This is the v2 the mux driver part of v1. This series is developed for
and tested on MT8173 board, whose layout looks like:
/-- anx7688
-- MT8173 HDMI bridge -- GPIO mux
\-- native HDMI
v1: https://patchwork.kernel.org/project/dri-devel/cover/20191211061911.238393-1-hsinyi@xxxxxxxxxxxx/
The other drm bridge callbacks is dropped in this version because:
- The non-atomic callbacks are deprecated
- It would be complicated to pass the atomic state to the downstream
- We actually don't have the hardware to test them
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
- Updated the license: "GPL v2" --> "GPL"
