The following build failure occurs when CONFIG_PERF_EVENTS is not set
as generic pmu functions are not visible in that scenario.
|-- s390-randconfig-r044-20220313
| |-- nd_perf.c:(.text):undefined-reference-to-perf_pmu_migrate_context
| |-- nd_perf.c:(.text):undefined-reference-to-perf_pmu_register
| `-- nd_perf.c:(.text):undefined-reference-to-perf_pmu_unregister
Similar build failure in nds32 architecture:
nd_perf.c:(.text+0x21e): undefined reference to `perf_pmu_migrate_context'
nd_perf.c:(.text+0x434): undefined reference to `perf_pmu_register'
nd_perf.c:(.text+0x57c): undefined reference to `perf_pmu_unregister'
Fix this issue by adding check for CONFIG_PERF_EVENTS config option
and disabling the nvdimm perf interface incase this config is not set.
Also remove function declaration of perf_pmu_migrate_context,
perf_pmu_register, perf_pmu_unregister functions from nd.h as these are
common pmu functions which are part of perf_event.h and since we
are disabling nvdimm perf interface incase CONFIG_PERF_EVENTS option
is not set, we not need to declare them in nd.h
Also move the platform_device header file addition part from nd.h to
nd_perf.c and add stub functions for register_nvdimm_pmu and
unregister_nvdimm_pmu functions to handle CONFIG_PERF_EVENTS=n
case.

While the RTC can store dates from year 0000 to 9999, leap years where not

H6 supports IOSC calibration and an ext-osc32k input. Unlike newer SoCs,

The RTC power domain in sun6i and newer SoCs manages the 16 MHz RC
oscillator (called "IOSC" or "osc16M") and the optional 32 kHz crystal
oscillator (called "LOSC" or "osc32k"). Starting with the H6, this power
domain also handles the 24 MHz DCXO (called variously "HOSC", "dcxo24M",
or "osc24M") as well. The H6 also adds a calibration circuit for IOSC.
Later SoCs introduce further variations on the design:
- H616 adds an additional mux for the 32 kHz fanout source.
- R329 adds an additional mux for the RTC timekeeping clock, a clock
for the SPI bus between power domains inside the RTC, and removes the
IOSC calibration functionality.
Take advantage of the CCU framework to handle this increased complexity.
This driver is intended to be a drop-in replacement for the existing RTC
clock provider. So some runtime adjustment of the clock parents is
needed, both to handle hardware differences, and to support the old
binding which omitted some of the input clocks.

Newer versions of the Allwinner RTC, for instance as found in the H616
SoC, not only store the current day as a linear number, but also change
the way the alarm is handled: There are now two registers, that
explicitly store the wakeup time, in the same format as the current
time.
Add support for that variant by writing the requested wakeup time
directly into the registers, instead of programming the seconds left, as
the old SoCs required.

Newer versions of the Allwinner RTC, as for instance found in the H616
SoC, no longer store a broken-down day/month/year representation in the
RTC_DAY_REG, but just a linear day number.
The user manual does not give any indication about the expected epoch
time of this day count, but the BSP kernel uses the UNIX epoch, which
allows easy support due to existing conversion functions in the kernel.
Allow tagging a compatible string with a flag, and use that to mark
those new RTCs. Then convert between a UNIX day number (converted into
seconds) and the broken-down day representation using mktime64() and
time64_to_tm() in the set_time/get_time functions.
That enables support for the RTC in those new chips.

Using "unsigned long" for UNIX timestamps is never a good idea, and
comparing the value of such a variable against U32_MAX does not do
anything useful on 32-bit systems.
Use the proper time64_t type when dealing with timestamps, and avoid
cutting down the time range unnecessarily. This also fixes the flawed
check for the alarm time being too far into the future.
The check for this condition is actually somewhat theoretical, as the
RTC counts till 2033 only anyways, and 2^32 seconds from now is not
before the year 2157 - at which point I hope nobody will be using this
hardware anymore.

cpsw_ethtool_begin directly returns the result of pm_runtime_get_sync
when successful.
pm_runtime_get_sync returns -error code on failure and 0 on successful
resume but also 1 when the device is already active. So the common case
for cpsw_ethtool_begin is to return 1. That leads to inconsistent calls
to pm_runtime_put in the call-chain so that pm_runtime_put is called
one too many times and as result leaving the cpsw dev behind suspended.
The suspended cpsw dev leads to an access violation later on by
different parts of the cpsw driver.
Fix this by calling the return-friendly pm_runtime_resume_and_get
function.

ice_send_event_to_aux() eventually descends to mutex_lock()
(-> might_sched()), so it must not be called under non-task
context. However, at least two fixes have happened already for the
bug splats occurred due to this function being called from atomic
context.
To make the emergency landings softer, bail out early when executed
in non-task context emitting a warn splat only once. This way we
trade some events being potentially lost for system stability and
avoid any related hangs and crashes.

ice_send_event_to_aux()
device_lock()
mutex_lock()

Add a new PF state bit which indicates that an aux critical error
occurred and serve it in ice_service_task() in process context.
The new ice_pf::oicr_err_reg is read-write in both hardirq and
process contexts, but only 3 bits of non-critical data probably
aren't worth explicit synchronizing (and they're even in the same
byte [31:24]).

CRC checksum. It's the responsability of the driver to strip those 4

This change re-orders that part a bit such that the datalen is

It is not recommened to use platform_get_resource(pdev, IORESOURCE_IRQ)
for requesting IRQ's resources any more, as they can be not ready yet in
case of DT-booting.
platform_get_irq() instead is a recommended way for getting IRQ even if
it was not retrieved earlier.
It also makes code simpler because we're getting "int" value right away
and no conversion from resource to int is required.
The print function dev_err() is redundant because platform_get_irq()
already prints an error.

x86/ACPI boards with an arizona WM5102 codec ship with either Windows or
Android as factory installed OS.
The ACPI fwnode for the codec on Android boards misses 2 things compared
to the Windows boards (this is hardcoded in the Android board kernels):
1. There is no CLKE ACPI method to enabe the 32 KHz clock the codec needs
for jack-detection.
2. The GPIOs used by the codec are not listed in the fwnode for the codec.
The ACPI tables on x86/ACPI boards shipped with Android being incomplete
happens a lot. The special drivers/platform/x86/x86-android-tablets.c
module contains DMI based per model handling to compensate for this.
This module will enable the 32KHz clock through the pinctrl framework
to fix 1. and it will also register a gpio-lookup table for all GPIOs
needed by the codec + machine driver, including the GPIOs coming from
the codec itself.
Add an arizona_spi_acpi_android_probe() function which waits for the
x86-android-tablets to have set things up before continue with probing
the arizona WM5102 codec.

x86/ACPI boards with an arizona WM5102 codec ship with either Windows or
Android as factory installed OS.
The ACPI fwnode describing the codec differs depending on the factory OS,
and the current arizona_spi_acpi_probe() function is tailored for use
with the Windows board ACPI tables.
Split out the Windows board ACPI tables specific bits into a new
arizona_spi_acpi_windows_probe() function in preparation for also
adding support for the Android board ACPI tables.
