Very few variations from the recent v3, just reflowed some text and dropped
a plural name in 6/7 commit message.

The imx7-mipi-csis driver is in a good state and can be destaged.
Move the imx7-mipi-csis.c driver to the newly created
drivers/media/platform/imx directory and plumb the related
options in Kconfig and in Makefile.

Rename the imx7-mipi-csis.c driver to remove the reference to i.MX7.
The driver is for an IP core found on i.MX7 and i.MX8 SoC, so do not
specify a SoC version number in the driver name.
Remove the references to the i.MX7 SoC in the driver symbols and expand
the driver's header with more information about the IP core the driver
controls.
Also rename the associated bindings documentation.

Rename the imx7-mipi-csis.c driver to remove the reference to i.MX7.
The driver is for an IP core found on i.MX7 and i.MX8 SoC, so do not
specify a SoC version number in the driver name.
Remove the references to the i.MX7 SoC in the driver symbols and expand
the driver's header with more information about the IP core the driver
controls.
Also rename the associated bindings documentation.

The CSI bridge should operate in dual components mode when it is
connected to a pixel transmitter that transfers two components at a time
in YUV 422 formats (16 bits, Y + U/V).
Use the image format variants to determine if single or dual component mode
should be used.
Add a note to the TODO file to record that the list of supported formats
should be restricted to the SoC model the CSI bridge is integrated on
to avoid potential pipeline mis-configurations.

Bits 13 and 12 of the ISP_CONFIGn register configure the PIXEL_MODE
which specifies the sampling size, in pixel component units, on the
CSI-2 output data interface when data are transferred to memory.
The register description in the chip manual specifies that DUAL mode
should be used for YUV422 data.

Add support for the BGR888_1X24 image format.
No existing media bus codes describe exactly the way data is transferred
on the CSI-2 bus. This is not a new issue, the CSI-2 YUV422 8-bit format
is described by MEDIA_BUS_FMT_UYVY8_1X16 which is an arbitrary
convention and not an exact match. Use the MEDIA_BUS_FMT_BGR888_1X24 to
follow the same convention, based on the order in which bits are
transmitted over the CSI-2 bus.

Due to how pixel components are transmitted on the CSI-2 serial bus
and how they are deserialized by the CSI-2 receiver, the component
ordering might change and the image formats on the sink and source pads
of the receiver should reflect it.
For RGB24, in example, the component ordering on the wire as described by
the CSI-2 specification matches the BGR888 format, while once
deserialized by the CSIS receiver it matches the RGB888 format.
Add an additional .output field to struct csis_pix_format to allow
propagating the correct format to the source pad after a format
configuration on the sink.
The change is only relevant for RGB24 but paves the way for further
format translations in future.
