[PATCH 00/26] ARM: pxa specific randconfig fixes

[PATCH 00/26] ARM: pxa specific randconfig fixes

[Arnd Bergmann]

Hi Eric (and others),

Here are lots of tiny bug fixes (and a few bigger ones)
for the pxa platform that I found by running 'make randconfig'.

Could you take a look at these and see if they make sense to
you? The majority is just for corner cases that we are not
generally interested in, except for making sure that
randconfig works, but some are regressions from a previously
working state or are for relevant configurations.

It would be nice if you could either give me an ok to put
all off them into the arm-soc tree for the coming merge window
or cherry-pick the ones that are good and send them back
to me in a pull request.

The series is also available in git at
 git pull git://git.linaro.org/people/arnd/arm-soc.git randconfig/pxa

but I haven't added it to the for-next branch for now.

	Arnd

[PATCH 01/26] usb/gadget/pxa25x: is_vbus_present is gone

[Arnd Bergmann]

A recent commit obsoleted the is_vbus_present function, so
we must not use it any more.

[PATCH 02/26] sound/pxa-zylonite: use a valid device for dev_err()

[Arnd Bergmann]

A recent conversion has introduced references to &pdev->dev, which does
not actually exist in all the contexts it's used in.

Replace this with card->dev where necessary, in order to let
the driver build again.

[PATCH 03/26] scsi/mvsas: use proper namespace for IRQ_* symbols

[Arnd Bergmann]

The identifiers in the mvsas driver conflict with platform specific
interrupt definitions of the same name, so better prefix them
with MVS_ to avoid the collision.

[PATCH 05/26] ARM: pxa: make zylonite_pxa*_init declaration match code

[Arnd Bergmann]

When support for zylonite is disabled, the zylonite_pxa300_init
and zylonite_pxa320_init functions are not there, but the declaration
is still kept around if any other boards for the same soc are
enabled. This changes the declaration to be conditional on the
same symbol as the code.

[PATCH 07/26] ARM: pxa: mbxfb: disable broken debugfs code

[Arnd Bergmann]

This code has not worked for a long time, and even the
Makefile entry for building the file was misspelled.
Mark it as broken.

[PATCH 08/26] ARM: pxa: move z2 to generic cpu_suspend

[Arnd Bergmann]

The cpu_suspend code on pxa has recently changed, and the
z2 board did not get updated yet. This makes it do the
same as the other boards.

[PATCH 10/26] ARM: pxa: allow selecting just one of TREO680/CENTRO

[Arnd Bergmann]

There are two variants of the palmtreo machine, the 680 and the
centro, and Kconfig allows selecting one or both of them.
This changes the board file so that it's actually possible
to build all configurations that are allowed.

[PATCH 11/26] ARM: pxa: allow building palm27x without pxafb

[Arnd Bergmann]

The frame buffer device is defined conditionally on whether the
driver is configured. However, the #ifdef guard around the
declaration of palm27x_lcd_init also removes the visibility
of the lcd mode declarations, which need to be available in
order to build correctly, even if they are not defined in the
end.

[PATCH 13/26] ARM: pxa: use correct __iomem annotations

[Arnd Bergmann]

This tries to clear up the confusion between integers and iomem pointers
in the marvell pxa platform. MMIO addresses are supposed to be __iomem*
values, in order to let the Linux type checking work correctly. This
patch moves the cast to __iomem as far back as possible, to the place
where the MMIO virtual address windows are defined.

[PATCH 14/26] mtd: nand_h1900 never worked

[Arnd Bergmann]

This driver has been broken through all of git history and
cannot even be built. Better mark it as broken. Next stop is
removing from the tree.

This driver can only be built for pxa25x and pxa27x at the moment,

[PATCH 17/26] ARM: pxa: pxa95x is incompatible with earlier pxa

[Arnd Bergmann]

We cannot support ARMv5 and ARMv7 based boards in a single kernel,
so introduce a new option in mach-pxa to select between the two.

The PJ4 (ARMv7) based boards are now only visible when
CONFIG_ARCH_PXA_V7 is set, the other boards are only visible
when it's not set.

This hides the option if CPU_PJ4 is enabled, but it will only be set
to 'y' if PXA27x || PXA3xx || PXA95x || ARCH_MMP are set.  Luckily,
ARCH_MMP will be - but is that really what's intended?  It's a little
obscure to work that out.

It was the idea at least, but you are right: adding an explicit || CPU_PJ4
to the default makes it more robust and more obvious to the reader.

I've replaced this patch with the version below and pushed the result to

Oh, and please do try to use subject lines which match up with the rest
of the code you're patching - in this case it even looks like whatever
you're using to autogenerate is misfiring as you've got a combination of
- and / in filenames.

The series is about trivial build fixes that are specific to pxa.
I was expecting most of them to go through the pxa tree because
I figured out would be easier to keep them together like this.

I also have a few sound/soc fixes in the respective samsung and
omap series, so if you prefer I can move them to a sound/soc
series and submit them all at once to you instead.

