[PATCH 00/17] MOP500 Audio fix-ups and DT enablement

[Lee Jones]

This patch-set provides the MOP500 Audio driver with a few small
fix-ups along with Device Tree enablement for MOP500 Core and the
MSPs. You'll notice that we've left the PCM out for the time being
and continue to register that using platform code. This is because
we're still in the middle of discussions pertaining to how this
pseudo-device should be handled. We also pass pinctrl responsibility
to the MSP driver instead of setting it up in platform code, which
is an unnecessary over-head.

[PATCH 01/17] ASoC: Ux500: Move MSP pinctrl setup into the MSP driver

[Lee Jones]

In the initial submission of the MSP driver msp1 and msp3's associated
pinctrl mechanism was passed back to platform code using a plat_init()
call-back routine, but it has no place in platform code. The MSP driver
should set this up for the appropriate ports. Instead we use a use_pinctrl
identifier which is passed from platform_data/Device Tree which indicates
which ports should use pinctrl.

[PATCH 02/17] ASoC: Ux500: Enable MOP500 driver for Device Tree

[Lee Jones]

Here we ensure that the MOP500 audio driver will be probed during a
Device Tree boot. We also parse the sound node to link together the
codec, dma and the CPU-side Digital Audio Interface.

Register both parts of the MSP driver from Device Tree so that they

[PATCH 04/17] ASoC: codecs: Enable AB8500 CODEC for Device Tree

[Lee Jones]

We continue to allow the AB8500 CODEC to be registered via the AB8500
Multi Functional Device API, only this time we extract its configuration
from the Device Tree binary.

[PATCH 10/17] ARM: ux500: Fork MSP platform registration for step-by-step DT enablement

[Lee Jones]

We've done this before and it worked well last time. Here we're
duplicating a complex registration function to ease the process
of enabling it for Device Tree. As there are quite a few steps
taken during the registration process, it makes sense to break
them up into more manageable chunks. This patch will aid us.

[PATCH 11/17] ARM: ux500: Pass MSP DMA platform data though AUXDATA

[Lee Jones]

It isn't currently possible to pass all platform specific configuration
though Device Tree. Thinks like device names used in the clock
infrastructure, call-backs and DMA information have to be passed in via
AUXDATA structures and the MSP is no exception. Here we're passing DMA
settings.

[PATCH 12/17] ARM: ux500: Stop registering the MOP500 Audio driver from platform code

[Lee Jones]

In this patch we prevent MOP500 driver registration from platform
code and rely solely on Device Tree to do the probing for us.

[PATCH 13/17] ARM: ux500: Remove platform registration of MSP devices

[Lee Jones]

This patch removes platform device registration of all 4 MSP
devices. It also takes care of all redundant infrastructure now
that each of the ux500 audio components have been Device Tree
enabled.

[PATCH 14/17] ARM: ux500: Rename MSP board file to something more meaningful

[Lee Jones]

The 'msp' board file does more than just register MSP devices. It
also registers some other components necessary to get audio working
on ux500 based platforms; such as the PCM and Machine Drivers. For
that reason we're changing the filename to be more encompassing -
'audio'.

[PATCH 15/17] ARM: ux500: Add nodes for the MSP into Device Tree

[Lee Jones]

This patch inserts all known MSP devices into the DBx5x0 Device Tree
disabled and enables the two important ones for the Snowball low-cost
development board.

[PATCH 16/17] ARM: ux500: Add all encompassing sound node to the Snowball Device Tree

[Lee Jones]

This is where we link together all of the SoC sound components for
a given platform. This all encompassing sound node is only found
in the very lowest hierarchical DTS file, since the component mix may
well change from board variant to board variant.

Ah, I see. That's what Linus was going on about!

I can do that.

Subject: [PATCH 1/1] ARM: ux500: Rename MSP board file to something more meaningful

The 'msp' board file does more than just register MSP devices. It
also registers some other components necessary to get audio working
on ux500 based platforms; such as the PCM and Machine Drivers. For
that reason we're changing the filename to be more encompassing -
'audio'.

However I'd request Ola/Roger to ACK it too on the ALSA side.

Please don't send contentless top-posted pings - if you think things
have been forgotten you should generally resend them, there's a good
chance that if things have been lost people don't have the original any
more.  Replying means the patch is quoted so is painful to apply if
anyone wants to test (or otherwise apply the patch) and top posting is
generally frowned upon.

I'm no DT-expert, but why are you adding MSP-stuff in the machine-driver? They
are also added in the next patch.

This parameter has nothing to do with the ASoC platform-driver. Some way or the
other the earpiece-cmv should belong to the codec-driver. Also, this parameter
was set in the previous patch as well?!

This is context for the example - the example is just informative and
tends to include other things so they can be referenced by the main bit
of the example, it's the documentation at the top that's the bindings
themselves.

You know that this is just a documentation patch right?

It just shows how the pieces fit together. No settings will actually
be read from here, it's just a .txt file used for reference.

Kind regards,

This is a documentation file. Duplication is not important, as it's only there
for reference.

This isn't the ab8500-codec documentation. For valid earpiece values please
see the documentation in patch "Documentation: Add the AB8500 CODEC device
to the MFD AB8500 doc"

Apart from these comments does the patch looks okay?
