[PATCH v4 00/13] Miscellaneous Mali-C55 Pipeline Fixes

[Daniel Scally]

v3-v4: based on the v6 of the kernel driver [1]
- Collecting tags
- Added patches correcting the representation of input/output formats (#10)
- Added a patch enabling links between resizer and capture device, which in the
  latest version of the kernel driver are mutable (#11)
- Added the ScalerCrop patches back in (#12 and #13)

v2->v3:
- Collect additional tags
- Add 3 patches to add Mali C55 media bus formats to libcamera and to fix
  20-bit format propagation to CSI-2 to ISP

v1->v2
- Drop ScalerCrop and scaler handling
- Limit ISP input size to 640x480
- Adjust the RAW configuration stride and image size to 4 bytes

Hi all

This set contains a number of fixes to the Mali-C55 pipeline handler that have
been in our development tree whilst we worked on the IPA module - they weren't
posted before because things have been in quite a lot of flux, but now that the
IPA patchset is itself public it's time for these to go upstream too.

Thanks
Dan
