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

2.20.0
The audio device is allocated by the audio driver, and it uses a gpio
number from the mach/z2.h header file.
Change it to use a gpio lookup table for the device allocated by the
driver to keep the header file local to the machine.

The audio driver should not use a hardwired gpio number
from the header. Change it to use a lookup table.

2.20.0
To avoid dereferencing hardwired constant pointers from a global header
file, change the driver to use devm_platform_ioremap_resource for getting
an __iomem pointer, and then using readl/writel on that.
Each pointer dereference gets changed by a search&replace, which leads
to a few overlong lines, but seems less risky than trying to clean up
the code at the same time.

In a multiplatform kernel that includes both pxa and mmp, we get a link
failure from the clash of two pxa_register_device functions.
Rename the one in mach-mmp to mmp_register_device, along with with the
rename of pxa_device_desc.

The driver should not require a machine specific header. Change
it to pass the gpio line through a lookup table, and move the
timing generator definitions into the drivers itself.

I'm not overly confident that I got the correct device names
for the lookup table, it would be good if someone could
double-check.

Aside from this, keep the changes to a minimum.

2.20.0
The driver needs some low-level register access for setting
the core and bus frequencies. These registers are owned
by the clk driver, so move the low-level access into that
driver with a slightly higher-level interface and avoid
any machine header file dependencies.

The sa1111.h header defines some constants using the bitfield
macros, but those are only used on sa1100, not on pxa, and the
users include the bitfield header through mach/hardware.h.

2.20.0
To avoid dereferencing hardwired constant pointers from a global header
file, change the driver to use devm_platform_ioremap_resource for getting
an __iomem pointer, and then using readl/writel on that.
Each pointer dereference gets changed by a search&replace, which leads
to a few overlong lines, but seems less risky than trying to clean up
the code at the same time.

2.20.0
The clock register definitions are now used (almost) exclusively in the
clk driver, and that relies on no other mach/*.h header files any more.
Remove the dependency on mach/pxa*-regs.h by addressing the registers
as offsets from a void __iomem * pointer, which is either passed from
a board file, or (for the moment) ioremapped at boot time from a hardcoded
address in case of DT (this should be moved into the DT of course).

2.20.0
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.

The battery driver uses a lot of GPIO lines, hardcoded from a
machine header file.
Change it to use a gpiod lookup table instead.

get_clk_frequency_khz() is not a proper name for a global function,
and there is only one caller.
Convert viper to use the properly namespaced
pxa25x_get_clk_frequency_khz() and remove the other references.

Change this to a runtime selection to make it work when both

The driver traditionally hardcodes the MMIO register address and
the GPIO numbers from data defined in platform header files.
To make it indepdendent of that, use a memory resource for the
registers, and a gpio lookup table to replace the gpio numbers.

The driver was written as a "common" driver that could
be shared between platforms, but it was never actually shared
and now written in a completely portable way either, so just
move it into the platform to avoid header file dependencies.
Unfortunately, this driver uses the DMABOUNCE feature, which
is likely to cause problems in a multiplatform configuration,
need to investigate further. Apparently the cm-x255 only
has 64MB of RAM and does not need bouncing, but the cm-x270
can have anywhere between 32MB and 128MB, which is where
we exceed the 64 MB of address space in the chip.
Another problem is the ARCH_HAS_DMA_SET_COHERENT_MASK flag,
which messes up other PCI implementations.

There are two identical copies of mach/bitfield.h, one for
mach-sa1100 and one for mach-pxa. The pxafb driver only
makes use of two macros, which can be trivially open-coded
in the header.

2.20.0
The poodle audio driver shows its age by using a custom
gpio api for the "locomo" support chip.
In a perfect world, this would get converted to use gpiolib
and a gpio lookup table.
As the world is not perfect, just pass all the required data
in a custom platform_data structure. to avoid the globally
visible mach/poodle.h header.

Only one declaration from this header is actually used in drivers,
so move that one into the global location and leave everything else
private.

Lubbock is the only machine that has three IRQs for the UDC.
These are currently hardcoded in the driver based on a
machine header file.
Change this to use platform device resources as we use for
the generic IRQ anyway.

2.20.0
The three eseries machines have very similar drivers for audio, all
using the mach/eseries-gpio.h header for finding the gpio numbers.
Change these to use gpio descriptors to avoid the header file
dependency.
I convert the _OFF gpio numbers into GPIO_ACTIVE_LOW ones for
consistency here.

The magician audio driver creates a codec device and gets
data from a board specific header file, both of which is
a bit suspicious. Move these into the board file itself,
using a gpio lookup table.

