From: Prasad Kumpatla <quic_pkumpatl@quicinc.com>

This patch adds basic SoundWire codec driver to support for
WCD9370/WCD9375 TX and RX devices.

The WCD9370/WCD9375 has Multi Button Headset Control hardware to
support Headset insertion, type detection, 8 headset buttons detection,
Over Current detection and Impedence measurements.
This patch adds support for this using wcd-mbhc apis.

Does this mean that the codec has 2 SoundWire interfaces?

If yes, aren't there merits in splitting the implementation in two
separate drivers, one for each interface and probing on the relevant partID?

This is how the RT713 was handled. The mic function was exposed as the
RT1713.

By representing the device as a single entity, things could be fun
because the two interfaces are really independent. things like clock
stop are handled at the interface level.

The code in this driver is difficult to review, for example in the probe
you wait for the TX part to complete the enumeration/initialization, but
there's nothing mentioned or stated on the RX part, and there's really
nothing related to the detection of this device. I don't actually see a
sdw_driver at all, it's a platform driver.

Would you mind adding a paragraph on how the SoundWire interfaces are
handled and how the SoundWire bus is involved if there's no sdw_driver?

Thanks!

Yes, Similar to WCD938x 
(https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/tree/sound/soc/codecs/wcd938x.c?h=next-20240507), 
it has two soundwire interfaces.

All read/write operations associated with WCD937x goes over tx_sdw.

rx_sdw_dev is unused in this driver. I will remove it.

wcd937x waits for TX part to complete as it is needed for register 
read/write operations.

Please refer patch 3/7 for slave driver.

Sure, will add details in the commit message.

Soundwire master driver is already upstreamed and is available at
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/tree/drivers/soundwire/qcom.c?h=next-20240507

Thanks & Regards,
