The raumfeld.c file contains three similar machine definitions,
each with their own init function. If one or more of them are
disabled, we get compile-time warnings:
arm/mach-pxa/raumfeld.c:1070:123: warning: 'raumfeld_connector_init' defined but not used [-Wunused-function]
arm/mach-pxa/raumfeld.c:1082:123: warning: 'raumfeld_speaker_init' defined but not used [-Wunused-function]
This marks the functions as __maybe_unused to avoid the warnings.

In an old commit, we worked around the duplicate definition of
GPIO24_SSP1_SFRM in cm-x2xx.c, which includes files for both
pxa25x and pxa27x. Apparently the problem has come back and we
now have four additional duplicate symbols that cause warnings:
In file included from /git/arm-soc/arch/arm/mach-pxa/pxa27x.h:7:0,
from /git/arm-soc/arch/arm/mach-pxa/cm-x2xx.c:27:
/git/arm-soc/arch/arm/mach-pxa/mfp-pxa27x.h:21:0: warning: "GPIO86_GPIO" redefined
#define GPIO86_GPIO MFP_CFG_IN(GPIO86, AF0)
This uses the same hack as before and undefines all symbols that
are defined more than once. Fortunately, cm-x2xx does not need
any of these.

Currently, include/media is messy, as it contains both the V4L2 core
headers and some driver-specific headers on the same place. That makes
harder to identify what core headers should be documented and what
headers belong to I2C drivers that are included only by bridge/main
drivers that would require the functions provided by them.
Let's move those i2c specific files to its own subdirectory.
The files to move were produced via the following script:
mkdir include/media/i2c
(cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done)
(cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/*/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done)
for i in include/media/*.h; do n=`basename $i`; (for j in $(git grep -l $n); do dirname $j; done)|sort|uniq|grep -ve '^.$' > list; num=$(wc -l list|cut -d' ' -f1); if [ $num == 1 ]; then if [ "`grep i2c list`" != "" ]; then git mv $i include/media/i2c; fi; fi; done
And the references corrected via this script:
MAIN_DIR="media/"
PREV_DIR="media/"
DIRS="i2c/"
echo "Checking affected files" >&2
for i in $DIRS; do
for j in $(find include/$MAIN_DIR/$i -type f -name '*.h'); do

-3k lines.
Main contents here is:
- A bunch of development/cleanup of a few PXA boards
- Removal of bockw platforms on shmobile, since the platform has now gone
completely multiplatform. Whee!
- move of the 32kHz timer on OMAP to a proper timesource
- Misc cleanup of older OMAP material (incl removal of one board file)
- Switch over to new common PWM lookup support for several platforms
There's also a handful of other cleanups across the tree, but the above are

The z2 machine calls pxa27x_set_pwrmode() in order to power off
the machine, but this function gets discarded early at boot because
it is marked __init, as pointed out by kbuild:
WARNING: vmlinux.o(.text+0x145c4): Section mismatch in reference from the function z2_power_off() to the function .init.text:pxa27x_set_pwrmode()
The function z2_power_off() references
the function __init pxa27x_set_pwrmode().
This is often because z2_power_off lacks a __init
annotation or the annotation of pxa27x_set_pwrmode is wrong.
This removes the __init section modifier to fix rebooting and the
build error.

The OV9640 is not using a standard I2C protocol, but an SCCB variant. Maybe

After the conversion of pxa architecture to common clock framework, the
NAND clock can be disabled on startup if no nand driver claims it.
In this case, it happens that if the bootloader used the NAND and set
the DFI arbitration bit, the next access to a static memory controller
area, such as an ethernet card, the system bus will stall, and the core
will be stalled forever.
Fix this by clearing the DFI arbritration bit in pxa3xx startup. The bit
will be enabled the pxa3xx-nand driver on need anyway. The only left
requirement is that upon pxa3xx-nand removal, the bit should be cleared
before the clock is disabled.

The drivers for the SA1100 and PXA RTCs are now mutually exclusive, so
add the memory resource for the sa1100-rtc device. Since the memory
resource is already present in the pxa_rtc_resources, that makes
sa1100_rtc_resources and pxa_rtc_resources equivalent, so use
pxa_rtc_resources for both devices and remove the duplicate
sa1100_rtc_resources.

