[PATCH 00/17] Add a new SoundWire enumeration helper

[PATCH 00/17] Add a new SoundWire enumeration helper

[Charles Keepax]

Add a new SoundWire enumeration helper function, many drivers have
almost identical code in runtime resume so it makes sense to move this
to the core.

It is worth noting this is really step one of a larger process, there
are a few drivers that do more custom things and are not covered by this
series. But this series picks up the low hanging fruit and moves things
in a good direction.

The next step is to look at drivers that also wait at probe time, where
the unattached_request flag is not going to be valid.

Thanks,
Charles

[PATCH 01/17] soundwire: Add a helper function to wait for device initialisation

[Charles Keepax]

Add a new helper function to wait for the device to enumerate
and be initialised by the SoundWire core. Most of the SoundWire
drivers have very similar boiler plate code in their runtime
resume, and that boiler plate tends to access various internals
of the SoundWire structs which is a mild layering violation.

Adding a new core helper function greatly eases both of these
issues.

Sorry Vinod, it appears I somehow completely forgot to CC you on
this series. Let me know if you got it through the mailing list,
and if not I will do a resend.

This should also probably get a stub for the no soundwire case.

We now always fall through to this block of code instead of exiting
early if the device wasn't actually reset, the new helper doesn't
distinguish between no reset and successfully waited for reset.

Thanks will give a couple days for any other comments then do a
