Hi PXA maintainers,
I'm in the process of getting the old ARM platforms to all build
in a single kernel. The largest part of that work is changing all
the device drivers to no longer require mach/*.h header files.
This series does it for arch/pxa/.
As with the omap1 and s3c24xx series I sent before, I don't
expect this all to be correct in the first version, though
a lot of the patches are fairly simple and I did exhaustive
compile-time testing on them.
Please test if you have the hardware, or review!
Arnd

The mach/hardware.h is included in lots of places, and it provides
three different things on pxa:
- the cpu_is_pxa* macros
- an indirect inclusion of mach/addr-map.h
- the __REG() and io_pv2() helper macros
Split it up into separate <linux/soc/pxa/cpu.h> and mach/pxa-regs.h
headers, then change all the files that use mach/hardware.h to
include the exact set of those three headers that they actually
need, allowing for further more targeted cleanup.
linux/soc/pxa/cpu.h can remain permanently exported and is now in
a global location along with similar headers. pxa-regs.h and
addr-map.h are only used in a very small number of drivers now
and can be moved to arch/arm/mach-pxa/ directly when those drivers
are to pass the necessary data as resources.

The mach/mfp.h header is only used by this one driver
for hardcoded gpio numbers. Change that to use a lookup
table instead.

There are two different ways of flushing the ac97 queue
in this driver, selected by a compile time option.
Change this to a runtime selection to make it work when both
are enabled.

The two drivers are almost identical and can work on a variety
of hardware in principle. The mainstone driver supports additional
hardware, and the zylonite driver has a few cleanup patches.
Sync the two by adding the zylonite changes into the mainstone
one, and checking for the zylonite board to order to keep the
default behavior (interrupt enabled) there.

To avoid a dependency on the pxa platform header files with
hardcoded registers, change the driver to call a wrapper
in the pxa2xx-ac97-lib that encapsulates all the other
ac97 stuff.

Arnd, do you have these devices by chance? I had stached patches
converting wm97xx core to use threaded ISR and it would be great if
someone could test them...

Not supper happy about adding module dependencies. Can we include
mach/regs-ac97.h from include/sound/pxa2xx-lib.h and use static inlines?
Someone needs to include mach/regs-ac97.h in the end...
Or there is something later in the series that needs it?
Thanks.

Hi Arnd,
Would you have a git tree I can pull from ?
That would make my life easier than applying manually 46 patches...

Sorry for the duplication, I had some problems with email configuration

Unfortunately I don't, but I'm hoping that someone can test my series

One of the goals of the series is to completely remove all mach/*.h headers
and place them somewhere else, ideally inaccessible to device drivers.
In case of mach/regs-ac97.h, the later patch "ASoC: pxa: ac97: use normal
MMIO accessors" passes the physical register base address as a platform
device resource that gets ioremapped in the ac97 driver, rather than
hardcoding the virtual address in a global header.
I agree that the exported function is still ugly, but I hope it's enough of
an improvement over the previous state that we can do it anyway.
If you have any better ideas though, I can give that a try, too.
One possibility would be a higher-level interface exported on top
of 'struct snd_ac97', but I could not figure out how to do this.

No, I do mot really have better ideas given your stated goals and I
guess there is not really much benefit on spending too much effort
polishing essentially one driver.

I don't get very far.
$ make-arm pxa_defconfig
arch/arm/Kconfig:677: can't open file "arch/arm/plat-pxa/Kconfig"
scripts/kconfig/Makefile:90: recipe for target 'pxa_defconfig' failed
make[1]: *** [pxa_defconfig] Error 1
Makefile:567: recipe for target 'pxa_defconfig' failed
make: *** [pxa_defconfig] Error 2
$ git describe
v5.4-rc3-52-gfcc4181cd625
Also:
$ git grep plat-pxa
Documentation/arm/marvel.rst: arch/arm/plat-pxa
Documentation/arm/marvel.rst: arch/arm/plat-pxa
Documentation/arm/marvel.rst: directory. The plat-pxa/ would therefore disappear.
arch/arm/Kconfig:source "arch/arm/plat-pxa/Kconfig"
arch/arm/mach-mmp/Makefile:ccflags-$(CONFIG_ARCH_MULTIPLATFORM) := -I$(srctree)/arch/arm/plat-pxa/include
drivers/gpio/gpio-pxa.c: * linux/arch/arm/plat-pxa/gpio.c
drivers/soc/pxa/mfp.c: * linux/arch/arm/plat-pxa/mfp.c
Did I pick the wrong tree ?

It seems that one line got lost in a rebase and ended up in a different patch
that was not part of the series. I updated the git tree now.

Ok Arnd, I have a preliminary test report.
I tested only the pxa27x (mioa701), which happens to have a lot of drivers, and
only the platform_data flavor (ie. no device-tree test yet). Apart a panic in
the regulator framework (which is a known issue [1]), your version seems
equivalent so far in terms of runtime to Linux 5.4-rc3).
The sound and RTC seem broken, but not by you ...
I'll continue the test onwards for pxa3xx and pxa2xx when I'll gather a bit of
time, and try to review as well the mach-pxa part.
Cheers.

For the pxa part, that looks fine to me.
I'd like to focus a bit of Russell's attention to the sa11xx part (reminder in
[1]), and more specifically :
- the change to drivers/pcmcia/soc_common.c
- the change to drivers/pcmcia/sa1111_generic.c
I must admit my knowledge of PCMCIA is relatively poor, and even if the patch
looks harmless, one never knows if Assebet will ever by same after ...
Cheers.

I don't understand that part, why do you check for a zylonite board in this file
?

What I tried to do with code like this, when I was ambitious,
was to wind out mfp_to_gpio() as well and either just encode
the offset on gpio-pxa as a define locally.
But this works too, the kernel looks better after than before
and I am not perfectionist, so:

Revisiting another old patch. The reason here is that both the zylonite and
mainstone drivers are for the same hardware, using the same "wm97xx-touch"
platform_driver name, which means that we cannot have them both built
in the same kernel on a multiplatform machine.
By making the mainstone driver deal with zylonite hardware, we can
ensure that this driver works on all the relevant machines. I'm fairly sure
my plan was to later remove the zylonite driver entirely, but for some reason
I did not include a patch for that in my series.
We can probably do that as a follow-up later.
