The various data structures that describe the components of the camera
access layer (CAL) are named without much consistency. Start cleaning
this up by renaming the structure that describes the CAMERARX block,
cc_data, to cal_camerarx.

cff3784dfa media: ti-vpe: cal: Decouple CSI2 port and CPORT
The CPORT mentioned in the CAL documentation has nothing to do with the
CSI-2 ports. It's a remnant of CSI-3 support (or an attempt to achieve
it), and now only serves as an arbitraty tag value used to associate
data samples with contexts. Add a cport field to the cal_ctx structure
and use it instead of the CSI-2 port number where a CPORT is required by
the hardware. The value of the cport field is currently the same as the
csi2_port field, so there's no functional change, but this will help
reworking CPORT and CSI-2 port handling separately.

2e7ee8bb24 media: atmel: atmel-isc: rework component offsets
The component offsets were computed in a negative way: they were
subtracted from the actual color component value.
So, a higher offset was reducing the component value.
This is not really desirable, as the offset is a 2's complements
number with 1 bit for sign and 12 value bits, so we would like to be able
to also add to the component, not only subtract.
The reported number in v4l2 is fine, a range from -4095 to +4095.
However when configuring a negative value for the offset, this would in
fact not function, because with the old code, the number was subtracted
from the max value. By setting something negative, it was overflowing in
fact. Reworked the component offsets by placing the real value as the
v4l2 ctrls.

Now, the values are the real number that is added or subtracted from
the component.
The negative values received from v4l2 are already in 2's complements, so
there is no need for conversion.
This actually simplifies a lot the computation procedure, eliminating the
need for the macros that convert from v4l2 values to ISC values and
viceversa.
Also the ZERO_VAL is eliminated, as 0 is now 0, as it's supposed to be.

Example after this change:

 # v4l2-ctl --set-ctrl=red_component_offset=-150 -L

Adapt the logic to only set the output CSC mode when the output is YUV and
the input is RGB. Also add a comment to clarify the rationale.

ded874ece2 media: rockchip: rga: Introduce color fmt macros and refactor CSC mode logic
This introduces two macros: RGA_COLOR_FMT_IS_YUV and RGA_COLOR_FMT_IS_RGB
which allow quick checking of the colorspace familily of a RGA color format.

These macros are then used to refactor the logic for CSC mode selection.
The two nested tests for input colorspace are simplified into a single one,
with a logical and, making the whole more readable.

Fix up inconsistent usage of upper and lowercase letters in "Samsung"
and "Exynos" names.

"SAMSUNG" and "EXYNOS" are not abbreviations but regular trademarked
names.  Therefore they should be written with lowercase letters starting
with capital letter.

The lowercase "Exynos" name is promoted by its manufacturer Samsung
Electronics Co., Ltd., in advertisement materials and on website.

Although advertisement materials usually use uppercase "SAMSUNG", the
lowercase version is used in all legal aspects (e.g. on Wikipedia and in
privacy/legal statements on
