Subject: [PATCH 0/3] ASoC: Mediatek: Add support for MT8173 SoC
Date: Wed, 10 Jun 2015 22:24:33 +0800 [thread overview]
Message-ID: <1433946276-25969-1-git-send-email-koro.chen@mediatek.com> (raw)
This adds basic support for the Mediatek AFE (Audio Front End) unit for MT8173.
This patch is based on Linux 4.1-rc1 and Sascha's SCPSYS power patch [1].
The AFE unit comprises several memory interfaces that communicate with CPU,
a multi input multi output digital audio interconnect,
and several external interfaces (e.g. I2S).
[1] https://lkml.org/lkml/2015/6/9/172
changes since RFC:
- Use DPCM to model AFE
AFE memory interfaces such as DL1, VUL are modeled as frontend DAIs,
and AFE IOs such as I2S, HDMI are backend DAIs.
Which memif and IO to be used can be set in the machine driver.
There is no need to indicate this in dts anymore so
include/dt-bindings/sound/mtk-afe.h is removed.
AFE connections are represented by DAPM widgets and routes, and
set connection APIs/tables are no longer required.
(mtk-afe-connection.c and mtk-afe-connection.h are removed)
Instead, mixer controls are used to do connection/disconnection.
