Most of the changes again are devicetree fixes, but there are also five
trivial build fixes for issues I found when test building with gcc-11 or
when running 'make W=1', and some OMAP platform specific code fixups.
Broadcom
- One revert for a Raspberry pi interrupt controller change that
caused a regression.
TI OMAP:
- Remove unused duplicate sha2md5_fck clock node that can race with the
OMAP4_SHA2MD5_CLKCTRL clock node for disable for unused clocks
- Add aliases for omap4/5 mmc to put the slots back into the right
order again
- Fix typo for bionic voltage controllers that accidentally use mpu
for all instances instead of mpu, core and iva
- Fix random hangs for droid4 caused by missing fix from TI Android
kernel tree to do a dummy smc call on cpuidle wakeup path
NXP i.MX:
- Fix a system failure on imx6qdl-phytec-pfla02 board when booting from
SD, by adding missing vmmc supply for SD interfaces.
- Fix address typo in i.MX8MM/Q IOMUXC_SD1_DATA0_GPIO2_IO2 definition.
Marvell mvebu:
- Fix storm interrupt on Turris Omnia
- Enable hardware buffer management as it should be

Yanhui found that write performance is degraded a lot after applying
hctx shared tagset on one test machine with megaraid_sas. And turns out
it is caused by none scheduler which becomes default elevator caused by
hctx shared tagset patchset.
Given more scsi HBAs will apply hctx shared tagset, and the similar
performance exists for them too.
So keep previous behavior by still using default mq-deadline for queues
which apply hctx shared tagset, just like before.

This patch adds support for AHCI-compliant Serial ATA controller
on Tegra186 SoC.
Tegra186 does not have sata-oob reset.
Tegra186 SATA_NVOOB register filed COMMA_CNT position and width are
different compared to Tegra210 and prior.
So, this patch adds a flag has_sata_oob_rst and tegra_ahci_regs to
SoC specific strcuture tegra_ahci_soc and updated their implementation
accordingly.

When the period is small, using all the FRDDR fifo depth increases the
latency of the playback because the following device won't start pulling
data until the fifo reaches the depth set. We can adjust this depth so trim
it down for small periods.

When a VCPU is created, the kvm_vcpu struct is initialized to zero in
kvm_vm_ioctl_create_vcpu(). On VHE systems, the first time
vcpu.arch.mdcr_el2 is loaded on hardware is in vcpu_load(), before it is
set to a sensible value in kvm_arm_setup_debug() later in the run loop. The
result is that KVM executes for a short time with MDCR_EL2 set to zero.
This has several unintended consequences:
* Setting MDCR_EL2.HPMN to 0 is constrained unpredictable according to ARM
DDI 0487G.a, page D13-3820. The behavior specified by the architecture
in this case is for the PE to behave as if MDCR_EL2.HPMN is set to a
value less than or equal to PMCR_EL0.N, which means that an unknown
number of counters are now disabled by MDCR_EL2.HPME, which is zero.
* The host configuration for the other debug features controlled by
MDCR_EL2 is temporarily lost. This has been harmless so far, as Linux
doesn't use the other fields, but that might change in the future.
Let's avoid both issues by initializing the VCPU's mdcr_el2 field in
kvm_vcpu_vcpu_first_run_init(), thus making sure that the MDCR_EL2 register
has a consistent value after each vcpu_load().

Currently, there is no mechanism to keep time sync between guest and host
in arm/arm64 virtualization environment. Time in guest will drift compared
with host after boot up as they may both use third party time sources
to correct their time respectively. The time deviation will be in order
of milliseconds. But in some scenarios,like in cloud environment, we ask
for higher time precision.
kvm ptp clock, which chooses the host clock source as a reference
clock to sync time between guest and host, has been adopted by x86
which takes the time sync order from milliseconds to nanoseconds.
This patch enables kvm ptp clock for arm/arm64 and improves clock sync precision
significantly.
Test result comparisons between with kvm ptp clock and without it in arm/arm64
are as follows. This test derived from the result of command 'chronyc
sources'. we should take more care of the last sample column which shows
the offset between the local clock and the source at the last measurement.
no kvm ptp in guest:

System time snapshots are not conveying information about the current
clocksource which was used, but callers like the PTP KVM guest
implementation have the requirement to evaluate the clocksource type to
select the appropriate mechanism.
Introduce a clocksource id field in struct clocksource which is by default
set to CSID_GENERIC (0). Clocksource implementations can set that field to
a value which allows to identify the clocksource.
Store the clocksource id of the current clocksource in the
system_time_snapshot so callers can evaluate which clocksource was used to
take the snapshot and act accordingly.
