When calling debugfs functions, there is no need to ever check the
return value. The function can work or not, but the code logic should

The function imx_media_init_mbus_fmt() initializes the imx subdevice
mbus colorimetry to some sane defaults when the subdevice is registered.
Currently it guesses at a colorspace based on the passed mbus pixel
format. If the format is RGB, it chooses colorspace V4L2_COLORSPACE_SRGB,
and if the format is YUV, it chooses V4L2_COLORSPACE_SMPTE170M.
While that might be a good guess, it's not necessarily true that a RGB
pixel format encoding uses a SRGB colorspace, or that a YUV encoding
uses a SMPTE170M colorspace. Instead of making this dubious guess,
just default the colorspace to SRGB.

The imx_media_pixfmt structures include a codes member that stores
media bus codes as a fixed array of 4 integers. The functions dealing
with the imx_media_pixfmt structures assume that the array of codes is
terminated by a 0 element. This mechanism is fragile, as demonstrated
by several instances of the structure containing 4 non-zero codes.
Fix this by turning the array into a pointer, and providing an
IMX_BUS_FMTS macro to initialize the codes member with a guaranteed 0
element at the end.

where the boolean parameters can easily be mixed. To make the code

parameter.

selection as CS_SEL_YUV_RGB, and that is used by sub-devices that
don't support BAYER and only allow selecting and enumerating YUV or RGB

The imx7-mipi-csis only uses the imx_media_init_mbus_fmt() function from
the imx-media-utils helpers. The helpers don't support all the media bus
formats used by this driver, and are thus a bad fit. As the MIPI CSIS is
a standalone IP core that could be integrated in other SoCs, let's not
use the helper.

The driver rejects enablement of multiple links on its source pad. This
isn't needed, as the CSIS doesn't care. Drop it.
