Subject: [PATCH 00/11] ARM: dts: qcom: msm8974: add support for external display
Date: Wed, 14 Aug 2019 20:48:43 -0400	[thread overview]
Message-ID: <20190815004854.19860-1-masneyb@onstation.org> (raw)

This patch series begins to add support for the external display over
HDMI that is supported on msm8974 SoCs. 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.
