Robert Jarzmik 72b195cb71 ARM: pxa: add the number of DMA requestor lines
Declare the number of DMA requestor lines per platform :
 - for pxa25x: 40 requestor lines
 - for pxa27x: 75 requestor lines
 - for pxa3xx: 100 requestor lines

This information will be used to activate the DMA flow control or not.

Arnd Bergmann 343c1cdbc8 ARM: pxa: fix building without IWMMXT
When CONFIG_IWMMXT, the pxa3xx and pxa27x suspend/resume code
emits some xscale specific instructions, which are rejected
by the assembler, because gcc is built with -march=armv5
-mtune=xscale and passes that option to the assembler:

/tmp/cciHumzr.s:553: Error: selected processor does not support ARM mode `mra r2,r3,acc0'
/tmp/cciHumzr.s:605: Error: selected processor does not support ARM mode `mar acc0,r2,r3'
make[3]: *** [arch/arm/mach-pxa/pxa3xx.o] Error 1
/tmp/cci5MUNu.s:326: Error: selected processor does not support ARM mode `mra r2,r3,acc0'
/tmp/cci5MUNu.s:367: Error: selected processor does not support ARM mode `mar acc0,r2,r3'
make[3]: *** [arch/arm/mach-pxa/pxa27x.o] Error 1

Overriding with -Wa,-march=xscale no longer works, so instead
I'm adding an explict ".arch_extension" directive in all four inline
assembly statements, which should work even if they end up in a different
order in the assembly output.

Arnd Bergmann a9a54caed9 ARM: pxa: move extern declarations to pm.h
When CONFIG_IWMMXT is disabled, we get a warning in pxa3xx.c:

arch/arm/mach-pxa/pxa3xx.c: In function 'pxa3xx_cpu_pm_suspend':
arch/arm/mach-pxa/pxa3xx.c:109:2: error: ISO C90 forbids mixed declarations and code [-Werror=declaration-after-statement]

It turns out that there is an 'extern' declaration in the
middle of a function.

For consistency, this moves the declaration and two others from
the same file into pm.h.

Robert Jarzmik adf3442cc8 ARM: pxa: fix DFI bus lockups on startup
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.

Rob Herring 3cdf4ad963 rtc: pxa: convert to use shared sa1100 functions
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.

Rob Herring e8d36d5dbb ARM: kill off set_irq_flags usage
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.

Robert Jarzmik 4be0856fa3 ARM: pxa: transition to dmaengine phase 1
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
code.

Daniel Mack 0da0e22747 ARM: pxa3xx: provide specific platform_devices for all ssp ports
Currently, devices for SSP ports 1, 2 and 3 are registered as compatible
devices to pxa27x-ssp. While the actual IP core is comparable, there are
some subtle differences which users of the SSP ports address by looking at
the 'type' field.

By registering devices of type 'pxa27x-ssp', this 'type' field is
incorrectly set to PXA27x_SSP which confuses the users.

To fix this, provide specific ssp port plaform devices which use
'pxa3xx-ssp' as driver name, an instantiate them from pxa3xx.c.

Properly register on-chip interrupt using the irqdomain logic. The
number of interrupts is taken from the devicetree node. That includes
the following changes:

- cpu_has_ipr() was converted from an inline function to a static bool
variable, so it can be set using the "marvell,intc-priority" property
inside the device node of the tree.

- IRQ_BASE was converted from a macro to a runtime variable so that it
can be initialized dynamically from the DT init code.

- irq_base() now uses pxa_irq_base and just adds an offset.

Hence, there are now no compile-time fixed values used in case of DT
initialization.

Arnd Bergmann 97b09da4ee ARM: pxa: use correct __iomem annotations
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.

Russell King 29cb3cd208 ARM: pm: allow suspend finisher to return error codes
There are SoCs where attempting to enter a low power state is ignored,
and the CPU continues executing instructions with all state preserved.
It is over-complex at that point to disable the MMU just to call the
resume path.

Instead, allow the suspend finisher to return error codes to abort
suspend in this circumstance, where the cpu_suspend internals will then
unwind the saved state on the stack.  Also omit the tlb flush as no
changes to the page tables will have happened.

Rafael J. Wysocki 2eaa03b5be ARM / PXA: Use struct syscore_ops for "core" power management
Replace sysdev classes and struct sys_device objects used for "core"
power management by the PXA platform code with struct syscore_ops
objects that are simpler.

This reduces the code size and the kernel memory footprint.  It also
is necessary for removing sysdevs entirely from the kernel in the
future.

Sebastian Andrzej Siewior b459396ee9 ARM: pxa2xx: reorganize I2C files
This patch moves the platform data definition from
arch/arm/plat-pxa/include/plat/i2c.h to include/linux/i2c/pxa-i2c.h so
it can be accessed from x86 the same way as on ARM.

This change should make no functional change to the PXA code. The move
is verified by building the following defconfigs:
  cm_x2xx_defconfig corgi_defconfig em_x270_defconfig ezx_defconfig
  imote2_defconfig pxa3xx_defconfig spitz_defconfig zeus_defconfig
