9c4d6e5537 clk: rockchip: add new pll-type for rk3036 and similar socs
The rk3036's pll and clock are different with base on the rk3066(rk3188,
rk3288, rk3368 use it), there are different adjust foctors and control
registers, so these should be independent and separate from the series
of rk3066s.

addc3ba666 clk: bcm: Add BCM63138 clock support
BCM63138 has a simple clocking domain which is primarily the ARMPLL
clocking complex, from which the ARM (CPU), APB and AXI clocks would be
derived from.

Since the ARMPLL controller is entirely compatible with the iProc ARM
PLL, we just initialize it without additional parameters.

329cabcecf clk: qcom: Specify LE device endianness
All these clock controllers are little endian devices, but so far
we've been relying on the regmap mmio bus handling this for us
without explicitly stating that fact. After commit 4a98da2164cf
(regmap-mmio: Use native endianness for read/write, 2015-10-29),
the regmap mmio bus will read/write with the __raw_*() IO
accessors, instead of using the readl/writel() APIs that do
proper byte swapping for little endian devices.

So if we're running on a big endian processor and haven't
specified the endianness explicitly in the regmap config or in
DT, we're going to switch from doing little endian byte swapping
to big endian accesses without byte swapping, leading to some
confusing results. On my apq8074 dragonboard, this causes the
device to fail to boot as we access the clock controller with
big endian IO accesses even though the device is little endian.

Specify the endianness explicitly so that the regmap core
properly byte swaps the accesses for us.

2dd52d7f6f clk: st: avoid uninitialized variable use
quadfs_pll_fs660c32_round_rate prints a few structure members
that are never initialized, and also doesn't print the only one
it cares about. We get a gcc warning about the ones that

clk/st/clkgen-fsyn.c:560:93: warning: 'params.sdiv' may be used uninitialized in this function

a085f877a8 clk: qcom: Move cxo/pxo/xo into dt files
Put these clocks into the dt files instead of registering them
from C code. This provides a few benefits. It allows us to
specify the frequency of these clocks at the board level instead
of hard-coding them in the driver. It allows us to insert an RPM
clock in between the consumers of the crystals and the actual
clock. And finally, it helps us transition the GCC driver to use
RPM clocks when that configuration is enabled.

12b76f3bf3 sound fixes for 4.4-rc1
Here are a collection of small fixes tha have been gathered for
 4.4-rc1.  The only significant changes are those in PCI drivers
 Kconfig, to use "depends on" instead of "select" for CONFIG_ZONE_DMA.
 A reverse select is often more user-friendly, but in this case, it
 makes hard to manage with the conflict with ZONE_DEVICE, so changed in
 such a way for now.

1cfc05cbe2 ARC: cpu_relax() to be compiler barrier even for UP
cpu_relax() on ARC has been barrier only for SMP (and no-op for UP). Per
recent discussions, it is safer to make it a compiler barrier
unconditionally.

a6416f57ce ARC: use ASL assembler mnemonic
ARCompact and ARCv2 only have ASL, while binutils used to support LSL as
a alias mnemonic.

Newer binutils (upstream) don't want to do that so replace it.

541366da6a ARC: [arcompact] Handle bus error from userspace as Interrupt not exception
Bus errors from userspace on ARCompact based cores are handled by core
as a high priority L2 interrupt but current code treated it as interrupt
Handling an interrupt like exception is certainly not going to go unnoticed.
(and it worked so far as we never saw a Bus error from userspace until
IPPK guys tested a DDR controller with ECC error detection etc hence
needed to explicitly trigger/handle such errors)

 - So move mem_service exception handler from common code into ARCv2 code.
 - In ARCompact code, define  mem_service as L2 interrupt handler which
   just drops down to pure kernel mode and goes of to enqueue SIGBUS

63f4f7e8df platform/chrome: Branch for v4.4
Here's the branch of chrome platform changes for v4.4. Some have been queued
 up for the full 4.3 release cycle since I forgot to send them in for that
 round (rebased early on to deal with fixes conflicts).
 
 Most of these enable EC communication stuff -- Pixel 2015 support, enabling
 building for ARM64 platforms, and a few fixes for memory leaks.
 
 There's also a patch in here to allow reading/writing the verified boot
 context, which depends on a sysfs patch acked by Greg.

Sorry for the delay in this patch which was mostly caused by getting the
 merger of the mpt2/mpt3sas driver, which was seen as an essential item of
 maintenance work to do before the drivers diverge too much.  Unfortunately,
 this caused a compile failure (detected by linux-next), which then had to be
 fixed up and incubated.  In addition to the mpt2/3sas rework, there are
 updates from pm80xx, lpfc, bnx2fc, hpsa, ipr, aacraid, megaraid_sas, storvsc
 and ufs plus an assortment of changes including some year 2038 issues, a fix
 for a remove before detach issue in some drivers and a couple of other minor
