then proceeded to list register values in its device tree binding

However, the macros used with the Mediatek pinctrl bindings directly
specify the drive strength in micro-amps, instead of hardware register
values. The current driver implementation in Linux does convert the
value from micro-amps to hardware register values. This implementation
is also used with MT7622 and MT8183, which use real world values in
their device trees.

Given the above, it was likely an oversight to use the raw register
values in the binding. Correct the values in the binding. Also drop
the description since the binding combined with its parent,
pinctrl/pincfg.yaml, the binding is now self-describing.

pinctrl: renesas: Fix pin control matching on R-Car H3e-2G

As R-Car H3 ES1.x (R8A77950) and R-Car ES2.0+ (R8A77951) use the same
compatible value, the pin control driver relies on soc_device_match()
with soc_id = "r8a7795" and the (non)matching of revision = "ES1.*" to
match with and distinguish between the two SoC variants.  The
corresponding entries in the normal of_match_table are present only to
make the optional sanity checks work.

The R-Car H3e-2G (R8A779M1) SoC is a different grading of the R-Car H3
ES3.0 (R8A77951) SoC.  It uses the same compatible values for individual
devices, but has an additional compatible value for the root node.
When running on an R-Car H3e-2G SoC, soc_device_match() with soc_id =
"r8a7795" does not return a match.  Hence the pin control driver falls
back to the normal of_match_table, and, as the R8A77950 entry is listed
first, incorrectly uses the sub-driver for R-Car H3 ES1.x.

Fix this by moving the entry for R8A77951 before the entry for R8A77950.
Simplify sh_pfc_quirk_match() to only handle R-Car H3 ES1,x, as R-Car H3
ES2.0+ can now be matched using the normal of_match_table as well.

pinctrl: armada-37xx: Correct PWM pins definitions

The PWM pins on North Bridge on Armada 37xx can be configured into PWM
or GPIO functions. When in PWM function, each pin can also be configured
to drive low on 0 and tri-state on 1 (LED mode).

The current definitions handle this by declaring two pin groups for each
pin:
- group "pwmN" with functions "pwm" and "gpio"
- group "ledN_od" ("od" for open drain) with functions "led" and "gpio"

This is semantically incorrect. The correct definition for each pin
should be one group with three functions: "pwm", "led" and "gpio".

Change the "pwmN" groups to support "led" function.

Remove "ledN_od" groups. This cannot break backwards compatibility with
older device trees: no device tree uses it since there is no PWM driver
for this SOC yet. Also "ledN_od" groups are not even documented.

mm/rmap: fix old bug: munlocking THP missed other mlocks

The kernel recovers in due course from missing Mlocked pages: but there
was no point in calling page_mlock() (formerly known as
try_to_munlock()) on a THP, because nothing got done even when it was
found to be mapped in another VM_LOCKED vma.

It's true that we need to be careful: Mlocked accounting of pte-mapped
THPs is too difficult (so consistently avoided); but Mlocked accounting
of only-pmd-mapped THPs is supposed to work, even when multiple mappings
are mlocked and munlocked or munmapped.  Refine the tests.

There is already a VM_BUG_ON_PAGE(PageDoubleMap) in page_mlock(), so
page_mlock_one() does not even have to worry about that complication.

(I said the kernel recovers: but would page reclaim be likely to split
THP before rediscovering that it's VM_LOCKED? I've not followed that up)

Merge tag 'perf-tools-for-v5.14-2021-07-10' of git://git./linux/kernel/git/acme/linux

Pull more perf tool updates from Arnaldo Carvalho de Melo:
 "New features:

   - Enable use of BPF counters with 'perf stat --for-each-cgroup',
     using per-CPU 'cgroup-switch' events with an attached BPF program
     that does aggregation per-cgroup in the kernel instead of using
     per-cgroup perf events.

   - Add Topdown metrics L2 events as default events in 'perf stat' for
     systems having those events.

  Hardware tracing:

   - Add a config for max loops without consuming a packet in the Intel
     PT packet decoder, set via 'perf config intel-pt.max-loops=N'

  Hardware enablement:

   - Disable misleading NMI watchdog message in 'perf stat' on hybrid
     systems such as Intel Alder Lake.

   - Add a dummy event on hybrid systems to collect metadata records.

   - Add 24x7 nest metric events for the Power10 platform.

  Fixes:

   - Fix event parsing for PMUs starting with the same prefix.

   - Fix the 'perf trace' 'trace' alias installation dir.

   - Fix buffer size to report iregs in perf script python scripts,
     supporting the extended registers in PowerPC.

   - Fix overflow in elf_sec__is_text().

   - Fix 's' on source line when disasm is empty in the annotation TUI,
     accessible via 'perf annotate', 'perf report' and 'perf top'.

   - Plug leaks in scandir() returned dirent entries in 'perf test' when
     sorting the shell tests.

   - Fix --task and --stat with pipe input in 'perf report'.

   - Fix 'perf probe' use of debuginfo files by build id.

   - If a DSO has both dynsym and symtab ELF sections, read from both
     when loading the symbol table, fixing a problem processing Fedora
     32 glibc DSOs.

  Libraries:

   - Add grouping of events to libperf, from code in tools/perf,
     allowing libperf users to use that mode.

  Misc:

   - Filter plt stubs from the 'perf probe --functions' output.

   - Update UAPI header copies for asound, DRM, mman-common.h and the
     ones affected by the quotactl_fd syscall"

added support for timestamp interrupts. However they are not being
handled in the irq handler. If a timestamp interrupt occurs it
results in kernel disabling the interrupt and displaying the call
trace:

[  121.248971] Disabling IRQ #78

Handle timestamp interrupts in pcf2127_rtc_irq(). Save time stamp
before clearing TSF1 and TSF2 flags so that it can't be overwritten.
Set a flag to mark if the timestamp is valid and only report to sysfs
if the flag is set. To mimic the hardware behavior, don’t save
another timestamp until the first one has been read by the userspace.

However, if the alarm irq is not configured, keep the old way of
handling timestamp interrupt in the timestamp0 sysfs calls.
