If we are faulting on a shadow stage 2 translation, we first walk the
guest hypervisor's stage 2 page table to see if it has a mapping. If
not, we inject a stage 2 page fault to the virtual EL2. Otherwise, we
create a mapping in the shadow stage 2 page table.

Note that we have to deal with two IPAs when we got a shadow stage 2
page fault. One is the address we faulted on, and is in the L2 guest
phys space. The other is from the guest stage-2 page table walk, and is
in the L1 guest phys space.  To differentiate them, we rename variables
so that fault_ipa is used for the former and ipa is used for the latter.

When mapping a page in a shadow stage-2, special care must be taken not
to be more permissive than the guest is.

Add Stage-2 mmu data structures for virtual EL2 and for nested guests.
We don't yet populate shadow Stage-2 page tables, but we now have a
framework for getting to a shadow Stage-2 pgd.

We allocate twice the number of vcpus as Stage-2 mmu structures because
that's sufficient for each vcpu running two translation regimes without
having to flush the Stage-2 page tables.

The Elan eKTH5015M touch controller found on the Lenovo ThinkPad X13s
shares the VCC33 supply with other peripherals that may remain powered
during suspend (e.g. when enabled as wakeup sources).

The reset line is also wired so that it can be left deasserted when the
supply is off.

This is important as it avoids holding the controller in reset for
extended periods of time when it remains powered, which can lead to
increased power consumption, and also avoids leaking current through the
X13s reset circuitry during suspend (and after driver unbind).

Use the new 'no-reset-on-power-off' devicetree property to determine
when reset needs to be asserted on power down.

Notably this also avoids wasting power on machine variants without a
touchscreen for which the driver would otherwise exit probe with reset
asserted.

When the power supply is shared with other peripherals the reset line
can be wired in such a way that it can remain deasserted regardless of
whether the supply is on or not.

This is important as it can be used to avoid holding the controller in
reset for extended periods of time when it remains powered, something
which can lead to increased power consumption. Leaving reset deasserted
also avoids leaking current through the reset circuitry pull-up
resistors.

Add a new 'no-reset-on-power-off' devicetree property which can be used
by the OS to determine when reset needs to be asserted on power down.

Note that this property can also be used when the supply cannot be
turned off by the OS at all.

Judging from the current binding and commit bd3cba00 ("HID: i2c-hid:

appears to be compatible with eKTH6915. Notably the power-on sequence is

The Ilitek ILI2901 touch screen controller was apparently incorrectly
added to the Elan eKTH6915 schema simply because it also has a reset
gpio and is currently managed by the Elan driver in Linux.

The two controllers are not related even if an unfortunate wording in
the commit message adding the Ilitek compatible made it sound like they
were.

Add a dedicated schema for the ILI2901 which does not specify the I2C
address (which is likely 0x41 rather than 0x10 as for other Ilitek touch
controllers) to avoid cluttering the Elan schema with unrelated devices
and to make it easier to find the correct schema when adding further
Ilitek controllers.
