From: Dave Gerlach <[email protected]>
Add documentation for the lpm region which tells the ti-sci driver where
to load the FS Stub low power mode firmware and also the firmware-name
which tells the driver which binary to load. Both of these are optional
for normal system operation but required to enabled suspend-to-mem usage
of Deep Sleep state.
