80 Definition: a phandle reference to a syscon representing TCSR followed
81 by the three offsets within syscon for q6, modem and nc
85 The Hexagon node must contain two subnodes, named "mba" and "mpss" representing
86 the memory regions used by the Hexagon firmware. Each sub-node must contain:
91 Definition: reference to the reserved-memory for the region
