lookup very hard. An attempt
was made to try and document what is being done when registers are used
instead.Signed-off-by: Hans Verkuil

reasons. Most notably:- No CEC support (the CEC API needs a lot more discussion)
- Only port A of the four HDMI input ports is implemented (our hardware only
uses that port)
- No HDCP repeater support (we don't use that either)And since there are some 600-odd pages of datasheet for this single device,
I'm sure that there are many more things missing, but this driver does work

These two helper functions detect whether the analog video timings detected
by the video receiver match the VESA CVT or GTF standards.They basically do the inverse of the CVT and GTF modeline calculations.
This patch also adds a helper function that will determine the aspect ratio

helper function.Signed-off-by: Hans Verkuil

Instead of forcing all soc-camera drivers to go through the mid-layer to
handle power management, create soc_camera_power_[on|off]() functions
that can be called from the subdev .s_power() operation to manage
regulators and platform-specific power handling. This allows non
soc-camera hosts to use soc-camera-aware clients.Signed-off-by: Laurent Pinchart

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.Signed-off-by: Timo Kokkonen

This callback were meant to allow overriding a FE callback, before its
call, but it is not really needed, as the callback can be intercepted
after tuner attachment.Worse than that, only DVBv3 calls are intercepted this way, so a DVBv5
application will produce different effects than a DVBv3 one.So, get rid of it.
