Bindings for Samsung S2M and S5M family PMICs are in mess. They are
spread over different files and subdirectories in a non-consistent way.
The devices and respective drivers for them share a lot in common so
everything could be organized in a more readable way.
Reorganize the S2MPS11/13/14/15 Device Tree bindings to match the
drivers for this family of devices:
- move mfd/s2mps11.txt to mfd/samsung,sec-core.txt for the main MFD
driver (common for entire family),
- split clock block to clock/samsung,s2mps11.txt,
- split regulator block to regulator/samsung,s2mps11.txt.

This pull includes driver updates from the usual suspects (bfa, arcmsr,
scsi_dh_alua, lpfc, storvsc, cxlflash). The major change is the addition of
the hisi_sas driver, which is an ARM platform device for SAS. The other
change of note is an enormous style transformation to the atp870u driver
(which is our worst written SCSI driver).

Pull libnvdimm updates from Dan Williams:
"The bulk of this has appeared in -next and independently received a
build success notification from the kbuild robot. The 'for-4.5/block-
dax' topic branch was rebased over the weekend to drop the "block
device end-of-life" rework that Al would like to see re-implemented
with a notifier, and to address bug reports against the badblocks
integration.
There is pending feedback against "libnvdimm: Add a poison list and
export badblocks" received last week. Linda identified some localized
fixups that we will handle incrementally.
Summary:
- Media error handling: The 'badblocks' implementation that
originated in md-raid is up-levelled to a generic capability of a
block device. This initial implementation is limited to being
consulted in the pmem block-i/o path. Later, 'badblocks' will be
consulted when creating dax mappings.
- Raw block device dax: For virtualization and other cases that want
large contiguous mappings of persistent memory, add the capability
to dax-mmap a block device directly.
- Increased /dev/mem restrictions: Add an option to treat all
io-memory as IORESOURCE_EXCLUSIVE, i.e. disable /dev/mem access
while a driver is actively using an address range. This behavior
is controlled via the new CONFIG_IO_STRICT_DEVMEM option and can be

option.

Currently in bq27541 driver, the average power register address is
incorrectly set to 0x76, which would result in an error:
bq27xxx-battery 2-0055: error reading average power register 10: -11
According to the bq27541 datasheet, fix this problem by setting
the average power register address to 0x24.

Merge tag 'media/v4.5-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull second batch of media updates from Mauro Carvalho Chehab:
"This is the second part of the media patches. It contains the media
controller next generation patches, with is the result of one year of
discussions and development. It also contains patches to enable media
controller support at the DVB subsystem.
The goal is to improve the media controller to allow proper support
for other types of Video4Linux devices (radio and TV ones) and to
extend the media controller functionality to allow it to be used by
other subsystems like DVB, ALSA and IIO.
In order to use the new functionality, a new ioctl is needed
(MEDIA_IOC_G_TOPOLOGY). As we're still discussing how to pack the
struct fields of this ioctl in order to avoid compat32 issues, I
decided to add a patch at the end of this series commenting out the
new ioctl, in order to postpone the addition of the new ioctl to the
next Kernel version (4.6).
With that, no userspace visible changes should happen at the media
controller API, as the existing ioctls are untouched. Yet, it helps
DVB, ALSA and IIO developers to develop and test the patches adding
media controller support there, as the core will contain all required
internal changes to allow adding support for devices that belong to
those subsystems"

Generic MTD

drivers
* partitioning cleanups, to prepare for better device-tree based partitioning

- This is really long overdue; too many drivers have to do the same silly
boilerplate to allocate and link up two "independent" structs, when in
fact, everyone is assuming there is an exact 1:1 relationship between a
NAND chips struct and its underlying MTD. This aids improved helpers and
should make certain abstractions easier in the future.
- Also causes a lot of churn, helped along by some automated code
transformations

This round we have few new features, new driver and updates to few drivers.
The new features to dmaengine core are:
- Synchronized transfer termination API to terminate the dmaengine
transfers in synchronized and async fashion as required by users.
We have its user now in ALSA dmaengine lib, img, at_xdma, axi_dmac
drivers.
- Universal API for channel request and start consolidation of request
flows. It's user is ompa-dma driver.
- Introduce reuse of descriptors and use in pxa_dma driver
Add/Remove:
- STM32 DMA driver
- Removal of unused R-Car HPB-DMAC driver
Updates:
- ti-dma-crossbar updates for supporting eDMA
- tegra-apb pm updates
- idma64
- mv_xor updates
- ste_dma updates

The code in efi.c uses early_memremap(), but relies on a transitive
include rather than including asm/early_ioremap.h directly, since
this header did not exist on ia64.
Commit f7d9248942 ("arm64/efi: refactor EFI init and runtime code
for reuse by 32-bit ARM") attempted to work around this by including
asm/efi.h, which transitively includes asm/early_ioremap.h on most
architectures. However, since asm/efi.h does not exist on ia64 either,
this is not much of an improvement.
Now that we have created an asm/early_ioremap.h for ia64, we can just
include it directly.

Unlike x86, arm64 and ARM, ia64 does not declare its implementations
of early_ioremap/early_iounmap/early_memremap/early_memunmap in a header
file called <asm/early_ioremap.h>
This complicates the use of these functions in generic code, since the
header cannot be included directly, and we have to rely on transitive
includes, which is fragile.
So create a <asm/early_ioremap.h> for ia64, and move the existing
definitions into it.
