Subject: [PATCH 01/12] dt-bindings: bus: ti-sysc: Add support for PRUSS SYSC type

From: Roger Quadros <rogerq@...com>

The PRUSS module has a SYSCFG which is unique. The SYSCFG
has two additional unique fields called STANDBY_INIT and
SUB_MWAIT in addition to regular IDLE_MODE and STANDBY_MODE
fields. Add the bindings for this new sysc type.
