To: linux-arm-kernel
Second part of at91rm9200 legacy !DT removal. This is the core !DT support
removal for this Atmel SoC.
Note that from now on, the Kconfig.non_dt file and its specialized options are
completely removed.
Use the Device Tree for running this board with newer kernels.

As the ARCH_AT91RM9200 is removed because being !DT, we use
the SOC_AT91RM9200 variant. This option can certainly be removed
once the ST driver is reworked a bit.

OLD_CLK_AT91 & OLD_IRQ_AT91 were only selected by entries in Kconfig.non_dt
that are now gone. So we remove all this legacy stuff and select the proper
options in the SOC_ entries.
As USE_OF is now selected directly in arch/arm/Kconfig AT91 entry, we can
safely remove it everywhere in this file.

As the CONFIG_OLD_CLK_AT91 option is gone, let's completely remove the AT91
old clock driver related data.

All clocks and the clock trees for all Atmel SoCs are now described by drivers
using the common clock framework.

Remove irc.c and associated header file. The related code was idendified by
the CONFIG_OLD_IRQ_AT91 option that was removed previously. It has been spotted
by following coccinelle semantic match:
@rule1@
expression E;
statement S;
@@
(
- if (IS_ENABLED(CONFIG_OLD_IRQ_AT91)) S
|
- if (IS_ENABLED(CONFIG_OLD_IRQ_AT91) && E) S
)

Julia,
This is my very first try of coccinelle so forgive my naivety. But I would like
to know how you would have done that.
Note as well that the 3 little chunks concerned by the use of coccinelle would
have perfectly been removed by hand, but I wanted to have a try ;-)
Thanks, best regards.
Nicolas

I would have done:
@@
statement S1,S2;
@@
*if (IS_ENABLED(CONFIG_OLD_IRQ_AT91) && ...)
S1 else S2
There are a lot of things going on here:
1. The * in column 0 means just search for something. It will seem to be
-'d in the result, but having * in the specification seems a bit nicer.
2. To be exhausitve, maybe some relevant code has an else. When an if
pattern has an else pattern that is just a metavariable that is not used
elsewhere, it also considers the possibility that the else is empty, and
thus missing completely. This is called an isomorphism. The available
isomorphisms are described in the file standard.iso.
3. xxx && ... matches 0 or more occurrences of && with xxx at top level.
So it subsumes the two patterns you provided.
4. Another isomorphism will flip the branches of the if and negate the
condition. Here that should match a || pattern. On the other hand, in
your case that will not be quite good enough, because it will be an ||
pattern with !IS_ENABLED, not IS_ENABLED. So to be really complete you
should put another rule with || rather than &&.
Thanks for trying Coccinelle!

Since 3b26f39b0ab1 (ARM: at91: make use of the new AIC driver for dt enabled
boards) the old IRQ initialisation functions aren't used anymore: remove their
declaration in generic.h.

Awesome stuff!
Two questions:
- is anything holding this up from getting merged in 3.19?
- Are there any remaining issues that keep us from using multiplatform?
I know you all have been working on those a lot, but I haven't
checked what is still missing.

If you think this is not too late in the cycle, I would say go ahead ;)

As discussed some weeks ago, I prepared patches to switch sama5d[3-4] to
multiplatform. We are still missing the SMC and matrix drivers to switch
sam9 and rm9200.
The currently affected drivers are:
- drivers/ata/pata_at91.c (SMC)
- drivers/pcmcia/at91_cf.c (SMC)
- drivers/usb/gadget/udc/at91_udc.c (Matrix, this is the only one
for sam9)
- sound/atmel/ac97c.c (that one is still not converted to DT anyway...)
- drivers/watchdog/at91rm9200_wdt.c (WIP, will be converted properly to
an MFD)
I'll resume working on that in December.
Do you want me to submit the sama5d[3-4] switch for 3.19? I'll have to
rebase on that series. The main remaining issue is that I couldn't work
out a way not breaking the defconfigs, even after talking with the
Kconfig maintainer so doing first sama5 then sam9/rm9200 will break the
defconfigs for sam9/rm9200 twice.

Probably better to do all of mach-at91 at once for 3.20 so we don't break
anything trying to make both aproaches work together.

Arnd,
I am totally in favor for a merge into 3.19.
I wanted to wait one day or two but given that the official announce had
been made several months ago, I don't think it makes a big difference.
So, what do you prefer:
1/ I wait today and send you the pull-request this evening (our time)
2/ I send you the pull-request at the beginning of next week but still
can make it for 3.19?
(BTW, in the meantime, there is a pending pull-request (at91-cleanup3)
but it is true that you needn't pulling it in if you plan to take this
one which will be named at91-cleanup4 and that will obviously contain
the 3rd one).

