Subject: [PATCH v6 0/5] Add audio support for MSM DisplayPort driver
Date: Sat, 12 Sep 2020 13:49:27 -0700 [thread overview]
Message-ID: <20200912204932.21232-1-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]
and [3] which add Display Port support to MSM chipsets.
