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.

Rather than relying on machine specific headers to
pass down the reboot status and the register locations,
use resources and platform_data.
Aside from this, keep the changes to a minimum.

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

Generally speaking, platform_device_register_simple() is better than
platform_add_devices(), it does the same thing with fewer source lines
and smaller object code, and it doesn't have the problem of lifetime rules
for statically allocated reference-counted devices.
One day we may want to replace all static platform_device instances with
platform_device_info instead, but right now there are too many of those.
I can change this one to a platform_device for consistency though if you
think it's worth it.

No, I was just wondering. Thanks for the explanation.

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.

Awesome, thanks for testing so far and for the report!

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.
