Subject: [PATCH 0/9] ASoC: QCOM: Add support for ipq806x SOC
Date: Wed, 19 Nov 2014 10:52:40 -0800 [thread overview]
Message-ID: <1416423169-21865-1-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 machine driver that handles the board-specific pins
- a native driver that handles hardware access to the LPAIF
- a CPU DAI driver for controlling the LPAIF block
- a PCM MI2S platform driver
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.
