ACPI 6.0 introduced LPI(Low Power Idle) states that provides an alternate
method to describe processor idle states.
LPI extensions leverages the processor container device(again introduced
in ACPI 6.0) allowing to express which parts of the system are affected
by a given LPI state. It defines the local power states for each node
in a hierarchical processor topology. The OSPM can use _LPI object to
select a local power state for each level of processor hierarchy in the
system.
This patch adds LPI support on Juno.

As for patch #1, I cannot review or test this.
This currently can't be tested with mainline kernel yet.
The patches to support this are still under review
