* make compatible to c03d0b52ff71d5 ("drm/connector: Fix typo in output format")
* move "dw-hdmi/ingenic-dw-hdmi: repair interworking with hdmi-connector" before
  drm/ingenic: Add dw-hdmi driver specialization for jz4780 (by paul@crapouillou.net)
* split introduction of dw_hdmi_enable_poll() into separate patch
* explicitly mark plane f0 as not working in jz4780 (suggested by paul@crapouillou.net)
* drop 1/9 since it is now in drm-misc/drm-misc-next

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)

* 3/9: remove old hdmi-5v-power in the example (by paul@crapouillou.net)
* 2/9: disable handling of plane f0 only for jz4780 (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.

Fixes and changes:

- repair interworking of dw-hdmi with connector-hdmi (by hns@goldelico.com)
- fix JZ_REG_LCD_OSDC setup for jz4780 (by hns@goldelico.com and paul@crapouillou.net)
- 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 hns@goldelico.com)
- regulator code removed because we now use the "ddc-en-gpios" of the connector
  driver (suggested by paul@crapouillou.net)
- bindings: addition of "ddc-i2c-bus" and "hdmi-5v-supply" removed (suggested by robh+dt@kernel.org)
- 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 broonie@kernel.org)

PATCH V9 2021-11-24 22:29:14:
- 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)
             simplify/fix error handling and driver cleanup on remove (proposed 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)

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)
- fixed reg property in jz4780.dtsi to cover all registers incl. gamma and vee (by hns@goldelico.com)
- added a base patch to calculate regmap size from DTS reg property (requested by paul@crapouillou.net)

- 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)
