[ Upstream commit 7417b1b1f36cc214dc458e717278a27a912d3b51 ]

Always assign *val to 0 in cci_read(). This has the benefit of not
requiring initialisation of the variables data is read to using
cci_read(). Once smatch is fixed, it could catch the use of uninitialised
reads.

Some sensors, e.g. Sony IMX290, are using little-endian registers. Add
support for those by encoding the endianness into Bit 20 of the register
address.

[ Upstream commit cd93cc245dfe334c38da98c14b34f9597e1b4ea6 ]

Add CCI_REG_WIDTH() macro to obtain register width in bits and similarly,
CCI_REG_WIDTH_BYTES() to obtain it in bytes.

Also add CCI_REG_ADDR() macro to obtain the address of a register.

Use both macros in v4l2-cci.c, too.

Pull media updates from Mauro Carvalho Chehab:

- new i2c drivers: ds90ub913, ds90ub953, ds90ub960, dw9719, ds90ub913

- new Intel IVSC MEI drivers

- some Mediatek platform drivers were moved to a common location

- Intel atomisp2 driver is now working with the main ov2680 driver. Due
to that, the atomisp2 ov2680 staging one was removed

- the bttv driver was finally converted to videobuf2 framework. This
was the last one upstream using videobuf version 1 core. We'll likely
remove the old videobuf framework on 6.7

- lots of improvements at atomisp driver: it now works with normal I2C
sensors. Several compile-mode dependecies to select between ISP2400
and ISP2401 are now solved in runtime

- a new ipu-bridge logic was added to work with IVSC MEI drivers

- venus driver gained better support for new VPU versions

- the v4l core async framework has gained lots of improvements and
cleanups

- lots of other cleanups, improvements and driver fixes

media: Add MIPI CCI register access helper functions

The CSI2 specification specifies a standard method to access camera sensor
registers called "Camera Control Interface (CCI)".

This uses either 8 or 16 bit (big-endian wire order) register addresses
and supports 8, 16, 24 or 32 bit (big-endian wire order) register widths.

Currently a lot of Linux camera sensor drivers all have their own custom
helpers for this, often copy and pasted from other drivers.

Add a set of generic helpers for this so that all sensor drivers can
switch to a single common implementation.

These helpers take an extra optional "int *err" function parameter,
this can be used to chain a bunch of register accesses together with
only a single error check at the end, rather than needing to error
check each individual register access. The first failing call will
set the contents of err to a non 0 value and all other calls will
then become no-ops.
