When running a 32-bit userspace on a 64-bit kernel, the UI_SET_PHYS
ioctl needs to be treated with special care, as it has the pointer

The length checks on the grant table copy_ops for setting hash key and
hash mapping are checking the local 'len' value which is correct in
the case of the former but not the latter. This was picked up by
static analysis checks.
This patch replaces checks of 'len' with 'copy_op.len' in both cases
to correct the incorrect check, keep the two checks consistent, and to
make it clear what the checks are for.

Since e7f4dc3536a ("mdio: Move allocation of interrupts into core"),
platforms which call fixed_phy_add() before fixed_mdio_bus_init() is
called (for example, because the platform code and the fixed_phy driver
use the same initcall level) crash in fixed_phy_add() since the
->mii_bus is not allocated.
Also since e7f4dc3536a, these interrupts are initalized to polling by
default. The few (old) platforms which directly use fixed_phy_add()
from their platform code all pass PHY_POLL for the irq argument, so we
can keep these platforms not crashing by simply not attempting to set
the irq if PHY_POLL is passed.
Also, even if problems have not been reported on more modern platforms
which used fixed_phy_register() from drivers' probe functions, we return
-EPROBE_DEFER if the MDIO bus is not yet registered so that the probe is
retried later.

The newly added nps irqchip driver causes build warnings on ARM64.
include/soc/nps/common.h: In function 'nps_host_reg_non_cl':
include/soc/nps/common.h:148:9: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
As the driver is only used on ARC, we don't need to see it without
COMPILE_TEST elsewhere, and we can avoid the warnings by only building
on 32-bit architectures even with CONFIG_COMPILE_TEST.

We program RTC time using SET_TIME_WRITE register and read the RTC
current time using CURRENT_TIME register. When we set the time by
writing into SET_TIME_WRITE Register and immediately try to read the
rtc time from CURRENT_TIME register, the previous old value is
returned instead of the new loaded time. This is because RTC takes
nearly 1 sec to update the new loaded value into the CURRENT_TIME
register. This behaviour is expected in our RTC IP.
This patch updates the driver to read the current time from SET_TIME_WRITE
register instead of CURRENT_TIME when rtc time is requested within an 1sec
period after setting the RTC time. Doing so will ensure the correct time is
given to the user.
Since there is a delay of 1sec in updating the CURRENT_TIME we are loading
set time +1sec while programming the SET_TIME_WRITE register, doing this
will give correct time without any delay when read from CURRENT_TIME.

it is expected that the supply for the battery-powered domain
to be switched from the battery (VCC_PSBATT) to (VCC_PSAUX) and
automatically be switched back to battery when VCC_PSAUX voltage
drops below a limit, doing so prevents the logic within

This fix alters the ordering of the IRQ and device registrations in the RTC
driver probe function. This change will apply to the RTC driver that supports
both DA9052 and DA9053 PMICs.
A problem could occur with the existing RTC driver if:
A system is started from a cold boot using the PMIC RTC IRQ to initiate a
power on operation. For instance, if an RTC alarm is used to start a
platform from power off.
The existing driver IRQ is requested before the device has been properly
registered.
i.e.
ret = da9052_request_irq()
comes before
rtc->rtc = devm_rtc_device_register();
In this case, an interrupt exists before the device has been registered and
the IRQ handler can be called immediately: this can happen be before the
memory for rtc->rtc has been allocated. The IRQ handler da9052_rtc_irq()
contains the function call:
rtc_update_irq(rtc->rtc, 1, RTC_IRQF | RTC_AF);
which in turn tries to access the unavailable rtc->rtc.
The fix is to reorder the functions inside the RTC probe. The IRQ is
requested after the RTC device resource has been registered so that
da9052_request_irq() is the last thing to happen.

enabled
If a previously-set alarm was disabled and then triggered, it may still
be pending when a new alarm is configured.
Then, if the alarm is enabled before the pending alarm is cleared, then
an interrupt is immediately raised.
Unfortunately, when the alarm is cleared and enabled during the same I²C
block write, the chip (at least the DS1339 I have) considers that the
alarm is enabled before it is cleared, and raises an interrupt.
This patch ensures that the pending alarm is cleared before the alarm is
enabled.
