Power-on Reset has a documented issue in PCF85063, refer to its datasheet,
section "Software reset":
"There is a low probability that some devices will have corruption of the
registers after the automatic power-on reset if the device is powered up
with a residual VDD level. It is required that the VDD starts at zero volts
at power up or upon power cycling to ensure that there is no corruption of
the registers. If this is not possible, a reset must be initiated after
power-up (i.e. when power is stable) with the software reset command"
Trigger SW reset if there is an indication that POR has failed.

Use the `DEFINE_RAW_FLEX()` helper for an on-stack definition of
a flexible structure where the size of the flexible-array member
is known at compile-time, and refactor the rest of the code,
accordingly.
So, with these changes, fix the following warning:
drivers/rtc/rtc-cros-ec.c:62:40: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]

The hardware alarm only supports one-minute accuracy which is coarse and
disables UIE usage. Use the 1-second interrupt to achieve per-second
accuracy. It is activated once we hit the per-minute alarm. The new
feature is optional. When there is no 1-second interrupt, old behaviour
with per-minute accuracy is used as before. With this feature, all tests
of 'rtctest' are successfully passed.

On many Qualcomm platforms the PMIC RTC control and time registers are
read-only so that the RTC time can not be updated. Instead an offset
needs be stored in some machine-specific non-volatile memory, which the
driver can take into account.
On machines like the Lenovo ThinkPad X13s the PMIC RTC drifts about one
second every 3.5 hours, something which leads to repeated updates of the
offset when NTP synchronisation is enabled.
Reduce wear of the underlying flash storage (used for UEFI variables) by
deferring writes until shutdown in case they appear to be due to clock
drift.
As an example, deferring writes when the new offset differs up to 30 s
from the previous one reduces the number of writes on the X13s during a
ten day session with the machine not suspending for more than four days
in a row from up to 68 writes (every 3.5 h) to at most two (boot and
shutdown).

read-only so that the RTC time can not be updated. Instead an offset
needs be stored in some machine-specific non-volatile memory, which the
driver can take into account.
Add support for storing a 32-bit offset from the GPS time epoch in a
UEFI variable so that the RTC time can be set on such platforms.
The UEFI variable is
882f8c2b-9646-435f-8de5-f208ff80c1bd-RTCInfo
and holds a 12-byte structure where the first four bytes is a GPS time
offset in little-endian byte order.
Note that this format is not arbitrary as the variable is shared with
the UEFI firmware (and Windows).

If the RTC is not enabled and the code attempts to disable the interrupt,
the readb_poll_timeout_atomic() function in the
rtca3_alarm_irq_set_helper() may timeout, leading to probe failures.
This issue is reproducible on some devices because the initial values of
the PIE and AIE bits in the RCR1 register are undefined.
To prevent probe failures in this scenario, disable RTC interrupts only
when the RTC is actually enabled.

The memory pointed to by the ::rtc member is managed via devres, and
no code in this driver uses it past _probe().
We can drop it from the structure and just use a local temporary
variable, reducing runtime memory consumption by a few bytes.
Since this now means that the structure has just one member only left,
there is no need anymore to allocate data for it and pass that around
via the various callbacks, just to extract that one member.
Instead, we can just pass that one member and avoid the extra memory
allocation for the containing struct, reducing runtime memory
consumption.

Pull turbostat updates from Len Brown:
- Fix regression that affinitized forked child in one-shot mode.
- Harden one-shot mode against hotplug online/offline
- Enable RAPL SysWatt column by default
- Add initial PTL, CWF platform support
- Harden initial PMT code in response to early use
- Enable first built-in PMT counter: CWF c1e residency
- Refuse to run on unsupported platforms without --force, to encourage
updating to a version that supports the system, and to avoid
no-so-useful measurement results

Pull sh updates from John Paul Adrian Glaubitz:
"Fixes and improvements for sh:
- replace seq_printf() with the more efficient
seq_put_decimal_ull_width() to increase performance when stress
reading /proc/interrupts (David Wang)
- migrate sh to the generic rule for built-in DTB to help avoid race
conditions during parallel builds which can occur because Kbuild
decends into arch/*/boot/dts twice (Masahiro Yamada)
- replace select with imply in the board Kconfig for enabling
hardware with complex dependencies. This addresses warnings which
were reported by the kernel test robot (Geert Uytterhoeven)"
* tag 'sh-for-v6.14-tag1' of git://git.kernel.org/pub/scm/linux/kernel/git/glaubitz/sh-linux:
sh: boards: Use imply to enable hardware with complex dependencies
sh: Migrate to the generic rule for built-in DTB
sh: irq: Use seq_put_decimal_ull_width() for decimal values
