Pull clock framework updates from Mike Turquette:
"The clock framework changes for 3.16 are pretty typical: mostly clock
driver additions and fixes. There are additions to the clock core
code for some of the basic types (e.g. the common divider type has
some fixes and featured added to it).
One minor annoyance is a last-minute dependency that wasn't handled
quite right. Commit ba0fae3b06a6 ("clk: berlin: add core clock driver
for BG2/BG2CD") in this pull request depends on
include/dt-bindings/clock/berlin2.h, which is already in your tree via
the arm-soc pull request. Building for the berlin platform will break
when the clk tree is built on it's own, but merged into your master
branch everything should be fine"

The Allwinner sunxi mmc host uses dma in bus-master mode using a built-in
designware idmac controller, which is identical to the one found in the mmc-dw
hosts. However the rest of the host is not identical to mmc-dw, it deals with
sending stop commands in hardware which makes it significantly different
from the mmc-dw devices.

For CONFIG_PM_SLEEP, the device were always left in full power state
after system suspend.
We solely relied on a power domain to put it into low power state,
which is an unreasonable requirement to put on SOCs to implement.
Especially for those SOCs not supporting power domains at all.
Use pm_runtime_force_suspend|resume() as the system suspend callbacks,
to resolve the issue.

In runtime suspended state, we are not expecting IRQs and thus we can

This reverts commit c42deffd5b53c9e583d83c7964854ede2f12410d.
commit <mmc: rtsx: add support for pre_req and post_req> did use
mutex_unlock() in tasklet, but mutex_unlock() can't be used in
tasklet(atomic context). The driver needs to use mutex to avoid
concurrency, so we can't use tasklet here, the patch need to be
removed.
The spinlock host->lock and pcr->lock may deadlock, one way to solve
the deadlock is remove host->lock in sd_isr_done_transfer(), but if
using workqueue the we can avoid using the spinlock and also avoid
the problem.

Pull ARM changes from Russell King:
- Perf updates from Will Deacon:
- Support for Qualcomm Krait processors (run perf on your phone!)
- Support for Cortex-A12 (run perf stat on your FPGA!)
- Support for perf_sample_event_took, allowing us to automatically decrease
the sample rate if we can't handle the PMU interrupts quickly enough
(run perf record on your FPGA!).
- Basic uprobes support from David Long:
This patch series adds basic uprobes support to ARM. It is based on
patches developed earlier by Rabin Vincent. That approach of adding
hooks into the kprobes instruction parsing code was not well received.
This approach separates the ARM instruction parsing code in kprobes out
into a separate set of functions which can be used by both kprobes and
uprobes. Both kprobes and uprobes then provide their own semantic action
tables to process the results of the parsing.
- ARMv7M (microcontroller) updates from Uwe Kleine-König
- OMAP DMA updates (recently added Vinod's Ack even though they've been
sitting in linux-next for a few months) to reduce the reliance of
omap-dma on the code in arch/arm.
- SA11x0 changes from Dmitry Eremin-Solenikov and Alexander Shiyan
- Support for Cortex-A12 CPU
- Align support for ARMv6 with ARMv7 so they can cooperate better in a
single zImage.
- Addition of first AT_HWCAP2 feature bits for ARMv8 crypto support.
- Removal of IRQ_DISABLED from various ARM files
- Improved efficiency of virt_to_page() for single zImage
- Patch from Ulf Hansson to permit runtime PM callbacks to be available for
AMBA devices for suspend/resume as well.

The SDHCI unit used on the Armada 380 and 385 Marvell SoC is similar
to the PXAv3 unit. The only difference is that on Armada 38x, the
PXAv3 unit accesses memory through MBus windows which must be
configured prior to using the device. Without this, DMA would not
work.
In order to achieve this, the sdhci-pxav3 driver is extended with an
additional compatible string "marvell,armada-380-sdhci". When this
compatible string is used, the MBus windows are initialized in a way
that is identical to what all other DMA-capable drivers for Marvell
EBU platforms do.

When the host->tuning_count is zero it means that the retuning is
disabled. This is checked on the first run of sdhci_execute_tuning()
by the if statement below:
if (!(host->flags & SDHCI_NEEDS_RETUNING) && host->tuning_count &&
(host->tuning_mode == SDHCI_TUNING_MODE_1)) {
So only when tuning_count is non-zero it will set the host flag
SDHCI_USING_RETUNING_TIMER. The else statement is only for re-programming
the timer, which means that flag must be set. Because that is not checked
the else statement is executed in the first run when tuning_count is zero.
This was seen on a host controller which indicated SDHCI_TUNING_MODE_1 (0)
and tuning_count being zero. Suspect that (one of) these registers is not
properly set.

sdhci-spear is unsafe should a probe fail or defer, since it overwrites