Currently, the rtc-sa1100 and rtc-pxa drivers co-exist as rtc-pxa has a
superset of functionality. Having 2 drivers sharing the same memory
resource is not allowed by the driver model if resources are properly
declared. This problem was avoided by not adding memory resources to the
SA1100 RTC driver, but that prevents clean-up of the SA1100 driver.
This commit converts the PXA RTC to use the exported SA1100 RTC
functions. Now the sa1100-rtc and pxa-rtc devices are mutually
exclusive, so we must remove the sa1100-rtc from pxa27x and pxa3xx.

set_irq_flags is ARM specific with custom flags which have genirq
equivalents. Convert drivers to use the genirq interfaces directly, so we
can kill off set_irq_flags. The translation of flags is as follows:
IRQF_VALID -> !IRQ_NOREQUEST
IRQF_PROBE -> !IRQ_NOPROBE
IRQF_NOAUTOEN -> IRQ_NOAUTOEN
For IRQs managed by an irqdomain, the irqdomain core code handles clearing
and setting IRQ_NOREQUEST already, so there is no need to do this in
.map() functions and we can simply remove the set_irq_flags calls. Some
users also modify IRQ_NOPROBE and this has been maintained although it
is not clear that is really needed. There appears to be a great deal of
blind copy and paste of this code.

In order to slowly transition pxa to dmaengine, the legacy code will now
rely on dmaengine to request a channel.
This implies that PXA architecture selects DMADEVICES and PXA_DMA,
which is not pretty. Yet it enables PXA drivers to be ported one by one,
with part of them using dmaengine, and the other part using the legacy

Since dm9000 driver added support for a vcc regulator, platform data
based platforms have their ethernet broken, as the regulator claiming
returns -EPROBE_DEFER and prevents dm9000 loading.
This patch fixes this for all pxa boards using dm9000, by using the
specific regulator_has_full_constraints() function.
This was discovered and tested on the cm-x300 board.

Pull clkdev updates from Russell King:
"This series addresses some breakage in clkdev caused by a previous
patch set from the clk tree which introduced per-user clk structures.
This basically renamed the existing 'struct clk' to 'struct clk_hw',
and introduced a new 'struct clk'.
This change will break anyone using clk_add_alias() with the common
clk code enabled. Thankfully, the intersection of users of
clk_add_alias() and those using the common clk code is practically
zero, but this is something which should be fixed to keep the code
sane.
The problem is that clk_add_alias() does this:
r = clk_get(...);
l = clkdev_alloc(r, ...);
clk_put(...);
which causes the alias to store a pointer to 'r', which has been
freed.
The original patch set tried to work around this problem incorrectly -
at clk_get() time, it tried to convert the struct clk to a struct
clk_hw, and then creating a new struct clk from that. Clearly, if the
original struct clk has been freed, then we have a use-after-free bug.
We have other places in the tree which do something similar, so this
series also addresses those locations too.
This series addresses this problem by converting clkdev to store and
use the clk_hw pointer. This allows clk_get() to only have to create
it's per-user struct clk from the clk_hw. We can also get to the
desired clk_hw at clk_add_alias() or clk lookup creation time, when
the struct clk is "alive".
We also perform some cleanups of the code:
- replacing looped calls to clkdev_add() with clkdev_add_table()
- replacing open-coded lookup allocation (which should have been
using clkdev_alloc()) and subsequent clkdev_add() with
clkdev_create()
- replacing open-coded clk_add_alias() with clk_add_alias()"

Since pxa clocks were ported to the clock framework, an ordering issue
appears between clocks and clocksource initialization. As a consequence,
the pxa timer clock cannot be acquired in pxa_timer, and is disabled by
clock framework because it is "unused".
The ordering issue is that in the kernel boot sequence :
start_kernel()
...
time_init()
-> pxa_timer()
-> here the clocksource is initialized
...
rest_init()
kernel_init()
initcalls
-> here the clocks are initialized
In the current sequence, the clocks are initialized way after pxa_timer,
which cannot acquire the OSTIMER0 clock.
To solve this issue, the clocks initialization is moved to pxa_timer(),
so that clocks are initialized before clocksource for non device-tree.
For device-tree, the standard arm time_init() will take care of the
ordering.

