Pull clk updates from Stephen Boyd:
"Not much changed in the clk framework this time except the clk.h
consumer API moved the context saving APIs around to fix a build error
in certain configurations.
There was a change to the core framework for CLK_OPS_PARENT_ENABLE
behavior during registration, but it wrecked existing drivers that
didn't expect things to be turned off during clk registration so it
got reverted.
This cycle is really a large collection of new clk drivers, primarily
for Qualcomm SoCs but also for Amlogic, SpacemiT, Google, and Aspeed.
Another big change in here is support for automatic hardware clock
gating on Samsung SoCs where the clks turn on and off when needed.
Ideally more vendors move to this method for better power savings. The
highlights are in the updates section below.
Beyond all the new drivers we have a bunch of cleanups like converting
drivers from divider_round_rate() to divider_determine_rate() and
using scoped for each OF child loops. Otherwise it's the usual data
fixes and plugging reference leaks, etc. that's all pretty ordinary
but not critical enough to fix until the next release.
New Drivers:
- Qualcomm Kaanapali global, tcsr, rpmh, display, gpu, camera, and
video clk controllers
- Qualcomm SM8750 camera clk controllers
- Qualcomm MSM8940 and SDM439 global clk controllers
- Google GS101 Display Process Unit (DPU) clk controllers
- SpacemiT K3 clk controllers
- Amlogic t7 clk controllers
- Aspeed AST2700 clk controllers
Updates:
- Convert clock dividers from round_rate() to determine_rate()
- Fix sparse warnings, kernel-doc warnings, and plug leaked OF refs
- Automatic hardware clk gating on Google GS101 SoCs
- Amlogic s4 video clks
- CAN-FD clks and resets on Renesas RZ/T2H, RZ/N2H, RZ/V2H, and
RZ/V2N
- Expanded Serial Peripheral Interface (xSPI) clocks and resets on
Renesas RZ/T21H and RZ/N2H
- DMAC, interrupt controller (ICU), SPI, and thermal (TSU) clocks and
resets on Renesas RZ/V2N
- More serial (RSCI) clocks and resets on Renesas RZ/V2H and RZ/V2N
- CPU frequency scaling on T-HEAD TH1520"

Passing IRQF_ONESHOT ensures that the interrupt source is masked until
the secondary (threaded) handler is done. If only a primary handler is
used then the flag makes no sense because the interrupt can not fire
(again) while its handler is running.
The flag also prevents force-threading of the primary handler and the
irq-core will warn about this.
Remove IRQF_ONESHOT from irqflags.

RTC_DRV_SPACEMIT_P1 is a subdevice of P1 and should depend on
MFD_SPACEMIT_P1 rather than selecting it directly. Using 'select'
does not always respect the parent's dependencies, so 'depends on'
is the safer and more correct choice.
Additionally, the default value depends on MFD_SPACEMIT_P1 rather
than ARCH_SPACEMIT.

Apple Silicon Macs (M1, etc.) have an RTC that is part of the PMU IC,
but most of the PMU functionality is abstracted out by the SMC.
On T600x machines, the RTC counter must be accessed via the SMC to
get full functionality, and it seems likely that future machines
will move towards making SMC handle all RTC functionality.
The SMC RTC counter access is implemented on all current machines
as of the time of this writing, on firmware 12.x. However, the RTC
offset (needed to set the time) is still only accessible via direct
PMU access. To handle this, we expose the RTC offset as an NVMEM
cell from the SPMI PMU device node, and this driver consumes that
cell and uses it to compute/set the current time.

The register buffer in s35390a_get_reg() was previously defined as
`char *buf`. This is not ideal since register data represents raw
binary values rather than textual data.
Switch the type to `u8 *buf` to better reflect its intended usage and
to avoid potential issues with sign extension when handling register
values on platforms where `char` is signed by default.
This change improves type safety and makes the code consistent with
other RTC drivers that operate on raw register data.

driver. NVIDIA VRS is a Power Management IC (PMIC) that implements a
power sequencing solution with I2C interface. The device includes RTC
which provides functionality to get/set system time, retain system
time across boot, wake system from suspend and shutdown state.
Supported platforms:
- NVIDIA Jetson AGX Orin Developer Kit
- NVIDIA IGX Orin Development Kit
- NVIDIA Jetson Orin NX Developer Kit
- NVIDIA Jetson Orin Nano Developer Kit

The clock obtained via devm_clk_get_enabled() is automatically managed
by devres and will be disabled and freed on driver detach. Manually
calling clk_disable_unprepare() in error path and remove function
causes double free.
Remove the redundant clk_disable_unprepare() calls from the probe
error path and aml_rtc_remove(), allowing the devm framework to
automatically manage the clock lifecycle.

Commit e0762fd26ad6 ("rtc: cpcap: Fix initial enable_irq/disable_irq
balance") set 'alarm_enabled' prior to calling the function
devm_request_threaded_irq() because this enables the IRQ. However, right
after calling devm_request_threaded_irq(), the driver calls
disable_irq() to disable the IRQ and so now 'alarm_enabled' will be true
but the IRQ is actually disabled. Revert this commit to fix the
'alarm_enabled' state.

Commit 1502fe0e97be ("rtc: tps6586x: Fix initial enable_irq/disable_irq
balance") breaks the wake-up alarm for the tps6586x. After this commit
was added RTC wake ups from suspend stopped working on the Tegra20
Ventana platform.
The problem is that this change set the 'irq_en' variable to true prior
to calling devm_request_threaded_irq() to indicate that the IRQ is
enabled, however, it was over looked that the flag IRQ_NOAUTOEN is
already set meaning that the IRQ is not enabled by default. This
prevents the IRQ from being enabled as expected. Revert this change to
fix this.

When setting a normal alarm, user-space is responsible for using
RTC_AIE_ON/RTC_AIE_OFF to control if alarm irq should be enabled.
But when RTC_UIE_ON is used, interrupts must be enabled so that the
requested irq events are generated.
When RTC_UIE_OFF is used, alarm irq is disabled if there are no other
alarms queued, so this commit brings symmetry to that.

As described in the old comment dating back to
commit 6610e0893b8b ("RTC: Rework RTC code to use timerqueue for events")
from 2010, we have been living with a race window when setting alarm
with an expiry in the near future (i.e. next second).
With 1 second resolution, it can happen that the second ticks after the
check for the timer having expired, but before the alarm is actually set.
When this happen, no alarm IRQ is generated, at least not with some RTC
chips (isl12022 is an example of this).
With UIE RTC timer being implemented on top of alarm irq, being re-armed
every second, UIE will occasionally fail to work, as an alarm irq lost
due to this race will stop the re-arming loop.
For now, I have limited the additional expiry check to only be done for
alarms set to next seconds. I expect it should be good enough, although I
don't know if we can now for sure that systems with loads could end up
causing the same problems for alarms set 2 seconds or even longer in the
future.
I haven't been able to reproduce the problem with this check in place.

When using interrupt pin (INT A) as watchdog output all other
interrupt sources need to be disabled to avoid additional
resets. Resulting INT_A_MASK1 value is 55 (0x37).
