[PATCH 00/30] ARM: exynos multiplatform support

[PATCH 00/30] ARM: exynos multiplatform support

[Arnd Bergmann]

Hi everyone,

I have updated my series for multiplatform support of the ARM exynos
platform, based on what is currently queued up in arm-soc.

It would be really nice to still get this merged for 3.10. A lot of
the patches are really trivial, but there are some complex ones
as well.

To all subsystem maintainers: feel free to directly apply the patches
for your subsystem, there should be no dependencies between any of them,
aside from the last patch requiring all of the earlier ones to be applied
first. Getting an Ack is also fine so we can put the patches into arm-soc.

	Arnd

[PATCH 01/30] ARM: exynos: introduce EXYNOS_ATAGS symbol

[Arnd Bergmann]

As a preparation for multiplatform support, this introduces
a new Kconfig symbol to split the ATAGS based EXYNOS platforms
from the DT based ones. Turning off CONFIG_EXYNOS_ATAGS disables
all platforms that are not yet converted to DT, and we can
have code that relies on DT checking for this symbol being
disabled.

[PATCH 02/30] ARM: exynos: prepare for sparse IRQ

[Arnd Bergmann]

When we enable CONFIG_SPARSE_IRQ, we have to set the value of NR_IRQS in
the machine_desc for legacy IRQ domains, and any file referring to the
number of interrupts or a specific number must include the mach/irqs.h
header file explicitly.

[PATCH 03/30] ARM: exynos: move debug-macro.S to include/debug/

[Arnd Bergmann]

The move is necessary to support early debug output on exynos
with multiplatform configurations. This implies also moving the
plat/debug-macro.S file, but we are leaving the remaining users of that
file in place, to avoid adding large numbers of extra configuration
options to Kconfig.debug

[PATCH 04/30] ARM: samsung: move mfc device definition to s5p-dev-mfc.c

[Arnd Bergmann]

For a DT-only build we don't want to compile devs.c, but we do need
the mfc device, which is also referenced by the DT based platforms,
so move it all into one place.

[PATCH 05/30] tty: serial/samsung: prepare for common clock API

[Arnd Bergmann]

With the common clock interface, there is no way to provide the
"clock_source" sysfs attribute for the samsung serial ports. Given that
this file was purely informational and had fixed contents, we have reason
to believe that no user space programs were relying on it.

The sysfs file is not documented in the ABI docs.

[PATCH 06/30] tty: serial/samsung: make register definitions global

[Arnd Bergmann]

The registers for the Samsung S3C serial port are currently defined in
the platform specific arch/arm/plat-samsung/include/plat/regs-serial.h
file, which is not visible to multiplatform capable drivers.

Unfortunately, it is not possible to move the file into a more local
place as we should normally try to, because the same registers
may be used in one of four places:

* In the driver itself
* In platform-independent ARM code for early debug output
* In platform_data definitions
* In the Samsung platform power management code

I have also found no way to logically split out a platform_data
file, other than possibly move everything into
include/linux/platform_data, which also felt wrong. The only
part of this file that makes sense to keep specific to the s3c24xx
platform are the virtual and physical addresses defined here,
which are needed in no other location.

[PATCH 07/30] tty: serial/samsung: fix modular build

[Arnd Bergmann]

There are a few bugs in the samsung serial driver when built as a
loadable module, which makes the console code unavailable, as well as
giving no access to the 'printascii' early debug function. This adds
the appropriate compile time conditionals.

[PATCH 08/30] i2c: s3c2410: make header file local

[Arnd Bergmann]

No other file in the kernel besides i2c-s3c2410.c uses the current
plat/regs-iic.h, so we can simply move the header file to live in the
same directory as the driver, as a preparation to multiplatform builds.

[PATCH 09/30] mmc: sdhci-s3c: remove platform dependencies

[Arnd Bergmann]

plat/regs-sdhci.h is not used anywhere but in the sdhci-s3c
driver, so it can become a local file there and all other
inclusions removed.

plat/sdhci.h is used only to define the platform devices,
and with the exception of the platform_data structure not
needed by the driver, so we can split out the platform_data
definition instead and leave the rest to platform code.

