More devices are cropping up requiring only Regmap initialisation and
child registration functionality.  We currently only support that if
all required devices are represented by their own Device Tree nodes
complete with compatible strings.

However, not everyone is happy with adding empty nodes that provide no
additional device information into the Device Tree.

Rather than have a plethora of mostly empty, function-less drivers in
MFD, we'll support those simple cases in here instead via MFD cells.

The PRCMU driver defines this as a DT node but there are no bindings
for it and it needs no data from the device tree. Just spawn the
device directly in the same way as the watchdog.

Name it "db8500-cpuidle" since there are no ambitions to support any
more SoCs than this one.

This rids this annoying boot message:

However I think the device still spawns and work just fine, despite
not finding a device tree node.

The power-supply framework has the notion of one power-supply device
being supplied by another. A typical example of this is a charger
charging a battery.

A tablet getting plugged in to charge (or plugged out) only results in
events seen by the axp288_charger device / MFD cell. Which means that
a change udev-event only gets send for the charger power-supply class
device, not for the battery (the axp288_fuel_gauge device).

The axp288_fuel_gauge does have an external_power_change'd callback
which will generate a change udev-event when called. But before this
commit this never got called because the power-supply core only calls
this when a power-supply class device's supplier changes and the
supplier link from axp288_charger to axp288_fuel_gauge was missing.

Add a "supplied-from" property to axp288_fuel_gauge cell, pointing
to the "axp288_charger" power-supply class device, so that the
axp288_fuel_gauge's external_power_change'd callback gets called on
axp288_charger state changes.

On Cherry Trail devices with an AXP288 PMIC the external SD-card slot
used the AXP's DLDO2 as card-voltage and either DLDO3 or GPIO1LDO
(GPIO1 pin in low noise LDO mode) as signal-voltage.

These regulators are turned on/off and in case of the signal-voltage
also have their output-voltage changed by the _PS0 and _PS3 power-
management ACPI methods on the MMC-controllers ACPI fwnode as well as
by the _DSM ACPI method for changing the signal voltage.

The AML code implementing these methods is directly accessing the
PMIC through ACPI I2C OpRegion accesses, instead of using the special
PMIC OpRegion handled by drivers/acpi/pmic/intel_pmic_xpower.c .

This means that the contents of the involved PMIC registers can change
without the change being made through the regmap interface, so regmap
should not cache the contents of these registers.

Mark the regulator power on/off, the regulator voltage control and the
GPIO1 control registers as volatile, to avoid regmap caching them.

Specifically this fixes an issue on some models where the i915 driver
toggles another LDO using the same on/off register on/off through
MIPI sequences (through intel_soc_pmic_exec_mipi_pmic_seq_element())
which then writes back a cached on/off register-value where the
card-voltage is off causing the external sdcard slot to stop working
when the screen goes blank, or comes back on again.

The regulator register-range now marked volatile also includes the
buck regulator control registers. This is done on purpose these are
normally not touched by the AML code, but they are updated directly
by the SoC's PUNIT which means that they may also change without going
through regmap.

Note the AXP288 PMIC is only used on Bay- and Cherry-Trail platforms,
so even though this is an ACPI specific problem there is no need to
make the new volatile ranges conditional since these platforms always
use ACPI.

The kernel recovers in due course from missing Mlocked pages: but there
was no point in calling page_mlock() (formerly known as
try_to_munlock()) on a THP, because nothing got done even when it was
found to be mapped in another VM_LOCKED vma.

It's true that we need to be careful: Mlocked accounting of pte-mapped
THPs is too difficult (so consistently avoided); but Mlocked accounting
of only-pmd-mapped THPs is supposed to work, even when multiple mappings
are mlocked and munlocked or munmapped.  Refine the tests.

There is already a VM_BUG_ON_PAGE(PageDoubleMap) in page_mlock(), so
page_mlock_one() does not even have to worry about that complication.

(I said the kernel recovers: but would page reclaim be likely to split
THP before rediscovering that it's VM_LOCKED? I've not followed that up)
