Large part of the code uses the FIELD_PREP() macro already to construct
values to be written to hardware registers. Change the code to use also
the macro for more registers of which the corresponding bitmasks are
defined already.
This makes the code more readable. It also syncs the affected
codes with their counterparts in the 'qcom_nandc' driver, so it
makes it easier to spot the differences between the two
implementations.
No functional changes intended.

In the recently added snd_soc_dlc_is_dummy(), the helper uses the .name
and .dai_name fields without checking their validity.
For .name, this field is NULL if the component is matched by .of_node
instead. In fact, only one of these fields may be set. This caused a
NULL pointer dereference on MediaTek MT8195 and MT8188 platforms with
the subsequent conversion to snd_soc_dlc_is_dummy() in their machine
drivers. The codecs are all matches through the device tree, so their
.name fields are empty.
For .dai_name, there are cases where this field is empty, such as for
the following component definitions:
#define COMP_EMPTY() { }
#define COMP_PLATFORM(_name) { .name = _name }
#define COMP_AUX(_name) { .name = _name }
#define COMP_CODEC_CONF(_name) { .name = _name }
Or the single link CPU DAI case in the simple audio card family, as
covered by simple_util_canonicalize_cpu(), in which the .dai_name
field is explicitly cleared.
To fix this, check the validity of the fields before using them in
string comparison.

Add support for Airoha EN7581 thermal sensor. This provide support for
reading the CPU or SoC Package sensor and to setup trip points for hot
and critical condition. An interrupt is fired to react on this and
doesn't require passive poll to read the temperature.
The thermal regs provide a way to read the ADC value from an external
register placed in the Chip SCU regs. Monitor will read this value and
fire an interrupt if the trip condition configured is reached.
The Thermal Trip and Interrupt logic is conceptually similar to Mediatek
LVTS Thermal but differ in register mapping and actual function/bug
workaround. The implementation only share some register names but from
functionality observation it's very different and used only for the
basic function of periodically poll the temp and trip the interrupt.

When running the probe function for this driver, the function
lvts_debugfs_init() gets called in lvts_domain_init() which, in
turn, gets called in lvts_probe() before registering threaded
interrupt handlers.
Even though it's unlikely, the last call may fail and, if it does,
there's nothing removing the already created debugfs folder and
files.
In order to fix that, instead of calling the lvts debugfs cleanup
function upon failure, register a devm action that will take care
of calling that upon failure or driver removal.
Since devm was used, also delete the call to lvts_debugfs_exit()
in the lvts_remove() callback, as now that's done automatically.

The resctrl pseudo-lock feature allows an architecture to allocate data
into particular cache portions, which are then treated as reserved to
avoid that data ever being evicted. Setting this up is deeply architecture
specific as it involves disabling prefetchers etc. It is not possible
to support this kind of feature on arm64. Risc-V is assumed to be the
same.
The prototypes for the architecture code were added to x86's asm/resctrl.h,
with other architectures able to provide stubs for their architecture. This
forces other architectures to provide identical stubs.
Move the prototypes and stubs to linux/resctrl.h, and switch between them

Introduce a clocksource driver for the so-called high-precision timer (HPT)
in the EcoNet EN751221 and EN751627 MIPS SoCs.
It's a 32 bit upward-counting one-shot timer which relies on the crystal so it
is unaffected by CPU power mode. On MIPS 34K devices (single core) there is
one timer, and on 1004K devices (dual core) there are two.
Each timer has two sets of count/compare registers so that there is one for
each of the VPEs on the core. Because each core has 2 VPEs, register selection
takes the CPU number / 2 for the timer corrisponding to the core, then CPU
number % 2 for the register corrisponding to the VPE.
These timers use a percpu-devid IRQ to route interrupts to the VPE which set
the event.

This change removes watchdog self-pinging behavior.
The timer irq handler is triggered due to the 1st expiration,
the handler disables and enables watchdog but also implicitly
clears the expiration count so the count can only be 0 or 1.
Since this watchdog supports opened, configured, or pinged by
systemd, We remove this behavior or the watchdog may not bark
when systemd crashes since the 5th expiration never comes.

This change adds support for WDIOC_GETTIMELEFT so userspace
programs can get the number of seconds before system reset by
the watchdog timer via ioctl.
