PATCH V13 2022-02-02 17:31:22:
* 7/9: remove call to gpiod_set_value() because of GPIOD_OUT_HIGH (by paul@crapouillou.net)

PATCH V12 2022-01-31 13:26:54:
This version reworks how hdmi ddc power is controlled by connector and not
by ddc/hdmi bridge driver.

Also some patches of the previous version of this series have been removed
since they are already applied to mips-next/linux/next/v5.17-rc1.

  driver (suggested by paul@crapouillou.net)

- patch 6/8: remove optional <0> for assigned-clocks and unintentionally included "unwedge" setup (found by paul@crapouillou.net)
- patch 4/8: some cosmetics
             make regulator enable/disable only if not NULL (found by paul@crapouillou.net)

- patch 3/8: fix #include path in example (found by paul@crapouillou.net)
             fix missing "i" in unevaluatedProperties (found by robh@kernel.org)

- adjusted assigned-clocks changes to upstream which added some for SSI (by hns@goldelico.com)
- rebased and tested with v5.16-rc2 + patch set drm/ingenic by paul@crapouillou.net (by hns@goldelico.com)

PATCH V6 2021-11-10 20:43:33:
- changed CONFIG_DRM_INGENIC_DW_HDMI to "m" (by hns@goldelico.com)
- made ingenic-dw-hdmi an independent platform driver which can be compiled as module
  and removed error patch fixes for IPU (suggested by paul@crapouillou.net)
- moved assigned-clocks from jz4780.dtsi to ci20.dts (suggested by paul@crapouillou.net)

- improved, simplified, fixed, dtbschecked ingenic-jz4780-hdmi.yaml and made dependent of bridge/synopsys,dw-hdmi.yaml (based on suggestions by maxime@cerno.tech)
- fixed binding vs. driver&DTS use of hdmi-5v regulator (suggested by maxime@cerno.tech)
- dropped "drm/bridge: synopsis: Fix to properly handle HPD" - was a no longer needed workaround for a previous version
  (suggested by maxime@cerno.tech)

PATCH V4 2021-09-27 18:44:38:

Hi Nikolaus,

I tried applying patches 1-2, but they don't apply cleanly on top of 
drm-misc/drm-misc-next.

Could you rebase on top of that tree?

Cheers,

Ok I had rebased to linux-next some days ago and it appears that patch 1/9 has now arrived in drm-misc/drm-misc-next.
So we can drop 1/9.

Sure.

Unfortunatley my v14 breaks the display again. It is not much fun to develop on top of such a moving target...
So I have to find out first what was broken this time before I can send out a new version.

Yes, some weeks ago I did apply patch 1/9 from one of your previous 
patchsets. Patch 2 was applied as well (commit b807fd2c43fe 
("drm/ingenic: Add support for JZ4780 and HDMI output")), but you then 
said that it didn't work and needed a fix.

For this patchset you should always base on top of 
drm-misc/drm-misc-next, and not on linux-next; they have different 
schedules. You can drop patch #1, and rework patch #2 so that it only 
fixes the previously incorrect behaviour.

Have found it. Was a typo in a rebase conflict resolution...

So, v14 can come now.