The subject line was hand-written, any problem in there is purely
my own. What is the naming you want for sound/soc, should I use
"ASoC: pxa-zylonite:" or "sound/soc/pxa/zylonite:" or something
else?

Please do.  It's probably not so important at this point in the release
cycle but we've got a tendency to run into cross tree issues with ASoC
and when it's not trivial build stuff I'd rather review anyway.

Please split the OMAP stuff out, Liam manages the tree for those when
he's available (though right now he's only intermittently online so I'm
applying those too).

Almost all the patches I have are both trivial and unimportant corner
cases. I'm removing the ones I have from all the other branches now
and will try to get them to you both asap.

I think this is true for other xscale CPUs as well, so either we make
them unconditionally all at once, or we still leave an option here.

It actually looks quite odd to me that CPU_PJ4 is made special here,
what're the real broken builds errors?

[PATCH 16/26] ARM: pxa: CPU_PJ4 requires IWMMXT

[Arnd Bergmann]

Do all xscale have iwmmxt?

Yes.

I should probably have provided a longer description of the problem.
The build error is in arch/arm/kernel/pj4-cp0.c, which calls
iwmmxt_task_release unconditionally. The code is obviously
copy-pasted from arch/arm/kernel/xscale-cp0.c, which does much
of the same, but uses both run-time and compile-time conditionals
for iwmmxt.

It's actually __irq_entry being defined in <linux/ftrace.h> and in turn
__exception_irq_entry being conditionally defined to that.

I think it's better to fix this in <asm/system.h> instead of in the
cases where this macro is referenced?

PXA95x is actually PJ4 based, which is ARMv7/v6 compatible, not
like it's predecessor PXA93x. Although they are currently sharing
some code, I expect a fork in the near future. To cause less confusion
here, I'd propose to further introduce pxa95x.h, and to remove
the unnecessary #include of <mach/mfp.h> and <mach/mfp-pxa930.h>

To be honest, I'd really like to keep the *_VIRT_BASE definitions to be
type independent.

And have the actual register definitions to be casted to void __iomem *
when being defined, e.g.

#define APBC_REG(x)	IOMEM(APBC_VIRT_BASE + (x))

#define APBC_UART1	APBC_REG(0x000)

Arnd, do we have some standard guidelines on this for all SoCs
to follow? As I know, it's currently still being a mess.

It makes much more sense for the base address to be correctly typed (even
though it does mean a cast in the map_desc tables).  It avoids type
problems if someone does readl(APBC_VIRT_BASE + reg) somewhere, and
also avoids type problems should someone decide to pass the base address
around.

You really shouldn't have an extern declaration in a .c file. Otherwise
looks good to me.

We don't have any formal guidelines yet, but I'd really love to get
rid of all the arbitrary type casts to make use of the built-in
type checking of the compiler and sparse. A virtual base address
for registers is conventionally an __iomem pointer, so defining it
as something else is completely bogus. I have started making patches
for a number of platforms for this.

Ideally we should have very little code directly using, but the fact
is that they are there and we won't remove them all anytime soon, so
we should at least use the correct types here.

Another issue that goes together with this is that right now our
readl/writel macros accept any input type (pointer, __iomem pointer,
unsigned long, unsigned int), and I have a patch to make that stricter
but that requires fixing up all the places where we do a
readl(APBC_VIRT_BASE + x) that Russell mentioned.

The only place where this requires adding extra type casts right now is
the iotable setup, which I hope we can also fix eventually by splitting
the static I/O mapping setup from other static mappings (MT_MEMORY,
MT_MEMORY_NONCACHED, ...).

Could we avoid to use PXA_V7_MACH_AUTO? I think the better way is
defining a new ARCH (ARCH_PXA95X or something else), and sharing the
code in arch/arm/mach-pxa. I think that it's easy to implement.

How about you, Russell & Eric?

Haojian,

The patch here is to fix the issue of V5 boards and V7 boards being
built together yet it's not supported (there will be building errors).
And this could be easily spotted with auto/random configurations.

I generally think the patch is fine before we'll allow building of both
v5 and v7 code together (which Nico will be definitely interested in)

Eric,

At first, a new macro (ARCH_PXA_V7) is defined in
arch/arm/mach-pxa/Kconfig in this patch.
I prefer to move this macro to arch/arm/Kconfig.

Secondly, pxa95x is both used in saarb and tavorevb3.

Thirdly, PXA_V7_MACH_AUTO is unnecessary. We just need to select those
machines in defconfig or define a new DT machine type to select all
machines.

Thanks

It is actually fixable, the problem is really mtd-xip.h is referencing
the interrupt registers directly which I moved them to mach-pxa/irq.c
for better modularization.

I'm fine to drop XIP. I'm afraid Nico's gonna be a bit disappointed
as I broke his favorite XIP code :-)

There's a patch in the patch system which fixes this (7115/3) but I
can't apply it because it doesn't apply to anything in my for-next
tree (it applies to the obsolete 'devel' branch which is rather old
now.)

