This series adds support to the CFE hardware block on RaspberryPi 5. The
CFE (Camera Front End) contains a CSI-2 receiver and Front End, a small
ISP.

This series is currently based on multiple other serieses:

- Sakari's "[PATCH v8 00/38] Generic line based metadata support, internal
pads" for metadata support
- Laurent's "[PATCH 00/15] media: Add driver for the Raspberry Pi <5
CSI-2 receiver" for a few new pixel formats and imx219 (for testing).
- Jacopo's "[PATCH v5 0/9] media: raspberrypi: Add support for PiSP Back
End" for some shared uapi headers.

And to run this, one of course needs the basic RPi5 kernel support plus
relevant dts changes to enable the cfe and camera.

Which makes it impossible to merge. Please work on decoupling.

Yes, it's not for merging as I wrote: "So at the moment we cannot merge this driver, but hopefully the dependencies will get merged before the reviews on this one are done."

I believe Sakari's and Jacopo's serieses should be very close to merging, and those should satisfy the needs of the driver itself.

The DT bindings example uses a header from RPi5 base support series, and if merging the base support seems to take a long time, I guess I could drop the include and just use numbers instead for RP1_INT_MIPI0 and RP1_CLK_MIPI0_CFG. And change those back later when the base support is merged.
