Apple SoC DTS changes for 7.3
- Initial M3 Pro, Max and Ultra device trees, which are responsible for
the majority of the diffstat. These include CPU cores, interrupt
controller, power state, watchdog, serial pin/gpio controller, i2c and
the boot framebuffer. They are now on par with the base M3 device
trees.
- HWMON sensors for M1/M2
- "pmgr-misc" nodes for M1/2 Pro/Max/Ultra which saves about 1W of power
on these machines. The corresponding driver and dt-binding are part of
the Apple SoC driver changes tag for this cycle.

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap
Pull regmap fixes from Mark Brown:
"These fix some issues which were noticed in some drivers where caches
were not fully resynced after suspend. Drivers are supposed to be
sorting the table of register defaults they provide to the core and
the core was relying on that but it turns out there are many cases
where this does not happen, it's easy to get wrong when using named
defines for registers rather than numbers. It is more robust to remove
the requirement for sorting and instead have the core ensure
everything it needs sorting is sorted so do that.
There will be patches during the merge window sorting the tables in
drivers since it is more efficient to do that but this will just be a
minor performance win rather than a correctness fix"

that no IRQ is available, while other errors should be propagated.

Commit 645ad41da8b2 ("watchdog: pretimeout: Add "dump" pretimeout
governor") added the "dump" watchdog pretimeout governor, but restricted
it to built-in code because trigger_all_cpu_backtrace() was not exported
to loadable modules.
Now that CPU backtrace APIs are supported for loadable kernel modules
via cpumask_backtrace(), convert WATCHDOG_PRETIMEOUT_GOV_DUMP to
tristate. This allows kernels to deliver the pretimeout governor as a
loadable kernel module.

Currently, CPU backtrace functions cannot be called from loadable
modules because the underlying helper arch_trigger_cpumask_backtrace()
is not exported.
Instead of exporting arch_trigger_cpumask_backtrace() individually
across every supported architecture, introduce and export a common
helper, cpumask_backtrace(), in lib/nmi_backtrace.c. Update the four
inline CPU backtrace macros in include/linux/nmi.h to route through this
centralized helper.

Some firmwares describe WDAT registers inside memory ranges marked as
ACPI NVS in the E820 map, failing with -EBUSY during probe, leaving the
hardware watchdog unserviced and triggering periodic system resets.
This issue was observed on a OnLogic Karbon 524 device (when watchdog is
enabled in BIOS):
wdat_wdt wdat_wdt: error -EBUSY: can't request region for resource [mem 0x63df7a98]
wdat_wdt wdat_wdt: probe with driver wdat_wdt failed with error -16
Check whether the region falls inside ACPI NVS before requesting it and,
if so, map it without reservation.

If some, but not all, watchdog devices have device tree aliases, those
without aliases might (depending on probe order) be assigned an id
which would otherwise be assigned to one of those with an alias.
This is problematic when for example watchdog0 is an alias for an
always-running gpio watchdog that userspace must handle, but the SOC's
watchdog device(s) get probed first and thus one of those become
/dev/watchdog0, and then at some point later, the gpio watchdog device
gets probed and becomes /dev/watchdog5.
Ensure that ids for devices without a device tree alias are allocated
from among those where no watchdogX alias exists.

The driver has a match table for the pci bus wired into its driver
structure, but the table is not exported with MODULE_DEVICE_TABLE().
Add the missing MODULE_DEVICE_TABLE() entry so module alias information
is generated for automatic module loading.
This is a source-level fix. It does not claim dynamic hardware
reproduction; the evidence is the driver-owned match table, its use by
the driver registration structure, and the missing module alias
publication.

To make the realtek watchdog driver functional when SWAP_IO_SPACE
config is enabled, change all of the register access to be done
by regmap API which helps us to tweak endianness with big-endian
or little-endian property from within the device tree node.
Add the REGMAP_MMIO as a select to REALTEK_OTTO_WDT now that the
regmap is used.

The NPCM750 uses RESSR and the NPCM845 uses INTCR2 to latch reset
indications. Read those bits during probe and map them into watchdog
bootstatus flags.
For NPCM845, cache the sampled INTCR2 state in SCRPAD10 after the reset
status bits are cleared so later probes can report the same boot-time
state. Also report WDIOF_CARDRESET for the watchdog instance whose reset
bit is latched, while leaving WPCM450 behavior unchanged.

NPCM750 and NPCM845 latch watchdog reset indications in the SoC
GCR block rather than in the watchdog block itself.
Add the optional nuvoton,sysgcr phandle so watchdog nodes can
reference the shared GCR reset-status registers that hold those
latched watchdog reset indications.
This is needed by the following reset-status support, which reads
those latches and reports watchdog-caused resets through bootstatus.

If the watchdog is already running when the driver is initialized, the
driver currently refreshes it once using the default timeout of 60
seconds.
Since commit ee142889e32f ("watchdog: Introduce WDOG_HW_RUNNING flag"),
the watchdog core can kick an already running watchdog alive until
userspace open the device.
Add the WDOG_HW_RUNNING flag to the watchdog status if the watchdog is
already running.

The watchdog identity string reported via WDIOC_GETSUPPORT has always
been hardcoded to "W83627HF Watchdog", even though this driver supports
a wide range of Nuvoton/Winbond Super I/O chips.
This is misleading, since the driver itself correctly log the chip name
in wdt_init(), but could report later a different chip name with
WDIOC_GETSUPPORT.
Instead format the identity at probe time using the actual chip name
that was detected.

Add a new "dump" pretimeout governor that triggers a backtrace of all
CPUs (via trigger_all_cpu_backtrace()) to the kernel log buffer. This
provides diagnostic information right before the hardware watchdog
fires.
In addition, update the WATCHDOG_PRETIMEOUT_GOV_SEL Kconfig logic to
fall back to the "panic" governor only when both "noop" and "dump"
governors are disabled.

Named initializers are better readable and more robust to changes of the
struct definition. This robustness is relevant for a planned change to
struct platform_device_id replacing .driver_data by an anonymous union.
For one driver drop the unused assignment to .driver_data instead.
While touching these arrays unify spacing and usage of commas.
There is no effect on the compiled arrays.
