Use "hpd" method to notify external display module about
cable status change and "notify" as an acknowledgment to
power on or off. This makes hpd method as a blocking
call completed by notify call.

On ARM systems the cache topology cannot be probed at runtime, in
particular, it is impossible to probe which CPUs share a given cache
level. Power management software requires this knowledge to implement
optimized power down sequences, hence this patch adds a document that
defines the DT cache bindings for ARM systems. The bindings are compliant
with ePAPR (PowerPC bindings), even though most of the cache nodes
properties requirements are overriden, because caches geometry for
architected caches is probeable on ARM systems. This patch also adds
properties that are specific to ARM architected caches to the existing ones
defined in the ePAPR v1.1, as bindings extensions.

For hyp_assign calls, dest_vm_and_perm_info wrongly
defines ctx as u32 * type, while TZ expects it as u64.
This creates an inconsistency on 32bit system. Fix it.

The global mutex of 'gdp_mutex' is used to serialize creating/querying
glue dir and its cleanup. Turns out it isn't a perfect way because
part(kobj_kset_leave()) of the actual cleanup action() is done inside
the release handler of the glue dir kobject. That means gdp_mutex has
to be held before releasing the last reference count of the glue dir
kobject.
This patch moves glue dir's cleanup after kobject_del() in device_del()
for avoiding the race.

Avoid calling bus clear pdata when bus manager is de-initialized as
this is a redundant call. This is taken care by the base device
driver release_node function.

If "core" memory resource is not specified, the driver could end up
dereferencing a null pointer.
Fix this by returning -EINVAL when core resource is missing.

as well on stop.

Currently, only one partial update ROI is supported, with
multiple partial update feature the driver would support
two partial update ROIs. The commit structs left_roi and
right_roi along with a special flag are used to pass the
two ROIs to the driver to minimize interface changes. MDP
will add the two ROIs which is width aligned and configures
the LMs accordingly and updates the panel info with the
dual roi configs, so DSI is aware of multiple PU config and
send DCS commands accordingly.
