Do any of these Kconfig changes actually fix any real issue?  It looks
like they are all just "cleanups" to me.  What problem are they solving?

Hi Mark,




Vinod, Mark, any feedback?



There will be a set of SoundWire codec drivers provided upstream soonish and
we'll get a number of kbuild errors without this patch.


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?  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.

[PATCH] soundwire: fix regmap dependencies and align with other serial links

2019-07-18 Thread Pierre-Louis Bossart
The existing code has a mixed select/depend usage which makes no sense.

config SOUNDWIRE_BUS
   tristate
   select REGMAP_SOUNDWIRE

config REGMAP_SOUNDWIRE
tristate
depends on SOUNDWIRE_BUS

Let's remove one layer of Kconfig definitions and align with the
solutions used by all other serial links.
