Subject: [PATCH v5 0/7] MIPS: JZ4780 and CI20 HDMI

PATCH V5  2021-10-05 14:28:44:
- dropped mode_fixup and timings support in dw-hdmi as it is no longer needed in this V5 (by
- dropped "drm/ingenic: add some jz4780 specific features" (stimulated by
- fixed typo in commit subject: "synopsis" -> "synopsys" (by
- swapped clocks in jz4780.dtsi to match synopsys,dw-hdmi.yaml (by
- improved, simplified, fixed, dtbschecked ingenic-jz4780-hdmi.yaml and made dependent of bridge/synopsys,dw-hdmi.yaml (based on suggestions by
- fixed binding vs. driver&DTS use of hdmi-5v regulator (suggested by
- dropped "drm/bridge: synopsis: Fix to properly handle HPD" - was a no longer needed workaround for a previous version
  (suggested by

PATCH V4 2021-09-27 18:44:38:
- fix setting output_port = 1 (issue found by
- ci20.dts: convert to use hdmi-connector (by
- add a hdmi-regulator to control +5V power (by
- added a fix to dw-hdmi to call drm_kms_helper_hotplug_event on plugin event detection (by
- always allocate extended descriptor but initialize only for jz4780 (by
- updated to work on top of "[PATCH v3 0/6] drm/ingenic: Various improvements v3" (by
- rebased to v5.13-rc3

PATCH V3 2021-08-08 07:10:50:
This series adds HDMI support for JZ4780 and CI20 board (and fixes one IPU related issue in registration error path)
- [patch 1/8] switched from mode_fixup to atomic_check (suggested by
  - the call to the dw-hdmi specialization is still called mode_fixup
- [patch 3/8] diverse fixes for ingenic-drm-drv (suggested by
  - factor out some non-HDMI features of the jz4780 into a separate patch
  - multiple fixes around max height
  - do not change regmap config but a copy on stack
  - define some constants
  - factor out fixing of drm_init error path for IPU into separate patch
  - use FIELD_PREP()
- [patch 8/8] conversion to component framework dropped (suggested by and

PATCH V2 2021-08-05 16:08:05:
This series adds HDMI support for JZ4780 and CI20 board

- code and commit messages revisited for checkpatch warnings
- rebased on v5.14-rc4
- include (failed, hence RFC 8/8) attempt to convert to component framework
