Subject: [PATCH v5 00/16] Add VOP2 support on rk3588

From: Andy Yan <andy.yan@...k-chips.com>

This patch sets aims at enable the VOP2 support on rk3588.

Main feature of VOP2 on rk3588:
Four video ports:
VP0 Max 4096x2160
VP1 Max 4096x2160
VP2 Max 4096x2160
VP3 Max 2048x1080

4 4K Cluster windows with AFBC/line RGB and AFBC-only YUV support
4 4K Esmart windows with line RGB/YUV support

The current version support all the 8 windows with all the suppported
plane format.

And we don't have a upstreamed encoder/connector(HDMI/DP) for rk3588
yet, Cristian from collabora is working on adding upstream support for
HDMI on rk3588.

My current test(1080P/4KP60) is runing with a HDMI driver pick from
downstream bsp kernel.

A branch based on linux-6.7 rc4 containing all the series and
HDMI driver(not compatible with mainline rk3568 hdmi) picked
from downstream bsp kernel is available [0].

- move blank line below  the status=disabled in vop dt node
- split iommu dt binding patch from this series

Changes in v4:
- drop redundant description.
- use full stop at all the description's end.
- address Krzysztof's review in v3
- keep all VOP2_FEATURE_HAS_xxx macros increase in order.
- check NULL pointer at right place
- fix the index of fb->obj
- drop explicitly cast of void pointer
- make the register dump code as a common function.

Changes in v3:
- split from the vop2 driver patch
- put bool variable yuv_overlay next to other bool variable
- define macro for RK3568_OVL_CTRL__YUV_MODE
- just write RK3568_OVL_CTRL register once in function
  vop2_setup_layer_mixer
- constrain properties in allOf:if:then
- some description updates
- change the subject as Krzysztof suggested, and add his ACK
- add braces for x in macro vop2_output_if_is_yyy(x)
- clear the bits of a mask before setting it in rk3588_set_intf_mux
- add more comments.
- put regs dump info in vop2_data

Changes in v2:
- fix errors when running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
- split form vop driver patch
- add rk3588_ prefix for functions which are rk3588 only
- make some calculation as fixed value and keep calculation formula as
  comment
- check return value for some cru calculation functions.
- check return value for syscon_regmap_lookup_by_phandle
- add NV20/NV30 for esmart plane
