ARM: ux500: pass parent pointer to each platform device

This patch provides a means for any device within ux500
platform code to allocate its own parent. This is particularly
prudent with the introduction of /sys/devices/socX, as a
device can now proclaim to be integral part of an SoC, rather
than a more generic platform device. Latter patches make good
use of this functionality.

So let us focus on supporting the silicon that will be used and
delete this to get a clear overview.

around in this patch set we postpone that by simply deactivating
it for the time being.

This is a snapshot of the current PRCMU firmware API as it looks
right now. The PRCMU firmware is still subject to change. This
also updates the CPUfreq driver to a newer version that will
utilize the new API.

mfd: db8500-prcmu: Support U8420-sysclk firmware

There is a distinct version of the Ux500 U8420 variant
with "sysclk", as can be seen from the vendor code that
didn't make it upstream, this firmware lacks the
ULPPLL (ultra-low power phase locked loop) which in
effect means that the timer clock is instead wired to
the 32768 Hz always-on clock.

This has some repercussions when enabling the timer
clock as the code as it stands will disable the timer
clock on these platforms (lacking the so-called
"doze mode") and obtaining the wrong rate of the timer
clock.

The timer frequency is of course needed very early in
the boot, and as a consequence, we need to shuffle
around the early PRCMU init code: whereas in the past
we did not need to look up the PRCMU firmware version
in the early init, but now we need to know the version
before the core system timers are registered so we
restructure the platform callbacks to the PRCMU so as
not to take any arguments and instead look up the
resources it needs directly from the device tree
when initializing.

As we do not yet support any platforms using this
firmware it is not a regression, but as PostmarketOS
is starting to support products with this firmware we
need to fix this up.

The low rate of 32kHz also makes the MTU timer unsuitable
as delay timer but this needs to be fixed in a separate
patch.

The PRCMU devices are getting populated from the MFD

have an early quirk for the things that need to happen
really early and the PRCMU timer that need to be registered
really early will find its own node just fine as the
timer/clocksource subsystem looks through the whole device
tree for compatible nodes.

ARM: ux500: Fix PMU IRQ regression

Commit 2b05f6ae1ee5 ("ARM: ux500: remove PMU IRQ bouncer")
deleted some code to bounce and work around the weird PMU
IRQs in the DB8500 ASIC, but did a semantic mistake:
since the auxdata was now unused, the call to
of_platform_populate() was removed, but this does not
work: the default platform population will only kick in
if .init_machine() is assigned NULL, and since the U8540
was still using the callback that was not the case.

Fix this by reinstating the call to of_platform_populate(),
but pass NULL as auxdata.

ARM: ux500: Fix regression while init PM domains

The commit afece3ab9a36 ("PM / Domains: Add time accounting to various
genpd states") causes a boot regression for ux500.

The problem occurs when the ux500 machine code calls pm_genpd_init(), which
since the above change triggers a call to ktime_get(). More precisely,
because ux500 initializes PM domains in the init_IRQ() phase of the boot,
timekeeping has not yet been initialized.

Fix the problem by moving the initialization of the PM domains to after
timekeeping has been initialized.
