Pull ARM soc multiplatform enablement from Olof Johansson:
"This is a pretty significant branch. It's the introduction of the
first multiplatform support on ARM, and with this (and the later
branch) merged, it is now possible to build one kernel that contains
support for highbank, vexpress, mvebu, socfpga, and picoxcell. More
platforms will be convered over in the next few releases.Two critical last things had to be done for this to be practical and
possible:
* Today each platform has its own include directory under
mach-/include/mach/*, and traditionally that is where a lot
of driver/platform shared definitions have gone, such as platform
data structures. They now need to move out to a common location
instead, and this branch moves a large number of those out to
include/linux/platform_data.
* Each platform used to list the device trees to compile for its
boards in mach-/Makefile.boot.Both of the above changes will mean that there are some merge
conflicts to come (and some to resolve here). It's a one-time move
and once it settles in, we should be good for quite a while. Sorry
for the overhead."Fix conflicts as per Olof.

As follow-up to "dt: introduce of_get_child_by_name to get child node by
name." patch, This patch removes some of the code duplication in the
driver by replacing it with of_get_child_by_name instead.Signed-off-by: Srinivas Kandagatla
Signed-off-by: Rob Herring -
The current SPI driver has many issues. Examples are:
* Segfaulting on most transfers due to expecting all transfers to have
both RX and TX buffers.
* Hanging on TX transfers since the whole driver flow is driven by RX
DMA completion, but the HW is only told to enable RX for RX transfers.
* Use of clk_disable_unprepare() from atomic context.
* Once those and other minor issues are fixed, the driver still doesn't
actually work.
* The driver also implements a deprecated API to the SPI core.For this reason, simply remove the driver completely. This has two
advantages:1) This will remove the last use of Tegra's , which will
allow that file to be removed, which is required for single zImage
work.2) The downstream driver is significaly different from the current
code. I believe a patch to re-add the downstream driver (with
appropriate cleanup) will be much simpler to review if it's a new
file rather than randomly interspered with essentially unrelated
existing code.Signed-off-by: Stephen Warren

This factors out the resource handling in runtime

with runtime PM in resumed mode, so that ordinary suspend

leading to mixed device tree and platform data. This patch makes it possible to

Amend the PL022 pin controller to optionally take a pin control
handle and set the state of the pins to "default" on boot and
runtime resume, and to "sleep" at runtime suspend. This way we
will dynamically save power on the SPI busses, for example some
electronic designs may be able to ground the pins when unused
instead of pull-up. Some pin controllers may want to set the
pins as wake-up sources when sleeping.Effect on platforms using the PL022 driver:
- If the platform does not use pin control - no semantic effect,
the pinctrl stubs will kick in and resolve the situation.- Platforms using this driver and have pin control but no
function defined for the PL022 need to either supply a
"default" function in their map or enable pinctrl dummies
so the driver is satisfied.- Platforms using this driver with hogs for setting up the PL022
pin control - stop using hogs to take the pl022 pin control
handle, let the driver handle this.I'be looked at some platforms that may be affected:
- SPEAr: appears to define the proper functions in their device
trees and not hogging them, so things should be smooth, the
driver will simply start to take its pins.- Ux500: the proper function is defined and will be taken properly
by the driver. New sleep states introduced by a separate patch to
ux500 but no regression, since the default state is sufficient.- U300: old hog deleted as part of this patch.
- LPC32xx: does not appear to be using pinctrl.
- ARM Integrator IMPD1, RealView & Versatile: does not use pinctrl.

From "Uwe Kleine-König" :
this is the 2nd version of this series whose goal is to make struct
of_device_id.data const. Conceptually a driver must not modify the data
contained there so making it const is the right thing.v1 of this series was sent with Message-id:
1342182734-321-1-git-send-email-y. Changes since then are:
- powerpc fixes
- several new consts that were found by Arnd that are possible after
patch 19.Arnd suggested to take this series via arm-soc late for 3.6 in one go
because patch 19 depends on the former patches but is a precondition to
the latter and it fixes a few warnings. So getting it in via the
respective maintainer trees would need a much bigger coordination
effort. That means I prefer getting Acks over you taking the patch.Vinod Koul already took
dmaengine: at_hdmac: add a few const qualifiers
that is in next-20120723 as 7fd63ccdad72 now. Vinod, I don't follow your
pull requests, but assuming you didn't let it already pull for 3.6 I
suggest you drop it from your queue and I just take your Ack.This series was build tested for arm (all defconfigs) and powerpc (all
defconfigs and an allyesconfig) and grep didn't find more issues. As
before it introduces a warning in drivers/regulator/twl-regulator.c.
This driver does modify its .of_match_table when a device is bound which
doesn't fits the concept of independant devices. Arnd noticed another
new warning in drivers/scsi/qlogicpti.c that isn't that easy to resolve,
because the pointer to (now) const data is passed as first argument to
scsi_host_alloc. To fix that properly struct Scsi_Host.hostt needs to
get a const, too. Alternatively I could introduce a cast removing the
const, but I don't like that.* 'ofdeviceiddata' of git://git.pengutronix.de/git/ukl/linux: (25 commits)

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.Cc: spi-devel-general@lists.sourceforge.net

Currently in omap2_mcspi_txrx_dma the tx and the rx support is
interleaved. Make the rx related code in omap2_mcspi_rx_dma
and the tx related code omap2_mcspi_tx_dma and call the functions.While at it remove the braces in the if statements which has only
one line.
Also fix ["foo * bar" to "foo *bar"] warn for the rx and tx variables.Only a cleanup no functional change.

The new chip select handling via GPIO introduced a pointer computation bug:
(int *) pl022 + sizeof(struct pl022)
doesn't point to the data immediately after the actual struct pl022 (as was
intended) but to a multiple of bytes after it because of the (int *) type.Replacing the kludgy pointer arithmetic with managed memory allocation for the
chip selects.Reported-by: Shiraz Hashim

Rework the mxs_ssp_timeout() function to make it a bit more readable
and hopefully less error prone. Also, have only one successful exit
from the function and one failing exit instead of two.Finally, discard the udelay() from this function altogether, as this
tightloop is quick enough it's pointless.Signed-off-by: Marek Vasut

This driver checks the length of transfer to be made and based
on this information, either chooses to transfer data via DMA or
PIO. Decrement this border further to gain better performace eg.
during SPI flash writes.Empiric measurement shows that this gives extra 3kB/s write speed
with a M25P80 flash clocked at 40MHz.Signed-off-by: Marek Vasut

The transfer function incremented (struct spi_message)->actual_length
unconditionally, even if the transfer failed. Rectify this by incrementing
this only if transfer succeeded.Signed-off-by: Marek Vasut
