    dt-bindings: mailbox: Add support for secure proxy threads · 0f23a179

    Secure Proxy is another communication scheme in Texas Instrument's
    devices intended to provide an unique communication path from various
    processors in the System on Chip(SoC) to a central System Controller.
    
    Secure proxy is, in effect, an evolution of current generation Message
    Manager hardware block found in K2G devices. However the following
    changes have taken place:
    
    Secure Proxy instance exposes "threads" or "proxies" which is
    primary representation of "a" communication channel. Each thread is
    preconfigured by System controller configuration based on SoC usage
    requirements. Secure proxy by itself represents a single "queue" of
    communication but allows the proxies to be independently operated.
    
    Each Secure proxy thread can uniquely have their own error and threshold
    interrupts allowing for more fine control of IRQ handling.
    
    Provide an hardware description of the same for device tree
    representation.
