Subject[PATCH 1/6] dt-bindings: ti,sci: Add ti,ctx-memory-region property
Date
Add documentation for the ti,ctx-memory-region property which is a
phandle to a reserved-memory carveout to be used by the ti_sci driver
storage of low power mode memory context. This is optional for normal
system operation but required to enabled suspend-to-mem usage of Deep
Sleep state.
