Changes since v3:
- Rebase on linux-next

Changes since v2:
- Depend on :
  [1] https://patchwork.kernel.org/project/linux-mediatek/list/?series=681097
- Split dts settings into two patches based on belonging to MMSYS or MUTEX.

Changes since v1:
- Depend on :
  [1] https://patchwork.kernel.org/project/linux-mediatek/list/?series=681097
- Add compatible names to VPPSYS0 and VPPSYS1 in MMSYS binding file.
- Fix VPPSYS's MMSYS and MUTEX dts to pass the dtsb_check.
- Rename mtk_mmsys_merge_config() and mtk_mmsys_rsz_dcm_config() to
  mtk_mmsys_vpp_rsz_merge_config() and mtk_mmsys_vpp_rsz_dcm_config().
- Clean up mtk_mmsys_vpp_rsz_dcm_config().
- Add a comment to mtk_mutex_write_mod() and clean it up for use in more
  than 32 mods.

Hi,

This series add support for MT8195's two VPPSYS(Video Processor Pipe Subsystem),
under which there will be corresponding MMSYS and MUTEX settings that
need to be configured.

Hi Matthias,

May I send a new series without a fallback compatible like the mt8188
VDOSYS does?

Hi Matthias,

Sorry for the inaccurate information, the warning mentioned in [1/8] is
because vppsys 0/1 has already been defined in "mediatek,mt8195-
clock.yaml" as follows:

https://patchwork.kernel.org/project/linux-mediatek/patch/20210914021633.26377-2-chun-jie.chen@mediatek.com/

Is it possible to fix it by just removing [1/8], or should I send a new
series?

Regards,
Moudy

You will need to remove it from the clock binding and of course from the clock 
drivers. One example is this one:
https://patchwork.kernel.org/project/linux-mediatek/patch/20210914021633.26377-21-chun-jie.chen@mediatek.com/

In the end the mmsys will probe by the compatible and will then probe the clock 
driver as a platform driver.

Best regards,
Matthias
