[PATCH 02/20] ASoC: S3C: I2Sv2: Reject immidiate register value

[Jassi Brar]

Towards generalizing CPU driver interface, do not accept direct field
values for the BCLK and RCLK.
The machine driver should simply request the FS-multiple and not provide
the value to be set in divide field of IISMOD.

[PATCH 03/20] ASoC: S3C64XX: I2S: Make BCLK independent of sample size

[Jassi Brar]

For some CPU-CODEC and source clock combination we might need to set
BCLK to N*Sample_size*LRCLK, where N may be even 3 or 4, not just 2.

We can simply remove the dependency of BCLK on sample size as there
is already a callback(S3C_I2SV2_DIV_BCLK) available to set required BCLK.

[PATCH 04/20] ASoC: S3C: I2Sv2: Remove S3C_IIS_V2_SUPPORTED define

[Jassi Brar]

The code in s3c-i2s-v2.c is compiled via Makefile and not implicitly
by include'ing. Also, the driver developer anyways has to refer to the
manual to see if the code can be reused for the SoC under consideration.
That makes the S3C_IIS_V2_SUPPORTED retrospective rather than a check.

Towards having build for multiple SoCs segregate hw_params callback
for s3c2412 and s3c64xx.
Since, all new SoCs have s3c64xx like register map, we keep that as
default implementation if no SoC specific callback is already defined.

[PATCH 10/20] ASoC: S3C: I2Sv2: Move register definitions closer to driver

[Jassi Brar]

The header for I2Sv2 (linux/arch/arm/plat-s3c/include/plat/regs-s3c2412-iis.h)
contains only controller specific definitions and nothing SoC specific. So, it
could be moved to sound/soc/s3c24xx/
That will also help avoid delays in accepting patches that touch ASOC and ARCH
parts.

For now, we simply copy to regs-i2s-v2.h without any material changes, and render
the regs-s3c2412-iis.h useless in the kernel.
A separate patch will be submitted to S3C ARCH tree to remove the regs-s3c2412-iis.h

[PATCH 12/20] ASoC: S3C2412: I2S: Debug IMS field

[Jassi Brar]

The IMS field of s3c2412/13 is essentially the same as that of s3c64xx.
That is, the IISMOD[11] bit decides Master/Slave mode and IISMOD[10] bit
selects source clock for signal generation.
For that reason, remove improper defines for IISMOD[11:10] field mask
and define two 1bit fields that can be set independent of each other.
As a consequence, corresponding fields for PLAT_S3C64XX too get to use
these new defines.

[PATCH 15/20] ASoC: S3C: I2Sv2: Unify i2s_get_clock callback

[Jassi Brar]

Now that we have two callbacks s3c2412_i2s_get_clock & s3c64xx_i2s_get_clock
doing exactly the same thing, we can define one generic s3c_i2sv2_get_clock
and discard other two copies. Also, switch the users to make calls to the
newly defined and generic s3c_i2sv2_get_clock

[PATCH 17/20] ASoC: S3C: I2Sv2: Define new field for controller features

[Jassi Brar]

In order to make s3c-i2s-v2.c manage controllers with minor
quirks and variation in features, we define a per-block flag
that indicates the availability/lack of a particular feature
to the s3c-i2s-v2.c

While adding support for new SoCs' I2S, check for the blocks
of older SoCs that have similar feature and set the flag for
that feature.

feature in controller specific code and detecting that flag in the

[PATCH 19/20] ASoC: S3C64XX: IISv4: Add CPU driver

[Jassi Brar]

Add the CPU driver for the IISv4 block found on S3C6410.
For now, the driver is almost a copy of s3c64xx-i2s.c but
it should diverge as more IISv4 specific stuff is added.

[PATCH 20/20] ASoC: SMDK64XX: Switch to IISv4 CPU driver

[Jassi Brar]

Switch the MACHINE driver to use IISv4 CPU dai.
Remove BROKEN dependency now that we have proper CPU driver available.
Also, disable build for SMDK6400, since the S3C6400 doesn't have IISv4
controller.

Will the driver actually probe with mainline?

It seems retrograde to add this rather than using the platform data
callback that you added.  We'll need some arch/arm changes for the
driver to probe anyway so it't not a big deal to add the dependency.

I know, but that way I would have had to wait on S3C ARCH tree reflect
the patch(for which s3c64xx-i2s.c depends already).
When my latest ARCH patches are visible in your tree, we can easily switch
to using cfg_gpio in both the drivers.

...I'd suggest moving this into the patch that adds support for
CDCLKCON (or merging that patch in with this one).

Probably worth namespacing these defines a bit more (eg, S3C_IIS_) since
I'd expect they'll end up being used by the arch/arm code too in the
platform data definition.  They ought to be in include/sound or arch/arm
for visibility to arch/arm code too.

Meh, scratch that - I see where this is being used now.

For changes like this it'd be better if the changelog said something
like "Add register bit definitions for S5PC1xx" - this is all mainline
code so it's much clearer to say that this is adding support for a new
SoC.

One other thing I'd suggest is that when constructing a patch series
it'd be better to put the more invasive or controversial changes (like
moving the headers) last.  This makes it easer to apply bits of the
series if there is any controversy.

I thought of adding definitions in 'chronological order of support' in kernel
rather than SoC wise.
Ok, will divide in two patches.

I thought I already made that sure.
In my opinion, the only controversial patch was 'header-copying' and I couldn't
move that any further down the series or other changes without that.

