Subject: [PATCH v9 0/9] ASoC: codecs: add wcd938x support
Date: Wed,  9 Jun 2021 10:09:34 +0100	[thread overview]
Message-ID: <20210609090943.7896-1-srinivas.kandagatla@linaro.org> (raw)

This patchset adds support for Qualcomm WCD938X codec.

Qualcomm WCD9380/WCD9385 Codec is a standalone Hi-Fi audio codec IC
connected over SoundWire. This device has two SoundWire devices, RX and
TX respectively supporting 4 x ADCs, ClassH, Ear, Aux PA, 2xHPH,
7 x TX diff inputs, 8 DMICs and MBHC.

Eventhough this device has two SoundWire devices, only tx device has
access to main codec Control/Status Registers!

For codec driver to be functional it would need both tx and rx Soundwire devices
to be up and this is taken care by using device component framework and device-links
are used to ensure proper pm dependencies. Ex tx does not enter suspend
before rx or codec is suspended.

This patchset along with other SoundWire patches on the list
have been tested on SM8250 MTP device.

Thanks,
srini
