ARM: pxa: add support for Raumfeld audio devices

ARM: pxa: add support for Raumfeld audio devices

[Daniel Mack]

Hi,

Here is a series of 17 patches to support the multiroom audio devices
produced and sold by Raumfeld. The kernel is based on mainline, and all
other pieces needed by these devices have already been submitted over
the last months.

What was still missing is the board support code which I would like to
let it life in the mainline git, too. The series is based on top of
Eric's pxa-devel tree.

For more information about the hardware, see http://www.raumfeld.com/en/

If that's still possible, I'd be happy if they could make it to 2.6.33.

Please note that one patch depends on the MAX8660 power regulator driver
which I cherry-picked in my tree. As there's need for a special include
file, I don't know what the best way would be to avoid build breakage.
Maybe queue it for 2.6.33-rc2, after the regulator tree has been merged?

Daniel

This should be in the board file under arch/arm.

This should be in a proper header file somewhere.

Remove this and the other empty functions.

It might be a bit more legible to have some constants for the arguments
for this function - it's not entirely clear what's going on, the 1 and 0
look like a boolean but that's not what's really going on here.  It may
be better to do this as a proper driver, there was at least one driver I
remember being posted for a TDM clock generator which I think got
merged.

I don't know what about others, but I find it difficult to follow too many small
patches. I'd personally prefer to have

This looks like you want to add regulator support to the CODEC.

The relevant drivers really need to know about this...  if you are going
to stick with this approach I'd push all this stuff into the audio
driver, splitting it into this separate file isn't really buying
anything since it's all machine specific and nothing except the audio
driver needs to know what's going on.

The regulator consumer stuff here feels like it'd be better put into the
driver itself since it doesn't seem to be specific to the machine -
other machines could use the same glue with different machine setup.

Don't do this, take one reference to the regulaor at startup and then
use that throughout the lifetime of the sysetm.  If you don't do that
then the API may decide that the regulator is idle and disable it for
you.

I suspect that supply name might want to be just plain "vcc" unless the
chip really does have a single supply labelled as vcc_wifi - the name
should ideally match that used in the datasheet.

Nack, if you're doing regulator_get() you should never need to check
regulator_is_enabled() since you can't know if something else is
incrementing or decrementing the reference count independantly of you.
Either use regulator_get_exclusive() (at which point you own the
regulator) or keep track of the on/off switch yourself.

It'd be better to do this before enabling the regulator to ensure that
the regulator comes up with the appropriate supply voltage set and
doesn't upset the chip.

Well, I was told it is a lot easier to review patches when they're
split up in smaller pieces. However, I would be fine if they are
squashed when merged :)

Well, the problem is that if I do it there, I don't get a handle for the
actual data transfer, which I now get from i2c_new_device(). There is no
driver matching this device (it wasn't taken because it's 'too simple').

How would I get a handle to pass to i2c_master_send() or an equivalent

Hmm, I thought so too, but it would be the only thing to add there.
Hence I decided to not do that. You really prefer that?

Well, that's not really a regulator but just a GPIO that drives a FET.
Doesn't using the regulator framework seem a little overdone?

The idea was to only let the board support file know about GPIO
definitions, so the audio part doesn't need to know about the details.
But I can move that if you like. However, I don't see much benefit - I
would merely just move the whole function over.

AH, the pxamci driver already does that. So I'll just name the supply
'vmmc' and that's it. Will test that soon.

The issue I was facing here was that the mmc power enable callback was
called more than once with the same value for 'on', so the calls were
not balanced and the regulator driver bailed.

Anyway, that will all go away when letting the driver do the regultar
calls. Thanks for explaining that.

No, the main goal here is to make sure the CODEC driver knows what's
going on with its power.  In your system it is a trivial GPIO based
regulator that's doing the power control but other systems might have
something different.  Looking at it from the other angle, nothing about
powering on and off the CODEC ought to be board specific.

I do also have a plan in the back of my mind to use the runtime PM
infrastructure to allow ASoC to push things down into BIAS_OFF when
they're idle rather than just BIAS_STANDBY which this won't play well
with.

The audio driver is already entirely board specific, knowing about the
GPIOs isn't going to make any odds here.  At the minute reading the
code it looks like part of the audio driver has randomly been lifted out
into a separate file for no particular reason.

If nothing else it'll fix the extern in a .c file issue.

There was at least one unrelated driver for a different part - I
remember the discussion since someone needed to explain to people (Alan
Cox, I think) that this wasn't an RTC but rather a TDM clock generator.

