Similar to omap1, some of the omap2+ dma channel definitions are
used by some drivers. For moving omap2+ dma channel definitions
to mach-omap2/, the used ones should be defined locally to driver.
Drivers can eliminate it using DT, platform data, or IORESOURCE_DMA

Pull ARM OMAP serial updates from Russell King:
"This series is a major reworking of the OMAP serial driver code fixing
various bugs in the hardware-assisted flow control, extending up into
serial_core for a couple of issues. These fixes have been done as a
set of progressive changes and transformations in the hope that no new
bugs will be introduced by this series.
The problems are many-fold, from the driver not being informed about
updated settings, to the driver not knowing what the intentions of the
upper layers are.
The first four patches tackle the serial_core layer, allowing it to
provide the necessary information to drivers, and the remaining
patches allow the OMAP serial driver to take advantage of this.
This brings hardware assisted RTS/CTS and XON/OFF flow control into a
useful state.
These patches have been in linux-next for most of the last cycle;
indeed they predate the previous merge window. They've also been
posted to the OMAP people."

struct uart_omap_port and struct uart_omap_dma, and associated

in an include file under arch/arm. Move them into the driver itself.

Contained in here is a bunch more reworks of the tty port layer from
Jiri and bugfixes from Alan, along with a number of other tty and

Fixed up some trivial conflicts in the staging tree, due to the fwserial
driver having come in both ways (but fixed up a bit in the serial tree),
and the ioctl handling in the dgrp driver having been done slightly
differently (staging tree got that one right, and removed both
TIOCGSOFTCAR and TIOCSSOFTCAR).

"MMC highlights for 3.8:
Core:
- Expose access to the eMMC RPMB ("Replay Protected Memory Block")
area by extending the existing mmc_block ioctl.
- Add SDIO powered-suspend DT properties to the core MMC DT binding.
- Add no-1-8-v DT flag for boards where the SD controller reports
that it supports 1.8V but the board itself has no way to switch to
1.8V.
- More work on switching to 1.8V UHS support using a vqmmc regulator.
- Fix up a case where the slot-gpio helper may fail to reset the host
controller properly if a card was removed during a transfer.
- Fix several cases where a broken device could cause an infinite
loop while we wait for a register to update.

HSMMC IP on AM33xx need a special setting to handle High-speed cards.
Other platforms like TI81xx, OMAP4 may need this as-well. This depends
on the HSMMC IP timing closure done for the high speed cards.
From AM335x TRM (SPRUH73F - 18.3.12 Output Signals Generation):
The MMC/SD/SDIO output signals can be driven on either falling edge or
rising edge depending on the SD_HCTL[2] HSPE bit. This feature allows
to reach better timing performance, and thus to increase data transfer
frequency.
There are few pre-requisites for enabling the HSPE bit
- Controller should support High-Speed-Enable Bit and
- Controller should not be using DDR Mode and
- Controller should advertise that it supports High Speed in
capabilities register and
- MMC/SD clock coming out of controller > 25MHz

during init
Add HWMOD_EXT_OPT_MAIN_CLK flag to indicate that this IP block is
dependent on an off-chip functional clock that is not guaranteed to be
present during initialization. IP blocks marked with this flag are
left in the INITIALIZED state during kernel init.
This is a workaround for a hardware problem. It should be possible to
guarantee that at least one clock source will be present and active
for any IP block's main functional clock. This ensures that the hwmod
code can enable and reset the IP block. Resetting the IP block during
kernel init prevents any bogus bootloader, ROM code, or previous OS
configuration from affecting the kernel. Hopefully a clock
multiplexer can be added on future SoCs.
N.B., at some point in the future, it should be possible to query the
clock framework for this type of information. Then this flag should
no longer be needed.

This reverts commit 957ee7270d632245b43f6feb0e70d9a5e9ea6cf6
(serial: omap: fix software flow control).
As Russell has pointed out, that commit isn't fixing
Software Flow Control at all, and it actually makes
it even more broken.
It was agreed to revert this commit and use Russell's
latest UART patches instead.

Pull late ARM soc platform updates from Olof Johansson:
"This branch contains updates to OMAP and Marvell platforms (kirkwood,
dove, mvebu) that came in after we had done the big multiplatform
merges, so they were kept separate from the rest, and not separated
into the traditional topics of cleanup/driver/platform features.
For OMAP, the updates are:
- Runtime PM conversions for the GPMC and RNG IP blocks
- Preparation patches for the OMAP common clock framework conversion
- clkdev alias additions required by other drivers
- Performance Monitoring Unit (PMU) support for OMAP2, 3, and
non-4430 OMAP4
- OMAP hwmod code and data improvements
- Preparation patches for the IOMMU runtime PM conversion
- Preparation patches for OMAP4 full-chip retention support
For Kirkwood/Dove/mvebu:
- New driver for "address decoder controller" for mvebu, which is a
piece of hardware that configures addressable devices and
peripherals. First user is the boot rom aperture on armada XP
since it is needed for SMP support.
- New device tree bindings for peripherals such as gpio-fan, iconnect
nand, mv_cesa and the above address decoder controller.
- Some defconfig updates, mostly to enable new DT boards and a few
drivers.
- New drivers using the pincontrol subsystem for dove, kirkwood and
mvebu
- New clean gpio driver for mvebu"