[PATCH 10/30] usb: exynos: do not include plat/usb-phy.h

[Arnd Bergmann]

The definitions have moved to include/linux/usb/samsung-usb-phy.h,
and plat/usb-phy.h is unavailable from drivers in a multiplatform
configuration.

Also fix up the plat/usb-phy.h header file to use the definitions
from the new header instead of providing a separate copy.

[PATCH 11/30] [media] exynos: remove unnecessary header inclusions

[Arnd Bergmann]

In multiplatform configurations, we cannot include headers
provided by only the exynos platform. Fortunately a number
of drivers that include those headers do not actually need
them, so we can just remove the inclusions.

[PATCH 13/30] video/s3c: move platform_data out of arch/arm

[Arnd Bergmann]

The s3c-fb driver requires header files from the samsung platforms
to find its platform_data definition, but this no longer works on
multiplatform kernels, so let's move the data into a new header
file under include/linux/platform_data.

[PATCH 16/30] rtc: s3c: make header file local

[Arnd Bergmann]

Nothing outside of the rtc driver includes plat/regs-rtc.h,
so we can simply move the file into the same directory,
which allows us to build the file as platform-independent
code.

[PATCH 17/30] pwm: samsung: repair the worst MMIO abuses

[Arnd Bergmann]

The Samsung PWM driver uses "magic" pointers that are mapped
at boot time to point its MMIO registers. This fails horribly
with a multiplatform kernel, which can not rely on platform
specific header files to contain the right values, aside from
this being a really bad idea in general.

This changes the driver to at least pass an __iomem token
around in the device structure to dereference that. Fixing
the platform code is much harder, so we'll leave that
until we have a DT binding for pwm-samsung, which may require
other changes in this area. Since we are already touching
every MMIO accessor in this driver, let's also use the
proper readl_relaxed variant rather than __raw_readl.

Tomasz Figa has a set of patches to clean this up in a proper
way, but that might be too late for 3.10.

[PATCH 18/30] ASoC: samsung: move plat/ headers to local directory

[Arnd Bergmann]

The plat/iis.h and plat/ac97.h files in the samsung platform are
only needed by the ASoC drivers, so they can be moved into the
same directory, as one more step towards a multiplatform build.

numbers in device drivers. This changes the idma driver
to use a proper resource, like all other drivers do.

[PATCH 20/30] ASoC: samsung: convert to dmaengine API

[Arnd Bergmann]

In order to build the exynos kernel with CONFIG_ARCH_MULTIPLATFORM,
we must convert all users of the Samsung private DMA interface to
the generic dmaengine API. This version of the patch adds the
generic dmaengine API as an alternative to the existing samsung
specific one. Once all the older platforms provide support for
the common dmaengine interfaces, we can remove the old code.

[PATCH 21/30] ASoC: samsung/i2s: fix module_device_table

[Arnd Bergmann]

The second argument to the module_device_table macro must be the
name of the device id array. In the samsung i2s driver, there
was a small typo, resulting in a build error when building it
as a loadable module.

[PATCH 23/30] clk: exynos: prepare for multiplatform

[Arnd Bergmann]

The new common clock drivers for exynos are using compile
time constants and soc_is_exynos* macros to provide backwards
compatibility for pre-DT systems, which is not possible with
multiplatform kernels. This moves all the necessary
information back into platform code and removes the mach/*
header inclusions.

[PATCH 24/30] clocksource: exynos_mct: remove platform header dependency

[Arnd Bergmann]

For the non-DT case, the mct_init() function requires access
to a couple of platform specific constants, but cannot include
the header files in case we are building for multiplatform.

This changes the interface to the platform so we pass all
the necessary data as arguments to mct_init.

