a55b316e02 brcmsmac: remove PCIE() macro
Instead of checking if there is a PCIe core on the bus, better check if
hosttype is PCIe.

In the original submission to staging PCIE() checked, if the bustype is
PCI and the buscore is a PCIe core. Now we assume that all cores bcma
supports are PCIe based, so we just have to check if the bustype is PCI.

The old code bcmsmac currently uses searches for a PCIe core on the bus
and if there is one assumes that this is the buscore, which is wrong.
Some SoCs have a PCIe core operating in host mode and this is not the
bus core. The old code also caused a null pointer in
ai_get_buscoretype() and ai_get_buscorerev() if buscore was not set
because there was no PCIe core on the bus.

7be531883a regulator: tps65910: correct init value of n_voltages
Recent change in the core driver to get the maximum voltage
is based on the (n_voltages -1) steps of voltage.
For the tps65910, the (n_voltages -1)th step voltage is
calculated based on the callback function list_voltage.
This function direct maps the datasheet and adjust the
first few steps for initial voltage as per datasheet,
and hence initialize the n_voltages based on datasheet.

commit 587cc28 ("wlcore: compare ssid_len before comparing

request struct was compared against the ssid length of
another request, instead the one of the cmd.

4455556d71 wlcore: don't set SDIO_FAILED flag when driver state is off
If some IO read/write fails while the FW is not loaded, a recovery
will not take place. This means the SDIO_FAILED flag will stay in place
forever and prevent further read/writes.

This can happen if a check for STATE_OFF was forgotten in some routine.

Take this opportunity to rename the flag to IO_FAILED, since we support
other buses as well.

c45ee4ff1f wlcore: change the wait for event mechanism
wlcore needs to wait for certain events for example
for roc complete event. Usually the events are received
from the FW very fast, therefore wlcore can poll with
a short delay and if after a second the event was
not received yet poll with a long (1-5 msec) delay.

This implementation is similar to the sending of
commands to the FW.

Empirically the change reduced the wait for roc event
from ~10-40msec to 100s of usecs.

c24ec83bca wlcore: Prevent processing of work items during op_stop
The interrupt line is disabled in op_stop using disable_irq. Since
pending interrupts are synchronized, the mutex has to be released before
disabling the interrupt to avoid a deadlock with the interrupt handler.

In addition, the internal state of the driver is only set to 'off'
after the interrupt is disabled. Otherwise, if an interrupt fires after
the state is set but before the interrupt line is disabled, the
interrupt handler will not be able to acknowledge the interrupt
resulting in an interrupt storm.

The driver's operations might be called during recovery. If these
acquire the mutex after it was released by op_stop, but before the
driver's state is changed, they may queue new work items instead of just
failing. This is especially problematic in the case of scans, in which a
new scan may be scheduled after all scan requests were cancelled.

1c97593112 sparc/PCI: replace pci_cfg_fake_ranges() with pci_read_bridge_bases()
The generic code to read P2P bridge windows is functionally equivalent
to the sparc-specific pci_cfg_fake_ranges(), so use the generic code.

The "if (!res->start) res->start = ..." removed from the I/O window code
here was an artifact of the Intel 1K window support from 9d265124d0 and
is no longer necessary (it probably was just cloned from x86 and was never
useful on sparc).

0564414706 spi/gpio: start with CS non-active
The chip select line was configured as output with the initial value
being active explicitly. It was later deasserted during
spi_bitbang_setup() without any clock activity in between. So it makes
no sense to activate the device at all and the chip select line can
better start non-active.

619ac8d3e5 spi: tegra: use dmaengine based dma driver
Use the dmaengine based Tegra APB DMA driver for
data transfer between SPI FIFO and memory in
place of legacy Tegra APB DMA.

The new driver is selected if legacy driver is not
selected and new DMA driver is enabled through config
file.

From Tony Lindgren <tony@atomide.com>:
Here is one PM regression fix and a defconfig change to disable
echi-omap because the driver currently causes issues with PM.
This annoys Kevin as it makes it harder for him to validate that
PM is working. The proper fixes for the echi-omap are being
discussed, but looks like it will not be properly working with PM
until in v3.7.

81ab1f74ef Merge branch 'mvebu/newsoc' into next/newsoc
From: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

You'll find in this patch set the nineth version of the initial
support for a new family of ARMv7-compatible Marvell SoCs.

As for the previous releases, both the Armada 370 and the Armada XP
SoCs are supported in this directory, and we are able to build a
single kernel image that boots on both SoCs. Both SoCs use the PJ4B
processor, a Marvell-developed ARM core that implements the ARMv7
instruction set. We are currently using Marvell evaluation boards for
both of those SoCs, and the support for those boards is added in this
patch set.

This patch set, and the support for those SoCs, started as a
collaborative effort from Marvell engineers (who have done the initial
development work) and Free Electrons engineers (who are reshaping the
code for mainline submission, adding device tree support, etc.). This
effort has also received contributions from Ben Dooks from Codethink.

* mvebu/newsoc:
  ARM: mvebu: MPIC: read number of interrupts from control register
  arm: mach-mvebu: add entry to MAINTAINERS
  arm: mach-mvebu: add compilation/configuration change
  arm: mach-mvebu: add defconfig
  arm: mach-mvebu: add documentation for new device tree bindings
  arm: mach-mvebu: add support for Armada 370 and Armada XP with DT
  arm: mach-mvebu: add source files
  arm: mach-mvebu: add header
  clocksource: time-armada-370-xp: Marvell Armada 370/XP SoC timer driver

Changes from Arnd
* Pulled from git://github.com/Marvell-Semi/EBU_mainline_public.git mvebu_for-next-V9
* rebased onto v3.5-rc5 because it was originally based on
  an old arm-soc/for-next branch
