git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap
Pull regmap updates from Mark Brown:
"This has been a busy release for regmap.
By far the biggest set of changes here are those from Markus Pargmann
which implement support for block transfers in smbus devices. This
required quite a bit of refactoring but leaves us better able to
handle odd restrictions that controllers may have and with better
performance on smbus.
Other new features include:
- Fix interactions with lockdep for nested regmaps (eg, when a device
using regmap is connected to a bus where the bus controller has a
separate regmap). Lockdep's default class identification is too
crude to work without help.
- Support for must write bitfield operations, useful for operations
which require writing a bit to trigger them from Kuniori Morimoto.
- Support for delaying during register patch application from Nariman
Poushin.
- Support for overriding cache state via the debugfs implementation
from Richard Fitzgerald"

git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm updates from Dan Williams:
"This update has successfully completed a 0day-kbuild run and has
appeared in a linux-next release. The changes outside of the typical
drivers/nvdimm/ and drivers/acpi/nfit.[ch] paths are related to the
removal of IORESOURCE_CACHEABLE, the introduction of memremap(), and
the introduction of ZONE_DEVICE + devm_memremap_pages().
Summary:
- Introduce ZONE_DEVICE and devm_memremap_pages() as a generic
mechanism for adding device-driver-discovered memory regions to the
kernel's direct map.
This facility is used by the pmem driver to enable pfn_to_page()
operations on the page frames returned by DAX ('direct_access' in
'struct block_device_operations').
For now, the 'memmap' allocation for these "device" pages comes
from "System RAM". Support for allocating the memmap from device
memory will arrive in a later kernel.
- Introduce memremap() to replace usages of ioremap_cache() and
ioremap_wt(). memremap() drops the __iomem annotation for these
mappings to memory that do not have i/o side effects. The
replacement of ioremap_cache() with memremap() is limited to the
pmem driver to ease merging the api change in v4.3.
Completion of the conversion is targeted for v4.4.
- Similar to the usage of memcpy_to_pmem() + wmb_pmem() in the pmem
driver, update the VFS DAX implementation and PMEM api to provide
persistence guarantees for kernel operations on a DAX mapping.
- Convert the ACPI NFIT 'BLK' driver to map the block apertures as
cacheable to improve performance.
- Miscellaneous updates and fixes to libnvdimm including support for
issuing "address range scrub" commands, clarifying the optimal
'sector size' of pmem devices, a clarification of the usage of the
ACPI '_STA' (status) property for DIMM devices, and other minor
fixes"

According to datasheet, the S2MPS13X and S2MPS14X should update write
buffer via setting WUDR bit to high after ctrl register is written.
If not, ALARM interrupt of rtc-s5m doesn't happen first time when i use
tools/testing/selftests/timers/rtctest.c test program and hour format is
used to 12 hour mode in Odroid-XU3 board.
One more issue is the RTC doesn't keep time on Odroid-XU3 board when i
turn on board after power off even if RTC battery is connected. It can
be solved as setting WUDR & RUDR bits to high at the same time after
RTC_CTRL register is written. It's same with condition of only writing
ALARM registers, so this is for only S2MPS14 and we should set WUDR &
A_UDR bits to high on S2MPS13.
I can't find any reasonable description about this like fix from
datasheet, but can find similar codes from rtc driver source of
hardkernel kernel and vendor kernel.

SA1100 and PXA differ only in register offsets which are currently
hardcoded in a machine specific header. Some arm64 platforms (PXA1928)
have this RTC block as well (and not the PXA270 variant).
Convert the driver to use ioremap and set the register offsets dynamically.
Since we are touching all the register accesses, convert them all to
readl_relaxed/writel_relaxed.

Currently, the rtc-sa1100 and rtc-pxa drivers co-exist as rtc-pxa has a
superset of functionality. Having 2 drivers sharing the same memory
resource is not allowed by the driver model if resources are properly
declared. This problem was avoided by not adding memory resources to the
SA1100 RTC driver, but that prevents clean-up of the SA1100 driver.
This commit converts the PXA RTC to use the exported SA1100 RTC
functions. Now the sa1100-rtc and pxa-rtc devices are mutually
exclusive, so we must remove the sa1100-rtc from pxa27x and pxa3xx.

The clock enable/disable codes for alarm have been removed from
commit 24e1455493da ("drivers/rtc/rtc-s3c.c: delete duplicate clock
control") and the clocks are disabled even if alarm is set, so alarm
interrupt can't happen.
The s3c_rtc_setaie function can be called several times with 'enabled'
argument having same value, so it needs to check whether clocks are
enabled or not.

According to the Armada38x functional errata FE-3124064, writing to
the RTC TIME register may fail. As a workaround, after writing to RTC
TIME register, issue a dummy write of 0x0 twice to the RTC Status
register. This is the updated implementation of the Errata that
eliminates the need of the long 100ms delay during the RTC set time
procedure.