I agree that this is the only really controversial change, but it seemed
like pretty much all the changes that added stuff to the headers or used
them could've been done pre-move so that they didn't depend on it.

Not sure which patch you point, but it was decision of logical
build-up and successful
compilation after each patch that made the patch series as it is now.

Pretty much all of them - for example, patch 11 adds a bunch of new
bitfield definitions to the header.  This change didn't really need the
header to have been moved before it was made, it could have been done
pre-move.  Keeping things building is important and some of the changes
that affected both S3C24xx and S3C64xx might've needed the move for that
but not all of them.

Dear that wud have defeated the very purpose of header moving -- don't wanna
depend on changes surfacing via ARCH tree after too long.

Right, but the header move is itself an arch change so you're blocked on
one anyway until it goes in :/

I'd ack a patch moving this in one go since there shouldn't be any

This is OK but appears to depend on one or more of the other patches

Actually it does apply - patch 3 hadn't actually made it into the queue
I was applying and that was the dependency.  I've now got them both
applied, though they were missing from the pull I sent to Takashi
earlier so I've not pushed them up to kernel.org yet.

This is just SNDRV_PCM_RATE_8000_96000 anyway so may as well use it

Of course.
Btw, I was thinking of adding RATE_KNOT too, as it is usually possible
to achieve
'not so standard' 12000 and 24000 rates, besides the flag doesn't
'promise' anything
about availability of rates.

Yeah, _KNOT support needs more work in the core - at the minute it's
just doing a bitmask match on the standard rates and someone needs to
sit down and see how things will work when you've got two different
drivers providing the constraints.  There's not actually been much
demand for this since most people just use the standard audio rates (and
a lot of devices aren't properly rated/supported at non-standard ones)
but it'd definitely be good if you could implement it.

This code is in there for pure defensiveness - since at least the
S3C64xx and S3C24xx have slightly different register maps for the block
(the ones that are currently handled are the IISMOD master settings,
there may be more) the code needs to have explicit support for the
processors.  The goal of this block is to print a #error saying exactly
what's going on rather than just have the build fail with missing
defines in order to help make it more immediately clear to users what is
going on if they try to select a processor combination they don't know
how to handle.  

Users often have a strong expectation that the driver will just work
and so relying on them consulting the processor manual isn't always
realistic.

It may be that these differences are due to some being IISv2 and some
being IISv3 or something and could easily be handled via mandatory
platform data but since none of the documentation refers to any of this
stuff and it has to be reverse engineered we've got this system based on
build time processor selection.

The way I see it, if we keep it we will have to add every supported
SoC to the list
which is kinda redundant since that information could already be extracted from
Makefile. The list of supported SoC could be useful if we somehow knew
the future SoCs' characteristics to tell if they wud work or not, but
the developer
has to first check the Manual and see if the s3c-i2s-v2.c could be
made use of or not.
Besides, I assume 'user' to be the MACHINE driver writer and 'developer' to be
the CPU driver writer.

well, I am not sure if we should sympathize with such a developer :)

Yes, maybe some more documentation is what is needed.

I agree that the current situation sucks.  Like I say, I suspect that we
can handle this better with platform data if we knew what the
underlying changes in the blocks are but right now this is all being
reverse engineered from the datasheets which don't explicitly mention
any differences or similarities between the IIS controllers of the
various CPUs that people happen to have been able to obtain datasheets
for - you're in a much better position to be able to do something about
this than most since you have access to Samsung internal information.

What I'm saying here is that while the driver needs to have per
processor ifdefs I'd rather keep the matching plain text #error - if we
can get those removed then this block could also go but it should happen
in that order.

Thing is that people writing machine drivers will frequently try
building the driver if they're working on a SoC that isn't supported yet
- they'll see a generic Samsung IIS controller driver and so (reasonably
enough) try to use it.  The error message is there to try to make it
clearer to them that they either need to turn into a CPU driver
developer and make sure support is OK or get someone else to do the
required work.

I've applied this but I'd rather see the code changed so that the BCLK
is set automatically by default and the explict divider configuration
disables that.  This way we get the best of both worlds - most users
won't need to worry about the BCLK configuration but those that need to
configure it can do so.  An awful lot of users don't really understand
audio hardware and find having to learn about which clock rates they
need and so on a bit of a learning curve.

I was thinking of calculating all register field values within the CPU driver
and let MACHINE driver specify only general parameters of audio(as in
many CODEC drivers).
After this patch series, though.

Yes, like I say I've applied the patch as-is - this was just a
suggestion for future work and it's good to hear that you're already
planning to implement such improvements.

This is good but it needs to also update all the machine drivers that
use the direct register values.  A brief grep through suggests that the
uda134x machine and the OpenMoko machines need a look, though I didn't
actually check which DAI driver they're all using.  If nothing uses this
feature then just note that in the changelog (if the feature is unused
that's even more reason to remove it anyway).

s3c-i2s-v2.c is shared only by s3c2412 and s3c64xx.
smdk64xx_wm8580 and jive_wm8750 already use appropriate values.
Will add the note in changelog.

That's OK, I'll apply it and add the note myself - no need to resend.
Thanks for checking.

[PATCH 20/20] ASoC: SMDK64XX: Switch to IISv4 CPU driver

[Jassi Brar]

Switch the MACHINE driver to use IISv4 CPU dai.
Remove BROKEN dependency now that we have proper CPU driver available.
Also, disable build for SMDK6400, since the S3C6400 doesn't have IISv4
controller.