Some instances of the DMTIMER peripheral on OMAP devices have the ability
to interrupt the on-chip DSP in addition to the ARM CPU. Add a DMTIMER
attribute to indicate which timers can interrupt the DSP. By using the
omap_dm_timer_request_by_cap() API, driver will now be able to allocate
a DMTIMER that can interrupt the DSP based upon this attribute and not require
the driver to know which instance has this capability.
DMTIMERs that have the ability to interrupt the DSP on OMAP devices are as
follows ...
- OMAP1 (OMAP5912/16xx/17xx) devices - All 8 DMTIMERs
- OMAP2/3/4 devices - DMTIMERs 5-8
Please note that for OMAP3+, timer8 has the ability to interrupt the DSP and
generate a PWM output.

status
On OMAP4 most modules/hwmods support module level context status. On
OMAP3 and earlier, we relied on the power domain level context status.
Identify all modules that don't support 'context_offs' by adding a
flag bit, HWMOD_OMAP4_NO_CONTEXT_LOSS_BIT. Rest have a valid
'context_offs' populated in .prcm structure already.

Currently hwmod only provides the offset for the context lose
register, and if we attempt to share the same register between two or
more hwmods, the resulting context loss counts get wrong. Thus, we
need a way to specify which bits are used for the context loss
information for each. This is accomplished by adding a new field to
the omap4 prcm struct, 'lostcontext_mask', which specifies a bit-mask
to use for filtering the register.
Mark the affected hwmods appropriately. 'l4_abe' hwmod uses the
LOSTMEM_AESSMEM bit of RM_ABE_AESS_CONTEXT register, as l4_abe doesn't
have its own dedicated register for this purpose. This register is
shared with 'aess' hwmod, thus both hwmods must also specify which
bits of the register are used for them.
This patch only adds the hwmod data, but a future patch should add
code support such that only the specified bits are read and cleared by
the context lose counter update code. If a hwmod doesn't specify
'lostcontext_mask' (default behavior), the whole contents of the
context register should be used without any filtering.

While we move to Common Clk Framework (CCF), direct deferencing of struct

While here also concatenate some strings split across multiple lines

Pull MFD changes from Samuel Ortiz:
"MFD bits for the 3.7 merge window.
As usual we have a few new drivers:
- TI LP8788
- TI OMAP USB TLL
- Maxim MAX8907
- SMSC ECE1099
- Dialog Semiconductor DA9055
- A simpler syscon driver that allow us to get rid of the anatop one.
Drivers are also gradually getting Device Tree and IRQ domain support.
The following drivers got DT support:
- palmas, 88pm860x, tc3589x and twl4030-audio
And those ones now use the IRQ domain APIs:
- 88pm860x, tc3589x, db8500_prcmu
Also some other interesting changes:
- Intel's ICH LPC now supports Lynx Point
- TI's twl4030-audio added a GPO child
- tps6527 enabled its backlight subdevice
- The twl6030 pwm driver moved to the new PWM subsystem
And finally a bunch of cleanup and casual fixes for mc13xxx, 88pm860x,
palmas, ab8500, wm8994, wm5110, max8907 and the tps65xxx family."
Fix up various annoying conflicts: the DT and IRQ domain support came in
twice and was already in 3.6. And then it was apparently rebased.

With the new devices (like, AM33XX and OMAP5) we now only support
DT boot mode of operation and now it is the time to start killing
slowly the dependency on hwmod, so with this patch, we are starting
with device resources.
The idea here is implemented considering to both boot modes -
- DT boot mode
OF framework will construct the resource structure (currently
does for MEM & IRQ resource) and we should respect/use these
resources, killing hwmod dependency.
If pdev->num_resources > 0, we assume that MEM & IRQ resources
have been allocated by OF layer already (through DTB).
Once DMA resource is available from OF layer, we should
kill filling any resources from hwmod.
- Non-DT boot mode
Here, pdev->num_resources = 0, and we should get all the
resources from hwmod (following existing steps)

Pull ARM soc-specific updates from Olof Johansson:
"Most notable here is probably the addition of basic support for the
BCM2835, an SoC used in some of the Roku 2 players as well as the
much-hyped Raspberry Pi, cleaned up and contributed by Stephen Warren.
It's still early days on mainline support, with just the basics
working. But it has to start somewhere!
Beyond that there's some conversions of clock infrastructure on tegra
to common clock, misc updates for several other platforms, and OMAP
now has its own bus (under drivers/bus) to manage its devices through.
This branch adds two new directories outside of arch/arm:
drivers/irqchip for new irq controllers, and drivers/bus for the above
OMAP bus. It's expected that some of the other platforms will migrate
parts of their platforms to those directories over time as well."

This patch adds HWMOD data for all the peripherals of
AM335X device and also hooks up to the existing OMAP framework.
hwmod data has been already been cleaned up for the recent
changes in clocktree, where all leaf nodes have been removed,
since with modulemode based control, both clock and hwmod
interface does same thing. This reduces the code size to large
extent and also avoids duplication of same control.
So instead of specifying module's leaf node as a main_clk,
now we are relying on parent clock of module's functional clock.