Hi Arnd,

The option really matters is FB_PXA_SMARTPANEL, which adds support
for the display driver to control an external "smart" LCD panel. And how
about the patch below to fix this - as normal, make empty functions
when not enabled?

A better way might be for the raumfeld board file to compile the code
based on whether POWER_SUPPLY is selected. However, the power supply
code for raumfeld is a bit difficult to separate indeed, let's merge this
before that happens.

Or let's just remove this 'select SMC91X' completely as it's not
strictly required?

BTW - how's the Kconfig cleanup works going? I guess going forward,
the best way for such cases might be to introduce HAVE_SMC91X, and
let SMC91X to depend on this? However, that could in turn introduce
a massive number of HAVE_* for various drivers.

OK, I wasn't aware that devel was obsolete (though I guess if I'd paid 
closer attention to the commit dates I'd have suspected something).

Anyhow, new patch in the tracker as 7115/4 rebased onto for-next.

Yes, looks good as far as I can tell (I still don't quite understand how the
cpu power management all fits together, but I don't see anything wrong with
it either.

If we move it to arch/arm/Kconfig, I would prefer making it a global option,
not a pxa specific one. If we introduce a top-level CONFIG_CPU_V6PLUS
option, we can make a number of decisions inside of Kconfig depend on that,
especially as we move to allow building multiple v6/v7 platforms together,
or multiple v5 platforms for that matter. I believe we don't need to
worry about v5+v7 at this point and can instead assume that won't ever
happen.

The patch makes that very explicit, doesn't it?

Enabling them in defconfig will not help here, it still allows creating
an invalid configuration by disabling both saarb and tavorevb3.
I agree that it would be best to have a single DT machine type that can
handle both saarb and tavorevb3 as well as any future pxa95x based machines,
but nobody has implemented that yet. In the meantime, I think we should
have the PXA_V7_MACH_AUTO or an equivalent mechanism to enforce that at
least one of the two board files gets built into any kernel. This is mostly
important to help the 'make randconfig' builds succeed, not for actual
users getting it wrong accidentally.

Well, I don't care much myself.  I have no use for that capability, even 
though this was interesting to implement.  So it only depends if someone 
relies on this or not.

A few months ago I asked on the list if XIP was still useful, and Tim 
Bird replied that Sony was indeed using it.  So if this is not too hard 
to keep this feature alive then I'd go with that option.

Nobody is using PJ4 as v6 architecture now. CPUv6 is used in old stepping
of Dove and MMP2. CPU_PJ4 only enables CPU_v7 in the mainline code.

If we used ARCH_PXA_V7 in arch/arm/Kconfig, we would have two ARCH for
pxa. One is ARCH_PXA, and the other is ARCH_PXA_V7. Those v5 machine
should be based on ARCH_PXA. And the saarb, tavorevb3 should be based
on ARCH_PXA_V7. So we can avoid to define PXA_V7_MACH_AUTO. I think
the logic of Kconfig could be easier.

Please check this. In your patch, SAARB and TAVOREVB3 is a mutex.

Exactly we need to define a single DT machine type in both arch-pxa
and arch-mmp.
I'll register it first.

Haojian,

PXA_V7_MACH_AUTO is to by default auto enable tavorevb3 when
ARCH_PXA_V7 is selected.

They are actually not mutually exclusive - it's a trick we use to select
MACH_TAVOREVB3 by default but this option also disappears once SAARB
is selected.

Arnd,

The 'depends on ARCH_PXA_V7' could actually be removed here, as the
option is already encapsulated in if ARCH_PXA_V7 ... endif. And this
trick won't work very well when there are more than 2 boards.

Haojian, it's not being deselected, it's just when user selects SAARB,
this config PXA_V7_MACH_AUTO becomes invalid (which means at
least one PXA_V7_MACH is selected), and then you could select
TAVOREVB3 as well.

Just go ahead and apply the patch, make menuconfig and see how
the trick works :-)

Right. It's a bit hard to read when there are only two of them, but that
is the idea.

Actually, the option is outside of the if ARCH_PXA_V7, but that could
easily be changed.

The trick works with as many boards as you like, it just gets a
little clumsy after while, as in

config MACH_OMAP_AUTO_BOARD
        def_bool y
        depends on !MACH_OMAP2_TUSB6010

        select MACH_OMAP_GENERIC if ARCH_OMAP2

          The kernel needs to have support for at least one board
          in order to build. If none is selected, default to the
          generic board.

We should probably do something like this for the ARMv5 based PXA boards,
but at least a randconfig won't trigger that normally, just because there
are so many of them that almost always at least one is enabled. However,
an allnoconfig will fail with PXA right now.

I was referring to building different subarchitectures together.
We want to eventually be able to build a single kernel that
works on e.g. pxa95x (ARMv7) and omap2 (ARMv6), and we hope to get
there within the next few release. This is completely unrelated to
building a combination of old-world (ARMv3/v4/v5) and new-world
(ARMv6/v7) in a single kernel, which is something that we decided
not to try supporting in the forseeable future.

Pushed to l2-mtd-2.6.git, thanks!

NB: I'd just killed it instead...
