Subject: [PATCH v2 2/2] ASoC: add support for Conexant CX2072X CODEC
Date: Wed, 5 Apr 2017 17:07:14 +0800 [thread overview]
Message-ID: <5b7e78fef2c8e299d39ebaa560d81d66e619e7eb.1491382907.git.simon.ho@conexant.com> (raw)
In-Reply-To: <cover.1491382907.git.simon.ho@conexant.com>
In-Reply-To: <cover.1491382907.git.simon.ho@conexant.com>
From: Simon Ho <simon.ho@conexant.com>
Initial commit of the Conexant CX2072X CODEC driver. Some features are
not present.
The CX2072X is a ultra low power stereo audio codec supports I2S/TDM
host interface with EQ, DRC features in playback mode.
Featues of CX2072X codec:
* Two 24 bits DACs and DACs.
* Stereo Headphone AMP.
* 2.8W per channel class-D output.
* Integrated seven bands per channel EQ and DRC.
* Fully integrated headset support with detect/switch.
* Stereo digital microphone for array applications.
* S/PDIF output.
* Bi-directional GPIOs.
* Support analog and digital PC Beeep.
* One headset button support.
* Supports a wide variety of host interfaces.
-wide variety of I2S and similar bit-stream formats
with word lengths of up to 24 bits.
-TDM stream supports up to 4 channels.
* AEC loopback support.
