Subject: [PATCH v4 0/5] add audio support for Display Port on MSM
Date: Mon, 31 Aug 2020 11:22:53 -0700	[thread overview]
Message-ID: <20200831182258.16632-1-abhinavk@codeaurora.org> (raw)

This series adds audio support for DP on MSM chipsets. It leverages
the hdmi-codec interface [1] to communicate between the Display Port
driver and the audio subsystem. These changes depend on the series [2]
which adds Display Port support to MSM chipsets.

[1] https://patchwork.kernel.org/patch/11047883/
[2] https://patchwork.kernel.org/patch/11708677/

changes in v2:
    - fix up a compilation issue on drm-next branch

changes in v3:
    - add support to synchronize DP driver and audio during shutdown

changes in v4:
    - rebase on top of latest patchset of dependency

Abhinav Kumar (5):
  drm/msm/dp: store dp_display in the driver data
  drm/msm/dp: add audio support for Display Port on MSM
  drm/msm/dp: add hook_plugged_cb hdmi-codec op for MSM DP driver
  drm/msm/dp: signal the hotplug disconnect in the event handler
  drm/msm/dp: wait for audio notification before disabling clocks
