This branch contains changes needed to make omap2+
work properly with sparse IRQ. It also removes
dependencies to mach/hardware.h. These help moving
things towards ARM single zImage support.
This branch is based on a commit in tty-next
branch with omap-devel-gpmc-fixed-for-v3.7 and
cleanup-omap-tags-for-v3.7 merged in to keep things
compiling and sort out some merge conflicts.
Conflicts:
arch/arm/mach-omap2/omap4-common.c

There's no need to have these in plat-omap any longer. Note that these
could eventually be made local to mach-omap1 instead of being in mach.
But to do that, at least various driver access using omap7xxx.h registers
needs to be fixed first.

As the plat and mach includes need to disappear for single zImage work,
we need to remove plat/hardware.h.
Do this by splitting plat/hardware.h into omap1 and omap2+ specific files.
The old plat/hardware.h already has omap1 only defines, so it gets moved
to mach/hardware.h for omap1. For omap2+, we use the local soc.h
that for now just includes the related SoC headers to keep this patch more
readable.
Note that the local soc.h still includes plat/cpu.h that can be dealt
with in later patches. Let's also include plat/serial.h from common.h for
all the board-*.c files. This allows making the include files local later
on without patching these files again.
Note that only minimal changes are done in this patch for the
drivers/watchdog/omap_wdt.c driver to keep things compiling. Further
patches are needed to eventually remove cpu_is_omap usage in the drivers.
Also only minimal changes are done to sound/soc/omap/* to remove the
unneeded includes and to define OMAP44XX_MCPDM_L3_BASE locally so there's
no need to include omap44xx.h.
While at it, also sort some of the includes in the standard way.

As the interrupts should only be defined in the platform_data, and
eventually coming from device tree, there's no need to define them
in header files.
Let's remove the hardcoded references to irqs.h and fix up the includes
so we don't rely on headers included in irqs.h. Note that we're
defining OMAP_INTC_START as 0 to the interrupts. This will be needed
when we enable SPARSE_IRQ. For some drivers we need to add
#include <plat/cpu.h> for now until these drivers are fixed to
remove cpu_is_omapxxxx() usage.
While at it, sort som of the includes the standard way, and add
the trailing commas where they are missing in the related data
structures.
Note that for drivers/staging/tidspbridge we just define things
locally.

Remove support for omap2+ as it's no longer needed since
it's using matrix-keypad. This way we can remove depency
to plat and mach headers which is needed for ARM common
zImage support.
Also remove INT_KEYBOARD by using omap_kp->irq.
Note that this patch depends on an earlier patch
"ARM: OMAP: Move gpio.h to include/linux/platform_data".

Note that we also remove the cpu_class_is_omap2() check
in gpio-omap.c as the drivers should not call it as we need to
make it local to arch/arm/mach-omap2 for single zImage support.
While at it, arrange the related includes in the standard way.

into cleanup-sparseirq
Changes for GPMC (General Purpose Memory Controller) that take it
closer for being just a regular device driver.
Remove the ancient omap specific atags that are no longer needed.
At some point we were planning to pass the bootloader information
with custom atags that did not work out too well.
There's no need for these any longer as the kernel has been booting
fine without them for quite some time. And Now we have device tree
support that can be used instead.

Pull DMA-mapping fixes from Marek Szyprowski:
"Another set of fixes for ARM dma-mapping subsystem.
Commit e9da6e9905e6 replaced custom consistent buffer remapping code
with generic vmalloc areas. It however introduced some regressions
caused by limited support for allocations in atomic context. This
series contains fixes for those regressions.
For some subplatforms the default, pre-allocated pool for atomic
allocations turned out to be too small, so a function for setting its
size has been added.
Another set of patches adds support for atomic allocations to
IOMMU-aware DMA-mapping implementation.
The last part of this pull request contains two fixes for Contiguous
Memory Allocator, which relax too strict requirements."

Contiguous Memory Allocator requires each of its regions to be aligned
in such a way that it is possible to change migration type for all
pageblocks holding it and then isolate page of largest possible order from
the buddy allocator (which is MAX_ORDER-1). This patch relaxes alignment
requirements by one order, because MAX_ORDER alignment is not really
needed.

They all define their chassis type as "Other" and therefore are not
categorized as "laptops" by the driver, which tries to perform AUX IRQ
delivery test which fails and causes touchpad not working.

Ensure the hardware is correctly initialized before requesting the
interrupt, otherwise if a key was already touched since power-on the
kernel enters an interrupt loop. To fix this issue we clear pending
interrupt sources. We also have to make sure clk is enabled while
changing the keypad registers.

The end result was that if a PCI device was unbind from
its driver, then binded to xen-pciback, and then back to its
driver we would get:

This fixes it by first saving the PCI configuration space, then

When running 32-bit pvops-dom0 and a driver tries to allocate a coherent
DMA-memory the xen swiotlb-implementation returned memory beyond 4GB.
The underlaying reason is that if the supplied driver passes in a
DMA_BIT_MASK(64) ( hwdev->coherent_dma_mask is set to 0xffffffffffffffff)
our dma_mask will be u64 set to 0xffffffffffffffff even if we set it to
DMA_BIT_MASK(32) previously. Meaning we do not reset the upper bits.
By using the dma_alloc_coherent_mask function - it does the proper casting
and we get 0xfffffffff.
This caused not working sound on a system with 4 GB and a 64-bit
compatible sound-card with sets the DMA-mask to 64bit.
On bare-metal and the forward-ported xen-dom0 patches from OpenSuse a coherent
DMA-memory is always allocated inside the 32-bit address-range by calling
dma_alloc_coherent_mask.
This patch adds the same functionality to xen swiotlb and is a rebase of the
original patch from Ronny Hegewald which never got upstream b/c the
underlaying reason was not understood until now.