Looking at the thread in the archive I don't see any effort to answer
Jean's question there - the reply from Jon talks about device tree
binding which is, as Jean says, pretty much irrelevant to the question:

   http://marc.info/?l=linux-i2c&m=122465761327694&w=2

The question seemed to be more about what the driver was supposed to
accomplish - talking about the functionality is provided by the driver
once it's bound to the device should address that.

If you use regulator_get_exclusive() then your usage is OK since other
users can't collide with your usage, otherwise you'd need to remember
the state in your driver if the caller isn't giving you balanced
enable/disable calls.

Ok, just to make sure I get you right: the idea would be to add a simple
regulator and label it in a way so that the codec driver will be able
to take control? And then claim that regulator from cs4270.c?

I guess "reg-fixed-voltage" would be the appropriate driver?

gpio_request may fail, thought it's unlikely to happen. Anyway, adding check for
it's return value seems to be a good practice.

I failed to follow what peripherals are common to what boards, but after
applying all the patches it seems that all three _init functions are really
similar. Have you considered having one _init function for all three machines
and calling machine-specific init based on machine_is_X?

Wouldn't it be better to keep mfp tables for common pins and each of board
variants rather than configure mfp for particular interface? This applies for
other patches that have
+	pxa3xx_mfp_config(ARRAY_AND_SIZE(raumfeld_<something>_pin_config));
as well. :)

Any reason to keep the devices array inside the function? I think it makes the
code less readable.

Wouldn't it be nicer to group all the pxa_set_* calls together?

Ok, I squashed most of the commits together for the next round so make
hat easier :)

Ok, I put BUG_ON() around them. I see no reason to care for proper error
handling as this is not a driver. If any of those functions fail in the
low-level code, there is something seriously broken.

Yes, I did consider that. But eventually, they are a) all not big and b)
too different. Doing the way you suggest make it look more messy. Have a
look at the second round and tell me if you stick to your opponion :)

Thanks for your input,

I had it that way, but the idea is to prevent double definitions. What
we have now is a config for all pins needed by the ethernet device, and
each machine which needs that just references it. It looks more straight
forward this way, but eventually that might be a matter of taste :)

Unless anyone has a strong opinion abouth that, I'd like to keep it as
it is now.

Well if the gpio_request fails here, you are doomed anyway. There's nowhere to 
return to. But it's a good idea to fail and don't try to request other GPIOs.

How about just having each board setup all MFP configuration at boot time
and be done with it - yes, it'll mean some duplication for the pins which
are common, but at least you know when looking at board N how all the pins
are configured.

Also, non-static initialized structures and arrays inside functions are
a waste of space.  You might as well write it like this, because the
following is exactly what the compiler will be doing for you:

static const struct platform_device *__raumfeld_controller_devices[] = {
	&rotary_encoder_device,
};

static void __init raumfeld_controller_init(void)
{
	struct platform_device *raumfeld_controller_devices[ARRAY_SIZE(__raumfeld_controller_devices)];
	memcpy(raumfeld_controller_devices, __raumfeld_controller_devices, sizeof(__raumfeld_controller_devices));
	...
}

Shouldn't you be using msleep() here?  schedule_timeout() can terminate
prematurely, particularly if there's a signal pending.  msleep() will
wait for the full timeout.

Not entirely true.  If a gpio request fails because somehow it was claimed
by something else, that doesn't mean other stuff will also fail.  Also,
don't think that if a gpio_request in such a function fails you have to
exit from it.

A good idea is to do this:

	ret = gpio_request(gpio, name);
	if (ret)
		printk(KERN_ERR "Myplatform: gpio%u(%s) request failed: %d\n",
			gpio, name, ret);

Even better:

static void claim_gpio_output(int gpio, const char *name, int value)
{
	int ret = gpio_request(gpio, name);
	if (ret) {
		printk(KERN_ERR "Myplatform: gpio%u(%s) request failed: %d\n",
			gpio, name, ret);
	} else {
		gpio_direction_output(gpio, value);
	}
}

and then you're not duplicating the multiple gpio calls.

Again, msleep() preferred.

Ok, will probably get back to this later. For now, I left the code where
it was but changed the API to make it clearer. The actual implementation
is in one line only, so I see no urgent need to move it to an own driver
immediately. Let me know if you're fine with the new version I'll post
soon.

Thanks,
Daniel

Ok, thanks. Did that now, and will repost a squashed version of the
series.