[PATCH 25/30] irqchip: exynos: pass max combiner number to combiner_init

[Arnd Bergmann]

We can find out the number of combined IRQs from the device
tree, but in case of ATAGS boot, the driver currently uses
hardcoded values based on the SoC type. We can't do that
in general for a multiplatform kernel, so let's instead pass
this information from platform code directly in case of
ATAGS boot.

[PATCH 26/30] irqchip: exynos: allocate combiner_data dynamically

[Arnd Bergmann]

The number of combiners on a given SoC is a platform specific
constant, and we cannot encode this number on a multiplatform
kernel since the header file defining it is not available.

Allocating the structure dynamically ends up cleaner anyway
since we keep all the data local.

[PATCH 28/30] irqchip: exynos: pass irq_base from platform

[Arnd Bergmann]

The platform code knows the IRQ base, while the irqchip driver
should really not. This is a littly hacky because we still
hardwire the IRQ base to 160 for the combiner in the DT case,
when we should really use -1. Removing that line will cause
a linear IRQ domain to be use, as we should.

[PATCH 29/30] spi: s3c64xx: move to generic dmaengine API

[Arnd Bergmann]

The spi-s3c64xx uses a Samsung proprietary interface for
talking to the DMA engine, which does not work with
multiplatform kernels.

This version of the patch leaves the old code in place,
behind an #ifdef. This can be removed in the future,
after the s3c64xx platform start supporting the regular
dmaengine interface. An earlier version of this patch was
tested successfully on exynos5250 by Padma Venkat.

The conversion was rather mechanical, since the samsung
interface is just a shallow wrapper around the dmaengine
interface.

[PATCH 30/30] ARM: exynos: enable multiplatform support

[Arnd Bergmann]

This makes it possible to enable the exynos platform as part of a
multiplatform kernel, in addition to keeping the single-platform
exynos support.

The multiplatform variant has a number of limitations at the moment:

* It only supports DT-enabled machines. This is not a problem in
  the long run, as non-DT machines for exynos are going away.
  The main problem here is that the gpio code and the exynos_eint
  irqchip are not multiplatform capable but still required for
  ATAGS based boot.
* The watchdog driver is still missing a conversion.
* sparsemem and memory_holes are currently not supported in
  multiplatform.

There's generic ASoC dmaengine code which should be used instead of open
coding this.  Lars-Peter Clausen and Lee Jones have been working on
making this a totally generic driver, right now it's a library.

Ok, I see. I'll drop this patch from my series then and will let someone
else handle this driver in 3.11. We can probably live without sound support
in 3.10 when running a multiplatform kernel, and it will keep working
for exynos-only kernels without the patch.

Can you have a look at the other three ASoC patches in the series? I think
it would still be useful to merge them.

This doesn't apply against my spi-next, can you please check and resend?

This one should work. Unfortunately I now found during testing that the
s3c24xx sound support has a few build errors at the moment, but this
patch should not add any new ones:

Subject: [PATCH] ASoC: samsung: move plat/ headers to local directory

The plat/regs-iis.h and plat/regs-ac97.h files in the samsung platform
are only needed by the ASoC drivers, so they can be moved into the same
directory, as one more step towards a multiplatform build.

Hrm, someone killed GTA02 support?  That's sad...  if that's really the
case we could kill the machine driver but not tonight as I'm running
late...

[PATCH] ASoC: samsung: fix neo1973-wm8753 compilation

Commit b2ca78717cea (ARM: S3C24XX: make gta02.h local) already replaced
the GTA02_GPIO_* constants in neo1973-wm8753.c but forgot to remove the
inclusion of mach/gta02.h before moving the file out of mach/.

This patch doesn't apply to my usb-next tree due to the other changes in
these files.

Care to refresh it and resend it?  I'll be glad to apply it then.

[PATCH v2] spi: s3c64xx: move to generic dmaengine API

[Arnd Bergmann]

The spi-s3c64xx uses a Samsung proprietary interface for
talking to the DMA engine, which does not work with
multiplatform kernels.

