Hello,

This series cleans up, reworks and extends the rkisp1 driver to support
the ISP found in the NXP i.MX8MP SoC.

The ISP IP cores in the Rockchip RK3399 (known as the "Rockchip ISP1")
and in the NXP i.MX8MP have the same origin, and have slightly diverged
over time as they are now independently developed (as far as I
understand) by Rockchip and VeriSilicon. The latter is marketed under
the name "ISP8000Nano", and is close enough to the RK3399 ISP that it
can easily be supported by the same driver.

This series starts with a few changes to the V4L2 async framework
(01/55) and MC core helpers (02/55 to 04/55) to support the rest of the
changes. It continues with various cleanups and reworks in order to
support CSI-2 receivers external to the ISP as found in the i.MX8MP
(05/55 to 45/55). Patch 46/55 is a small debugging improvement, and
patches 47/55 to 55/55 then add i.MX8MP support.

Compared to v1, patches have been shuffled around a bit so that patches
01/55 to 45/55 should be ready in time for integration in v5.20, while
the remaining patches may take one more kernel release. See individual
patches for detailed changelogs.

Review comments from v1 have been taken into account, except for patches
46/55, 48/55, 50/55 and 55/55 as discussion are still ongoing there.

This series depends on v4 of "media: rkisp1: Misc bug fixes and
cleanups" ([1]), which has been accepted in the Linux media tree for
v5.20.
