This patch adds definition of additional color effects:
- V4L2_COLORFX_AQUA,
- V4L2_COLORFX_ART_FREEZE,
- V4L2_COLORFX_SILHOUETTE,
- V4L2_COLORFX_SOLARIZATION,
- V4L2_COLORFX_ANTIQUE,
- V4L2_COLORFX_ARBITRARY_CBCR.
The control's type in the documentation is changed from 'enum' to 'menu'
- V4L2_CID_COLORFX has always been a menu, not an integer type control.
The V4L2_COLORFX_ARBITRARY_CBCR option enables custom color effects,
which are impossible or impractical to define as menu items. The
V4L2_CID_BLUE_BALANCE and V4L2_CID_RED_BALANCE controls allow in this
case to configure the Cb, Cr coefficients.

So this just hijacks the RED/BLUE_BALANCE controls for a different purpose?
If I understand this 'effect' correctly it just replaces the Cb and Cr
coefficients with fixed values, basically giving you a B&W picture (the Y
coefficient), except that it is really a 'Black&FixedColor' picture.
I think you should add a new control for setting this. V4L2_CID_COLORFX_COLOR
or something.
Regards,
Hans

Uh, the meaning is indeed a bit different. Probably not a good idea to reuse
the controls like this in the standard API.

Yes, this is also my understanding. The TRMs are not very verbose about it,
but I think it is exactly how it works. The effect is similar to looking
through a coloured glass, where colour changes from green through red to violet
when changing the (CR, CB) coefficients gradually from (0, 0) -> (0, 255) ->
(255, 255).

Do you mean something similar to V4L2_CID_BG_COLOR ? When a different colour
space is used then the range for those Cb, Cr components changes. It can be
0...255 or 16...240. So best would be to have 2 controls, for reporting min/max
to the user.
Maybe it would be better to add a V4L2_COLORFX_COLOR menu entry and
V4L2_CID_COLORFX_CB, V4L2_CID_COLORFX_CR controls ?

Virtually no functional changes, just code reordering. This let us to
clearly separate all logical functions available in the driver: fimc
capture, mem-to-mem, and later fimc-lite capture, ISP features, etc.

Remove num_entities from the driver data structure as this information
is already there as the variant array's length. Remove the 'samsung_'
prefix from some data structures since it doesn't really carry any
useful information and makes the names unnecessarily long.

In order to be able to select only FIMC-LITE support, which is added
with subsequent patches, the regular FIMC support is now contained
only in fimc-core.c, fimc-m2m.c and fimc-capture.c files. The graph
and pipeline management is now solely handled in fimc-mdevice.[ch].
This means the FIMC driver can now be excluded with Kconfig option,
leaving only FIMC-LITE and allowing this driver to be reused in SoCs
that have only FIMC-LITE and no regular FIMC IP.

Simplify the register API and use FIMC_REG_ prefix for all register
definitions for consistency with FIMC-LITE. The unused image effect
defines are removed.

There is getting more entities to manage within single video pipeline
in newer SoCs. To simplify code put subdevs' pointer into an array
rather than adding new member in struct fimc_pipeline for each subdev.
This allows to easier handle subdev operations in proper order.
Additionally walk graph in one direction only in fimc_pipeline_prepare()
function to make sure we properly gather only media entities that below
to single data pipeline. This avoids wrong initialization in case where,
for example there are multiple active links from s5p-mipi-csis subdev
output pad.
struct fimc_pipeline declaration is moved to the driver's public header
to allow other drivers to reuse the fimc-lite driver added in subsequent
patches.

Prefix the pixel format enumerations with FIMC_FMT_ to make it more clear,
especially when used in new IP drivers, like fimc-lite, etc. Also add IO_
prefix in the input/output enumeration.

This patch adds driver for FIMC-LITE camera host interface. This new IP
differs from the regular FIMC IP in that it doesn't have input DMA,
scaler and color space conversion support. So it just plain camera host
interface for MIPI-CSI2 and ITU-R interfaces. For the serial bus support
it interworks with MIPI-CSIS and the exisiting s5p-csis driver.
The FIMC-LITE and MIPI-CSIS drivers can also be reused in the Exynos5
SoC series.