This version of the patch leaves the old code in place,
behind an #ifdef. This can be removed in the future,
after the s3c64xx platform start supporting the regular
dmaengine interface. An earlier version of this patch was
tested successfully on exynos5250 by Padma Venkat.

The conversion was rather mechanical, since the samsung
interface is just a shallow wrapper around the dmaengine
interface.

[PATCH v3] usb: exynos: do not include plat/usb-phy.h

The definitions have moved to include/linux/usb/samsung-usb-phy.h,
and plat/usb-phy.h is unavailable from drivers in a multiplatform

Also fix up the plat/usb-phy.h header file to use the definitions
from the new header instead of providing a separate copy.

Joonyoung Shim (Cc'ed) posted a driver for Exynos back in December. I
had a few comments on it but never saw an updated version. Is Tomasz'
work based on that patch?

Given that this patch solves a real problem and doesn't make things any
worse, I think it's okay to use it temporarily until Tomasz has had time
to finish up the proper driver, so:

Is this the patch you are talking about?

https://lkml.org/lkml/2012/12/13/84

If yes, it solves the problems only for Exynos SoCs (excluding Exynos 4210 
rev0), which don't need to share the PWM hardware between two drivers.

On older platforms (S3C24xx, S3C64xx, S5P64x0, S5PC100, S5PV210 and Exynos 
4210 rev0) the same hardware block is used for two drivers - clocksource 
driver and PWM driver.

You can get more information from these two threads:

- http://thread.gmane.org/gmane.linux.kernel.samsung-soc/16480/focus=16510
(starting from the linked post)

- http://thread.gmane.org/gmane.linux.kernel.samsung-soc/17464
 

> Given that this patch solves a real problem and doesn't make things any
> worse, I think it's okay to use it temporarily until Tomasz has had time
> to finish up the proper driver, so:

Well, from what I've seen, the PWM might have been already broken on non-
DT platforms using channels higher than 0, because the driver registers 
each channel passing -1 as base, which makes the id being assigned 
dynamically (usually to 0, since it's the only PWM channel used), while in 
all platform data, the real (hardware) PWM channel id is used and no PWM 
lookup is registered.

You can use the following grep to find all platforms with broken PWM:
git grep pwm_id arch/arm/mach-s[35]* | grep -v "= 0"

I have a set of patches to fix everything up in the PWM driver, but they 
depend on my patches providing the infrastructure to share the PWM 
hardware, on next version of which I'm currently working.

So, for now, Arnd's patch is fine to me as well.

Best regards,
Tomasz

I think the file was moved, we should pull over the audio relevant GPIO

I actually had a look at how the Samsung PCM driver a couple of days back,
but I didn't fully grasp how things work with the secondary TX channel for
the i2s driver and to make it work with the generic dmaengine PCM driver.
The code handling this in the i2s driver seems to be rather messy with lots
of ifs and elses. Also things would have would be a lot easier if the dt
bindings had used two subnodes each with their own 'dmas' property.

Yeah, it's quite messy at the minute as it predates any subsystem
support for things like multiple DMA channels going into a single DAI on
an AP so it was having to do things it really shouldn't have done.  What
ought to happen is that the driver gets refactored to use soc-pcm or
change to represent the mixer block as a CODEC, I think if that happens
then things ought to get easier.

Actually it seems that this patch is causing issues for bulk SPI
transfers on s3c64xx, especially when they're driven quickly one after
another.  I've only just found the problem so I've not been able to
debug yet but a revert fixes it...

Can you try just reverting this hunk? It's actually not required and
comes from an earlier version of the patch. I assumed it was harmless,
but it's the only think I see that should actually make a difference
in my patch for the case of !CONFIG_SAMSUNG_DMADEV.

That's not it, the checks are now needed - otherwise we get a null
pointer dereference in prepare_dma() instead.  What's actually gone
wrong is that your ifdefs are for SAMSUNG_DMADEV instead of S3C_DMA
so s3c64xx is trying to use dmaengine.  The driver doesn't actually
check to see if it failed to get the channels so it then tries to do the
transfer with a missing channel which unsurprisingly fails.
