I think I'm missing context here, I've basically been zoning out all the soundwire stuff - the patch series are huge and generate a bunch of discusion. Is the patch below the full thing?

Is the patch below the full thing? I don't see any obvious > problems. Here's a bit of context: This patch is really independent from the 40-odd fixes I pushed about 10 days ago. I provided an initial version back in April ('[PATCH v2 2/2] regmap: soundwire: fix Kconfig select/depend issue') during the first batch of updates. At the time, the suggested solution for the compilation issues was not agreed on, so the build errors remained - not a big deal they only show-up with codec drivers that were not upstreamed so far. It took me a while to come back to it but that was the first in my TODO list after my Summer break and now that we are almost ready to upstream those codec drivers it's a good time to revisit this issue. Your initial feedback was: "This now makes _SOUNDWIRE different to all the other bus types; if this is a good change then surely the same thing should be done for all the other bus types. " and "Alignment is a requirement. If you want to optimize this then it'd be better to optimize all the bus types rather than just having the one weird bus type that does something different for no documented reason." I don't have the knowledge or means to test what I suggested initially for the other buses, and the optimization was minimal anyways, so this patch takes the path of least resistance and aligns with others. if there are no objections it's probably easier to push this patch through the SoundWire tree, with the relevant Acks.
