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.

Fixes and changes:

- repair interworking of dw-hdmi with connector-hdmi (by [e-mail])
- fix JZ_REG_LCD_OSDC setup for jz4780 (by [e-mail] and [e-mail])
- adjustments for ci20.dts to use connector gpio for +5v (suggested by several)
- to add control of "ddc-en-gpios" to hdmi-connector driver (by [e-mail])
- regulator code removed because we now use the "ddc-en-gpios" of the connector
  driver (suggested by [e-mail])
- bindings: addition of "ddc-i2c-bus" and "hdmi-5v-supply" removed (suggested by [e-mail])
- rebase on v5.17-rc2

PATCH V11 2021-12-02 19:39:52:
- patch 4/8: change devm_regulator_get_optional to devm_regulator_get and
             remove NULL check (requested by [e-mail])
- patch 3/8: make hdmi-5v-supply required (requested by [e-mail])

PATCH V10 2021-11-30 22:26:41:
- patch 3/8: fix $id and $ref paths (found by [e-mail])

PATCH V9 2021-11-24 22:29:14:
- patch 6/8: remove optional <0> for assigned-clocks and unintentionally included "unwedge" setup (found by [e-mail])
- patch 4/8: some cosmetics
             make regulator enable/disable only if not NULL (found by [e-mail])
             simplify/fix error handling and driver cleanup on remove (proposed by [e-mail])
- patch 3/8: fix #include path in example (found by [e-mail])
             fix missing "i" in unevaluatedProperties (found by [e-mail])
             fix 4 spaces indentation for required: property (found by [e-mail])

- fix a bad editing result from patch 2/8 (found by [e-mail])

PATCH V7 2021-11-23 18:46:23:
- changed gpio polarity of hdmi_power to 0 (suggested by [e-mail])
- fixed LCD1 irq number (bug found by [e-mail])
- removed "- 4" for calculating max_register (suggested by [e-mail])
- use unevaluatedPropertes instead of additionalProperties (suggested by [e-mail])

- fixed reg property in jz4780.dtsi to cover all registers incl. gamma and vee (by [e-mail])

- swapped clocks in jz4780.dtsi to match synopsys,dw-hdmi.yaml (by [e-mail])

- fixed binding vs. driver&DTS use of hdmi-5v regulator (suggested by [e-mail])
- dropped "drm/bridge: synopsis: Fix to properly handle HPD" - was a no longer needed workaround for a previous version
  (suggested by [e-mail])

- fix setting output_port = 1 (issue found by [e-mail])
- ci20.dts: convert to use hdmi-connector (by [e-mail])
- add a hdmi-regulator to control +5V power (by [e-mail])
- added a fix to dw-hdmi to call drm_kms_helper_hotplug_event on plugin event detection (by [e-mail])
- always allocate extended descriptor but initialize only for jz4780 (by [e-mail])
- updated to work on top of "[PATCH v3 0/6] drm/ingenic: Various improvements v3" (by [e-mail])
- rebased to v5.13-rc3

PATCH V3 2021-08-08 07:10:50:

- rebased on v5.14-rc4