2.20.0
There are two tavorevb boards in the kernel, one using a PXA930 chip in
mach-pxa, and one using the later PXA910 chip in mach-mmp. They use the
same board number, which is generally a bad idea, and in a multiplatform
kernel, we can end up with funny link errors like this one resulting
from two boards gettting controlled by the same Kconfig symbol:
arch/arm/mach-mmp/tavorevb.o: In function `tavorevb_init':
tavorevb.c:(.init.text+0x4c): undefined reference to `pxa910_device_uart1'
tavorevb.c:(.init.text+0x50): undefined reference to `pxa910_device_gpio'
tavorevb.o:(.arch.info.init+0x54): undefined reference to `pxa910_init_irq'
tavorevb.o:(.arch.info.init+0x58): undefined reference to `pxa910_timer_init'
The mach-pxa TavorEVB seems much more complete than the mach-mmp one
that supports only uart, gpio and ethernet. Further, I could find no
information about the board on the internet aside from references to
the Linux kernel, so I assume this was never available outside of Marvell
and can be removed entirely.
There is a third board named TavorEVB in the Kconfig description,
but this refers to the "TTC_DKB" machine. The two are clearly
related, so I change the Kconfig description to just list both
names.

2.20.0
There are two drivers in arch/arm/plat-pxa: mfp and ssp. Both
of them should ideally not be needed at all, as there are
proper subsystems to replace them.
OTOH, they are self-contained and can simply be normal
SoC drivers, so move them over there to eliminate one more
of the plat-* directories.

We have three power supplies that need similar initialization.
As a preparation for the gpio lookup table conversion, split
out the initialization into a separate function.

for hardcoded gpio numbers. Change that to use a lookup

2.20.0
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.

a header file that we want to eliminate. Change it to use
the mmio resource instead and stop including the heare.

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
on any hardware they might have.
If you like, send me your patches and I'll add them to this series.

If the series doesn't make it into 5.5, I can also apply

In fact, I'd love to see more non-DT boards go from mach-mmp. There are
good indications nobody is looking after MMP2-based "Jasper", "Flint"
and "Brownstone" and they probably weren't seen outside Marvell either.
The latter has a DTS file.
Would anybody miss them?
Thanks

Probably not, but I had a hard time identifying any boards in mmp
and some other platforms that are actually worth keeping.
Back in the days, a common way the platforms were maintained
was to only have the official development board in mainline Linux,
while many products were left with out of tree board files.
This means it's impossible to see which SoCs actually got used
in the field and which ones did not. It also means the other
machines stopped getting forward-ported and nobody could test
the mainline changes.
I wouldn't mind just removing all of the machines that were clearly
reference hardware rather than actual products unless we know of
someone still using them.
In case of MMP, that doesn't leave a lot though, the gplugD is the
only one that clearly meant as an end-user product. I'd also leave
all the DT based platforms as a rule, mainly because the DT has
made it possible to support additional boards with a custom dt blob
and no kernel changes.
If you have any more insight into what particular boards actually
were used for, and which ones can get removed, that would
be very welcome.

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.

Please submit patches using subject lines reflecting the style for the
subsystem, this makes it easier for people to identify relevant patches.
Look at what existing commits in the area you're changing are doing and
make sure your subject lines visually resemble what they're doing.
There's no need to resubmit to fix this alone.

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.

This last one looks a bit dubious, as it looks like a gpio on a gpio expander,
could you cross-check that "gpio-pxa" shouldn't be an I2C expander gpio please ?

That curious, because you divide here by 10^4, while in the old
pxa2xx_pcmcia_set_mcxx() that was 10^3 ... is that a fix I don't see ?

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.

This patch bothers me a bit.
The idea behind generic.c is that it's a file common to all pxa2xx, pxa3xx
platforms. Yet with this patch, someone without history will believe that
calling pxa_smemc_get_sdram_rows() on a pxa3xx platform is perfectly valid,
while it is not, because DRAC2 doesn't exist on pxa3xx (bits are not defined in
MDCNFG).
At least I'll rename the function to pxa2xx_smemc_get_sdram_rows() if you don't
have a better idea.
Cheers.

This is consistent with the way I imagine it should be done so:

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:

You're anyway doing more than required for the people who
may or may not be using this platform. Brokenness can surely
be fixed later, it's not like we are taking down the entire Amazon
cloud or something.

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.

I'm revisiting this older patch series now, this was clearly a mistake
in my original
version, changed it now to
@@ -982,7 +982,7 @@ static struct gpiod_lookup_table akita_audio_gpio_table = {
"mute-l", GPIO_ACTIVE_HIGH),
GPIO_LOOKUP("sharp-scoop.0", SPITZ_GPIO_MUTE_R -
SPITZ_SCP_GPIO_BASE,
"mute-r", GPIO_ACTIVE_HIGH),
- GPIO_LOOKUP("gpio-pxa", AKITA_GPIO_MIC_BIAS -
AKITA_IOEXP_GPIO_BASE,
+ GPIO_LOOKUP("i2c-max7310", AKITA_GPIO_MIC_BIAS -
AKITA_IOEXP_GPIO_BASE,
"mic", GPIO_ACTIVE_HIGH),
{ },
},
I'm not 100% sure this is the correct name, as I don't fully
understand how i2c device
names are constructed. I see that Linus added a device name in commit
32d1544880aa ("ARM: pxa: Add gpio descriptor lookup tables for MMC CD/WP"),
and I guess I could do the same here, but I think that was only needed
to disambiguate
two instances of the same device in zylonite, which is not needed for spitz.

Revisiting an older patch here: I'm fairly sure the change was my typo,
fixed it now, thanks!
