[PATCH v4 0/5] Add Mediatek ISP3.0

[Julien Stephan]

This series adds the support of the Mediatek ISP3.0 found on some
Mediatek SoCs such as the mt8365. The driver is divided into 2 parts:

* SENINF: the sensor interface
* CAMSV: this driver provides a path to bypass the SoC ISP so that image
  data coming from the SENINF can go directly into memory without any
  image processing. This allows the use of an external ISP or camera
  sensor directly.

The SENINF driver is based on previous work done by Louis Kuo available
as an RFC here: https://lore.kernel.org/all/20200708104023.3225-1-louis.kuo@xxxxxxxxxxxx/

This series depends on the following series for the phy [1]

Changes in v4:
- fix suspend/resume deadlock
- fix various locking issues reported by Laurent Pinchart on v3
- run LOCKDEP
- add missing include reported by kernel-test-robot for non mediatek arch and COMPILE_TEST=y
- use atomic poll inside mtk_camsv30_setup
- drop second lane support as it was not used 
- remove useless members in structs
- fix media entity initialization
- initialize correct pad for camsv video device
- add isp support in mt8365.dtsi
- rebase on 6.7

Changes in v3:
- fix a lot of formatting issues/coding style issues found in camsv/seninf reported by Angelo on v2
- fix camsv/seninf binding file error reported by Rob

Changes in v2:
- renamed clock `cam_seninf` to `camsys`
- renamed clock `top_mux_seninf` to `top_mux`
- moved phy properties from port nodes to top level
- remove patternProperties
- specify power management dependency in the cover letter description to fix
  missing include in dt-binding example
- change '$ref' properties on some endpoint nodes from
  '$ref: video-interfaces.yaml#' to '$ref: /schemas/graph.yaml#/$defs/endpoint-base'
 where applicable
