[PATCH 00/13] ASoC: Move IO and kcontrols to the component level

[Lars-Peter Clausen <lars@metafoo.de>]

Hi,

This series is the first step towards full componentisation of the ASoC core. It
moves both the IO abstraction layers within ASoC as well as the standard set of
kcontrols to the component level. This for example means we can get rid of
constructs like

	if (w->codec)
		snd_soc_read(....)
	else if(w->platform)
		snd_soc_platform_read(...)

Moving the kcontrols to the component level means we can use the same
implementation also for other non-CODEC components. E.g. there seems to be an
increasing amount of CPU components that have basic signal processing and things
like volume controls etc. whose register layout is similar to those used in
CODECs. Currently each CPU component driver re-implements these controls by
hand.

The first two patches introduce two new helper functions which hide the actual
implementation on how the CODEC or platform struct that register a control can
be obtained from the control. This means that when the actual implementation is
changed only the two helper functions need to be updated and not every single
driver. The patches that follow that are just cleanups removing unused IO stuff
and move all IO functions to soc-io.c. The next step is to make platforms also
components. And then finally first the IO abstraction layers in ASoC are unified
at the component level and then on top of that the kcontrol helpers are moved to
the component level.

The series depends on quite a few topic branches related to changes to the core
and cleanups for individual drivers. It is probably best to place it on top of
asoc-v3.15-2. The patch that moves the kcontrols to the component level also has
a runtime dependency on the not yet applied patches that move the ams-delta and
mfld_machine controls to the card level.
