I'm testing this series on the Nexus 5, and I'm able to communicate with the HDMI bridge via the analogix-anx78xx driver, however the external display is not working yet. When I plug in the HDMI cable, the monitor detects that a device is hooked up, but nothing is shown on the external monitor. The hot plug detect GPIO (hpd-gpios) on the analogix-anx78xx bridge and MSM HDMI drivers do not change state when the slimport adapter or HDMI cable is plugged in or removed. I wonder if a regulator is not enabled somewhere? I have a comment in patch 10 regarding 'hpd-gdsc-supply' that may potentially be an issue. I'm still digging in on this, however I'd appreciate any feedback if anyone has time. Most of these patches are ready now, so I marked the ones that aren't ready with 'PATCH RFC'. I'm using an Analogix Semiconductor SP6001 SlimPort Micro-USB to 4K HDMI Adapter to connect my phone to an external display via a standard HDMI cable. This works just fine with the downstream MSM kernel using Android.
