Hello,
This patch series attempts to separate image format handling between devices in the i.MX5/6 and i.MX7/8 families.
The first patch in the series implements the suggestion I received from Philipp Zabel as feedback to the previous series.
The last 3 could in principle be submitted as a single patch, but I opted for minimal changes, for reviewing clarity.
The last patch is the core of the change, where i.MX5/6 uses the old code path, and i.MX7/8 uses a slightly redacted copy of it. I have fairly limited experience with the parameters that go into determining the format, so I opted only to adjust the part I have tested: the rounding.
Regards,
Dorota

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'd call the enum imx_media_device_type, but that's just a slight
preference:
