Subject: [PATCH v11 0/6] media: atmel: atmel-isc: driver redesign
This series is a continuation of the series that converts the atmel-isc driver
to media controller paradigm:
https://lore.kernel.org/lkml/20220503095127.48710-1-eugen.hristev@microchip.com/T/#mccad96a3122f2817bf1ae1db7eddf1a8cecb2749
As discussed on ML, the current Atmel ISC driver is moved to staging to keep the
existing users happy, and readded to platform/microchip under a different
Kconfig symbol and with the new media controller support which was reviewed in
v10.
I kept the original v10 patches on top of the movement of the driver
to make it more clear what the conversion to media controller brings.
Please let me know if this is okay or acceptable to take as it is,
and if it complies with the requirements for the subsystem/ABI breakage, etc.
Thanks to everyone for reviewing and helping in the discussions !
PLEASE NOTE: the series depends on the patch:
vb2: add support for (un)prepare_streaming queue ops
by Hans Verkuil
I have a different patch as the last in the series that uses the new callbacks
(and only that patch is dependant on the
vb2: add support for (un)prepare_streaming queue ops
)

Changes in v11:
- moved atmel isc to staging
- created platform/microchip to host the new MICROCHIP_ISC driver
- it was natural to move the MICROCHIP_CSI2DC here
- on top, add the patches that move to media controller
Full series history:
Changes in v10:
-> split the series into this first fixes part.
-> moved IO_MC addition from first patch to the second patch on the driver changes
-> edited commit messages
-> DT nodes now disabled by default.
Changes in v9:
-> kernel robot reported isc_link_validate is not static, changed to static.
Changes in v8:
-> scaler: modified crop bounds to have the exact source size
Changes in v7:
-> scaler: modified crop bounds to have maximum isc size
-> format propagation: did small changes as per Jacopo review
Changes in v6:
-> worked a bit on scaler, added try crop and other changes as per Jacopo review
-> worked on isc-base enum_fmt , reworked as per Jacopo review
Changes in v5:
-> removed patch that removed the 'stop' variable as it was still required
-> added two new trivial patches
-> reworked some parts of the scaler and format propagation after discussions with Jacopo
Changes in v4:
-> as reviewed by Hans, added new patch to remove the 'stop' variable and reworked
one patch that was using it
-> as reviewed by Jacopo, reworked some parts of the media controller implementation
Changes in v3:
- change in bindings, small fixes in csi2dc driver and conversion to mc
for the isc-base.
- removed some MAINTAINERS patches and used patterns in MAINTAINERS
Changes in v2:
- integrated many changes suggested by Jacopo in the review of the v1 series.
- add a few new patches