This patch fixes the following bug:
http://marc.info/?l=linux-pci&m=134338059022620&w=2
Where lspci does not work properly if a device and the corresponding
parent bridge (such as PCIe port) is suspended. This is because the
device configuration space registers will be not accessible if the
corresponding parent bridge is suspended or the device is put into
D3cold state.
To solve the issue, the bridge/PCIe port connected to the device is
put into active state before read/write configuration space registers.
If the device is in D3cold state, it will be put into active state
too.
To avoid resume/suspend PCIe port for each configuration register
read/write, a small delay is added before the PCIe port to go
suspended.

This patch fixes the following bug:
http://marc.info/?l=linux-pci&m=134329923124234&w=2
The root cause of the bug is as follow.
If a device is not bound with the corresponding driver, the device
runtime PM will be disabled and the device will be put into suspended
state. So that, the bridge/PCIe port connected to it may be put into
suspended and low power state. When do probing for the device later,
because the bridge/PCIe port connected to it is in low power state,
the IO access to device may fail.
To solve the issue, the bridge/PCIe port connected to the device is
put into active state before probing.

This patch fixes the following bug:
http://marc.info/?l=linux-usb&m=134318961120825&w=2
Originally, device lower power states include D1, D2, D3. After that,
D3 is further divided into D3hot and D3cold. To support both scenario
safely, original D3 is mapped to D3cold.
When adding D3cold support, because worry about some device may have
broken D3cold support, D3cold is disabled by default. This disable D3
on original platform too. But some original platform may only have
working D3, but no working D1, D2. The root cause of the above bug is
it too.
To deal with this, this patch enables D3/D3cold by default for most
devices. This restores the original behavior. For some devices that
suspected to have broken D3cold support, such as PCIe port, D3cold is
disabled by default.

After commit 26b88520b80695a6fa5fd95b5d97c03f4daf87e0 ("mmc:
omap_hsmmc: remove private DMA API implementation"), the Nokia N800
here stopped booting:

...
This turned out to be due to memory corruption caused by long-broken
PIO code in drivers/mmc/host/omap.c. (Previously, this driver had
been using DMA; but the above commit caused the MMC driver to fall
back to PIO mode with an unmodified Kconfig.)
The PIO code, added with the rest of the driver in commit
730c9b7e6630f786fcec026fb11d2e6f2c90fdcb ("[MMC] Add OMAP MMC host
driver"), confused bytes with 16-bit words. This bug caused memory
located after the PIO transfer buffer to be corrupted with transfers
larger than 32 bytes. The driver also did not increment the buffer
pointer after the transfer occurred. This bug resulted in data
corruption during any transfer larger than 64 bytes.

For several MoviNAND eMMC parts, there are known issues with secure
erase and secure trim. For these specific MoviNAND devices, we skip
these operations.
Specifically, there is a bug in the eMMC firmware that causes
unrecoverable corruption when the MMC is erased with MMC_CAP_ERASE
enabled.

The documentation for the dw_mmc part says that the low power
mode should normally only be set for MMC and SD memory and should
be turned off for SDIO cards that need interrupts detected.
The best place I could find to do this is when the SDIO interrupt
was first enabled. I rely on the fact that dw_mci_setup_bus()
will be called when it's time to reenable.

Data transfer will be continued until all the bytes are transmitted,
even if data crc error occurs during a multiple-block data transfer.
This means RXDR/TXDR interrupts will occurs until data transfer is
terminated. Early setting of host->sg to NULL prevents going into
xxx_data_pio functions, hence permanent unhandled RXDR/TXDR interrupts
occurs. And checking error interrupt status in the xxx_data_pio functions
is no need because dw_mci_interrupt does do the same. This patch also
removes it.

Datasheet of SYNOPSYS mentions that DTO(Data Transfer Over) interrupt
will be raised even if some error interrupts, however it is actually
found that DTO does not occur. SYNOPSYS has confirmed this issue.
Current implementation defers the call of tasklet_schedule until DTO
when the error interrupts is happened. This patch fixes error handling.

RINTSTS status includes masked interrupts as well as unmasked.
data_status and cmd_status are set by value of RINTSTS in interrupt handler
and tasklet finally uses it to decide whether error is happened or not.
In addition, MINTSTS status is used for setting data_status in PIO.
Masked error interrupt will not be handled and that status can be considered
non-error case.

Even if the datasheet says that the not busy flag has to be used only
for write operations, it's false except for version lesser than v2xx.
Not waiting on the not busy flag for read operations can cause the
controller to hang-up during the initialization of some SD cards
with DMA after the first CMD6 -- the next command is sent too early.

Since commit 30832ab56 ("mmc: sdhci: Always pass clock request value
zero to set_clock host op") was merged, esdhc_set_clock starts hitting
"if (clock == 0)" where ESDHC_SYSTEM_CONTROL has been operated. This
causes SDHCI card-detection function being broken. Fix the regression
by moving "if (clock == 0)" above ESDHC_SYSTEM_CONTROL operation.

Pull GPIO fixes from Linus Walleij:
"These are some GPIO regression fixes for v3.6:
- Erroneous debug message from of_get_named_gpio_flags()
- Make sure the MC9S08DZ60 GPIO driver depend on I2C being compiled
in (not module) or allmodconfig breaks.
- Check return value from irq_alloc_descs() in the Emma Mobile GPIO
driver.
- Assign the owner field for the rdc321x driver so the module won't
be removed if it has active GPIOs."