Just send the pull request whenever you have it ready. If some bug shows
up, reply to that mail with an updated pull request.

Yes, I have a backlog of pull requests to look at, should get to that soon

I just looked at the drivers because I got curious, and to see if
there are still any low-hanging fruit, but I guess you already picked
them all ;-)

I guess the SMC should live in drivers/memory with an interface
similar to mvebu-devbus.c?
Seems doable but nontrivial.
> - drivers/usb/gadget/udc/at91_udc.c (Matrix, this is the only one
> for sam9)
Is at91_matrix a pin controller? With the board files removed, the udc
driver has the only two remaining calls to at91_matrix_{read,write}
for setting the pullup, so that could be modeled as a trivial pinctrl
driver
> - sound/atmel/ac97c.c (that one is still not converted to DT anyway...)
This one seems fairly straightforward to do, including a DT binding,
but the result is still ugly as it supports the at32 chips that
do things very differently.
The patch below gets it to compile and should be enough as a replacement
once a compatible string gets added.
> - drivers/watchdog/at91rm9200_wdt.c (WIP, will be converted properly to
> an MFD)
I think we discussed this one before. Remind me why we can't just convert
it to use watchdog_register() for simplification and then move whatever
remains into the arch/arm/mach-at91/at91rm9200_time.c file, or both
into drivers/clocksource.

ASoC: atmel/ac97c: remove platform_data dependency
As at91 gets changed to multiplatform, we can't use the mach/cpu.h
header any more, but this is ok as it only gets used to check for
cpu_is_at32ap7000(), which arch/avr32.
In order to make the driver work without platform_data, this also
changes the reset gpio line handling so it can look up the gpio
descriptor from DT. It is still missing a compatible string and

Actually, there's some work in progress to support the EBI/SMC blocks
as a memory controller driver ;-):
http://thread.gmane.org/gmane.linux.kernel/1822096
I'll post a new version soon.

The matrix block is containing several system configuration registers.
Most of them are related to AHB/APB bus config (master <-> slave
priority, burst and some other configs I don't remember).
Another register is here to define which HW logic is attached to an
external device connected through the EBI (External Bus Interface):
NAND, SDRAM, CompactFlash, ...
And, as you pointed out, there's a register to configure the pullup of
the UDC device.
As you can see, the matrix registers might be accessed by different
drivers (include the EBI/SMC driver), hence I proposed to expose them as
a syscon device (see the EBI/SMC series).
Best Regards,
Boris

Yeah, my main goal was to test multiplatform on sama5d3 and it was
actually quite easy. The worst still being rm9200 ;)

Actually, some work was done but we never saw an other version of the
series. Alexander, are you still interested? Else we can take the patch
below.

Yeah, the new plan is to merge the watchdog with at91rm9200_time.c and
move it either to drivers/clocksource or make an mfd. I believe the
former would be easier.

Well, I tried to get a ac97c driver based on alsa soc framework as suggested
by Takashi. But I failed so far, I could not get my head around those
architecture.
When keeping my DT support on the current driver, the only thing which is open
that the bindings should be modifed that they are like soc-ac97link bindings.
I could work on that, but I currently don't know when I can get access again
to that hardware for testing.
Best regards,
Alexander

I see. Yes, the approach is similar, and there are actually multiple
independent problems:
- getting the current driver to build with multiplatform (trivial, 5 lines)
- changing the gpio handling to work with DT (simple, both of us did that)
- writing the binding (simple)
- changing the driver to ASoC (not that simple)
> Well, I tried to get a ac97c driver based on alsa soc framework as suggested

Let's just start with the trivial first patch, that can probably just be merged
into 3.19, and then we can build on top of that later if anybody wants to
get ac97 working again on at91.

Makes sense, if that binding works on the at91 hardware. I'm not sure
whether the pinctrl stuff or the first two gpio lines apply though.

8<---
ALSA: atmel: fix building the ac97 driver for at91-multiplatform
at91 will no longer export the mach/cpu.h and mach/hardware.h header files
in the future, which would break building the atmel ac97c driver.
Since the cpu_is_* check is only used to find out whether we are running
on avr32 or arm/at91, we can hardcode that check in the ARM case.
Unfortunately the driver is missing other work to be useful again on ARM,
if anyone wants to actually use it, they need to add a DT binding, and
the driver should really be converted to use the ASoC framework.

Yeah, let's focus on those first steps. Takashi was willing to take
patches, even if we were not converting the driver to ASoC.

Do you want one of us to send that patch to Takashi and the Alsa ML or
will you do it?
You can add my ack.
