Hi,
Compared to v3, this patch series introduces the checks of imx_media_find_mbus_format return values in patch 4 and 5.
Cheers,
Dorota

imx_media_find_mbus_format has NULL as a valid return value,
therefore the caller should take it into account.

I should mention that this part from v3 still applies:
> The use of `v4l2_fill_pixfmt` comes with the downside of breaking 10-bit Bayer formats, or at least until my other series gets accepted
The other series is:
Message-id: [email protected]
https://lore.kernel.org/linux-media/[email protected]/
Regards,

This splits out a format handler which takes into account
the capabilities of the i.MX7/8 video device,
as opposed to the default handler compatible with both i.MX5/6 and i.MX7/8.

The driver covers i.MX5/6, as well as i.MX7/8 hardware.
Those implementations differ, e.g. in the sizes of buffers they accept.
Some functionality should be abstracted, and storing type achieves that.

I'm not so sure about creating an enum for this. Perhaps just a 'bool is_imx56'
would be sufficient. The argument name is also more understandable. And you also
don't have the issue of having to check for out-of-range type values.
Also, where is the device type set for imx8mq? I'm not all that familiar with
the imx code, but I don't see where imx8mq-mipi-csi2.c fills that in.
I will merge patch 1/5, that one makes sense, but I'll skip the others.
Regards,
Hans
