[PATCH v3 0/5] Add generic-display-mux driver and bindings

[Pin-yen Lin <treapking@chromium.org>]

This series is developed for and tested on MT8173 board, and the layout is:

                                  /-- anx7688
-- MT8173 HDMI bridge -- GPIO mux
                                  \-- native HDMI

v2: https://lore.kernel.org/all/20230116110820.2615650-1-treapking@chromium.org/
v1: https://patchwork.kernel.org/project/dri-devel/cover/20191211061911.238393-1-hsinyi@chromium.org/

Changes in v3:
- Removed ddc-i2c-bus in the gpio-mux bridge bindings
- Added .get_edid callback in generic-gpio-mux driver
- Removed .get_edid callback in mtk_hdmi.c
- Modified anx7688 driver and binding to add a .get_edid callback

Changes in v2:
- Referenced existing dt-binding schemas from graph.yaml
- Added ddc-i2c-bus into the bindings
- Dropped attach/mode_set/enable/disable callbacks
- Fixed style issues
- Removed the special case for the HDMI connector
- Made the driver only read the GPIO status in IRQ handler
- Rebased to drm-misc-next
- Update the license: "GPL v2" --> "GPL"
