Subject: [Patch V3 00/10] ASoC: QCOM: Add support for ipq806x SOC
Date: Wed, 24 Dec 2014 08:42:00 -0800 [thread overview]
Message-ID: <1419439330-2303-1-git-send-email-kwestfie@codeaurora.org> (raw)
From: Kenneth Westfield <kwestfie@codeaurora.org>
This set of patches adds support for audio on the Qualcomm Technologies
ipq806x SOC.
The ipq806x SOC has audio-related hardware blocks in its low-power audio
subsystem (or LPASS). One of the relevant blocks in the LPASS is its low-power
audio interface (or LPAIF). This encapsulates the MI2S port, which is what
these drivers are configured to use. The I2S pins are connected to an external
DAC/amp chip. In addition, a single GPIO is connected to the same DAC/amp,
which gives the SOC enable/disable control.
The specific drivers added are:
- a Codec DAI driver that controls the SOC external pins
- a CPU DAI driver for controlling the LPASS-LPAIF block
- a PCM MI2S platform driver
These drivers, together, are used by simple-audio-card to complete the audio
implementation. Corresponding additions to the device tree for the ipq806x and
its documentation has also been added. Also, as this is a new directory, the
MAINTAINERS file has been updated as well.
== Updates from my previous post:
[Patch v2 00/11] ASoC: QCOM: Add support for ipq806x SOC
http://thread.gmane.org/gmane.linux.ports.arm.msm/10989
- Removed the PCM platform driver from the DTS platform and tied it to the
CPU DAI driver.
- Changed I2S pinctrl to use generic naming convention and moved control to
CPU DAI driver. It should be controlled now by soc-core's pinctrl_pm_*
functionality.
- Added stub DAPM support in codec driver. As the DAC GPIO needs to be
enabled last when starting playback, and disabled first when stopping
playback, it seems as though the trigger function may be the place for this.
Suggestions are welcome for a better place to put this.
- Removed machine driver and tied DAI drivers to simple-audio-card.
- Packaged the build files and Maxim codec files together in one change.
- Removed QCOM as vendor from Maxim code and documentation.
- Separated the SOC and board definitions into the correct DTS files.
- Update device tree documentation to reflect changes.
- General code cleanup.

dependencies (lcc)