Historically, this support was in arch/arm/mach-pxa/lubbock.c and
arch/arm/mach-pxa/mainstone.c. When gpio-pxa was moved to drivers/pxa,
it became a driver, and its initialization and probing happened at
postcore initcall. The lubbock code used to install the chained lubbock
interrupt handler at init_irq() time.
The consequence of the gpio-pxa change is that the installed chained irq
handler lubbock_irq_handler() was overwritten in pxa_gpio_probe(_dt)(),
removing :
- the handler
- the falling edge detection setting of GPIO0, which revealed the
interrupt request from the lubbock IO board.
As a fix, move the gpio0 chained handler setup to a place where we have
the guarantee that pxa_gpio_probe() was called before, so that lubbock
handler becomes the true IRQ chained handler of GPIO0, demuxing the
lubbock IO board interrupts.
This patch moves all that handling to a mfd driver. It's only purpose
for the time being is the interrupt handling, but in the future it
should encompass all the motherboard CPLDs handling :
- leds
- switches
- hexleds
The same logic applies to mainstone board.

arm: pxa: fixes for v4.0-rc5
There are only 2 fixes, one for the zeus board about the regulator changes,
where a typo prevented the zeus board from having a working can regulator,
and one regression triggered by the interrupts IRQ shift of 16 affecting all
boards.

I recently did a rework of the smc91x driver and did some build-testing
by compiling hundreds of randconfig kernels. Unfortunately, my script
was wrong and did not actually test the configurations that mattered,
so I introduced stupid typos in almost every file I touched.
I fixed my script now, built all configurations that actually matter
and fixed all the typos, this is the result.

Fixes: b70661c708 ("net: smc91x: use run-time configuration on all ARM machines")
Signed-off-by: David S. Miller <davem@davemloft.net>
The smc91x driver traditionally gets configured at compile-time
for whichever hardware it runs on. This no longer works on
ARM as we continue to move to building all-in-one kernels.
Most ARM configurations with this driver already use run-time
configuration through DT or through platform_data, but a
few have not been converted yet.
I've checked all ARM boards that use this driver in their
legacy board files, and converted the ones that were using
compile-time configuration in smc91x.h to behave like the
other ones and provide the interrupt polarity along with
the MMIO configuration (width, stride) at platform device
creation time.
In particular, these combinations were previously selectable
in Kconfig but in fact broken:
- sa1100 assabet plus pleb
- msm combined with any other armv6/v7 platform
- pxa-idp combined with any non-DMA pxa variant
- LogicPD PXA270 combined with any other pxa
- nomadik combined with any other armv4/v5 platform,
e.g. versatile.
None of these seem critical enough to warrant a backport
to stable, but it would be nice to clean this up for good.

I would like the patch to get merged through netdev, after
Robert and/or Linus have verified it on at least some hardware.
There are a few other non-ARM platforms using this driver,
I could do the same patch for those if we want to take
it further.

The commit "ARM: pxa: arbitrarily set first interrupt number" changed
the first pxa interrupt to 16.
As a consequence, device-tree builds got broken, because :
- pxa_mask_irq() and pxa_unmask_irq() are using IRQ_BIT()
- IRQ_BIT(x) calculates the interrupts as : x - PXA_IRQ(0)
Before the commit, the first interrupt shift, PXA_IRQ(0) was 0,
therefore IRQ_BIT(x) was x. After the change, it is necessary that the
same shift of 16 is applied between the virtual interrupt number and the
hardware irq number.
This situation comes from the common irq_chip shared between legacy
platform builds and device-tree builds.
Fix the broken interrupts in DT case by adding this shift in the DT case
too.
As a consequence of the IRQ_BIT() is removed alltogether from interrupts
handling, even in the platform data types of platforms :
- a legacy irq domain is used
- the irq_chip handles hardware interrupts
- the virtual to hardware interrupt conversion is fully handled by irq
domain mechanics

This is a good healthy set of various code removals. Total net delta is 8100
lines removed.
Among the larger cleanups are:
- Removal of old Samsung S3C DMA infrastructure by Arnd
- Removal of the non-DT version of the 'lager' board by Magnus Damm
- General stale code removal on OMAP and Davinci by Rickard Strandqvist
- Removal of non-DT support on am3517 platforms by Tony Lindgren
... plus several other cleanups of various platforms across the board.
