Pull irq updates from Thomas Gleixner:
"The interrupt departement provides:
- A mechanism to shield isolated tasks from managed interrupts:
The affinity of managed interrupts is completely controlled by the
kernel and user space has no influence on them. The reason is that
the automatically assigned affinity correlates to the multi-queue
CPU handling of block devices.
If the generated affinity mask spaws both housekeeping and isolated
CPUs the interrupt could be routed to an isolated CPU which would
then be disturbed by I/O submitted by a housekeeping CPU.
The new mechamism ensures that as long as one housekeeping CPU is
online in the assigned affinity mask the interrupt is routed to a
housekeeping CPU.
If there is no online housekeeping CPU in the affinity mask, then
the interrupt is routed to an isolated CPU to keep the device queue
intact, but unless the isolated CPU submits I/O by itself these
interrupts are not raised.
- A small addon to the device tree irqdomain core code to avoid
duplication in irq chip drivers
- Conversion of the SiFive PLIC to hierarchical domains
- The usual pile of new irq chip drivers: SiFive GPIO, Aspeed SCI,
NXP INTMUX, Meson A1 GPIO
- The first cut of support for the new ARM GICv4.1
- The usual pile of fixes and improvements in core and driver code"

Pull timer updates from Thomas Gleixner:
"The timekeeping and timers departement provides:
- Time namespace support:
If a container migrates from one host to another then it expects
that clocks based on MONOTONIC and BOOTTIME are not subject to
disruption. Due to different boot time and non-suspended runtime
these clocks can differ significantly on two hosts, in the worst
case time goes backwards which is a violation of the POSIX
requirements.
The time namespace addresses this problem. It allows to set offsets
for clock MONOTONIC and BOOTTIME once after creation and before
tasks are associated with the namespace. These offsets are taken
into account by timers and timekeeping including the VDSO.
Offsets for wall clock based clocks (REALTIME/TAI) are not provided
by this mechanism. While in theory possible, the overhead and code
complexity would be immense and not justified by the esoteric
potential use cases which were discussed at Plumbers '18.
The overhead for tasks in the root namespace (ie where host time
offsets = 0) is in the noise and great effort was made to ensure
that especially in the VDSO. If time namespace is disabled in the
kernel configuration the code is compiled out.
Kudos to Andrei Vagin and Dmitry Sofanov who implemented this
feature and kept on for more than a year addressing review
comments, finding better solutions. A pleasant experience.
- Overhaul of the alarmtimer device dependency handling to ensure
that the init/suspend/resume ordering is correct.
- A new clocksource/event driver for Microchip PIT64
- Suspend/resume support for the Hyper-V clocksource
- The usual pile of fixes, updates and improvements mostly in the

Current dts files with 'dwmmc' nodes are manually verified.
In order to automate this process rockchip-dw-mshc.txt
has to be converted to yaml. In the new setup
rockchip-dw-mshc.yaml will inherit properties from
mmc-controller.yaml and synopsys-dw-mshc-common.yaml.
'dwmmc' will no longer be a valid name for a node and
should be changed to 'mmc'.

Current dts files with 'dwmmc' nodes are manually verified.
In order to automate this process synopsys-dw-mshc.txt
has to be converted to yaml. In the new setup
synopsys-dw-mshc.yaml will inherit properties from
mmc-controller.yaml and synopsys-dw-mshc-common.yaml.
'dwmmc' will no longer be a valid name for a node and
should be changed to 'mmc'.

Add an entry for erratum A011043: the MDIO_CFG[MDIO_RD_ER]
bit may be falsely set when reading internal PCS registers.
MDIO reads to internal PCS registers may result in having
the MDIO_CFG[MDIO_RD_ER] bit set, even when there is no
error and read data (MDIO_DATA[MDIO_DATA]) is correct.
Software may get false read error when reading internal
PCS registers through MDIO. As a workaround, all internal
MDIO accesses should ignore the MDIO_CFG[MDIO_RD_ER] bit.

Pull devfreq updates for v5.6 from Chanwoo Choi:
"1. Update devfreq core
- Add new 'name' attribute of sysfs to show the device name
: /sys/class/devfreq/devfreqX/name
- Make 'trans_stat' sysfs reset by entering zero(0)
: echo 0 > /sys/class/devfreq/devfreqX/trans_stat
- Add debugfs support with 'devfreq_summary' to show the summary
: /sys/kernel/debug/devfreq/devfreq_summary
- Change the type of time variable to 64bit to avoid overflows.
- Make separate devfreq_stats including the statistics information.
- Fix minor coding-style like indentation and kernel-doc warnings.
2. Update devfreq drivers
- Add new imx8m-ddrc.c devfreq driver for dynamic scaling of DDR frequency.
It changes the DDR frequency by using ARM SMCCC(SMC Calling Convention)
interface to control TF-A firmware.
- Add COMPILE_TEST dependency for rk3399_dmc.c.
- Clean-up code for exynos-bus.c and rk3399_dmc.c without behavior changes
3. Update devfreq-event drivers
- Fix excessive stack usage of exynos-ppmu.c and clean-up code of
rockchip-dfi.c without behavior changes."

Add driver for Microchip PIT64B timer. Timer could be used in continuous
mode or oneshot mode. The hardware has 2x32 bit registers for period
emulating a 64 bit timer. The LSB_PR and MSB_PR registers are used to
set the period value (compare value). TLSB and TMSB keeps the current
value of the counter. After a compare the TLSB and TMSB register resets.
The driver uses PIT64B timer for clocksource or clockevent. First
requested timer would be registered as clockevent, second one would be
registered as clocksource. Individual PIT64B hardware resources were
used for clocksource and clockevent to be able to support high resolution
timers with this hardware implementation.
