2019-08-12dt-bindings: arm: Extend SCMI to support new reset protocolSudeep Holla
SCMIv2.0 adds a new Reset Management Protocol to manage various reset states a given device or domain can enter. Extend the existing SCMI bindings to add reset protocol support by re-using the reset bindings for both reset providers and consumers.

2019-06-12dt-bindings: arm: fix the document ID for SCMI protocol documentationVolodymyr Babchuk
arm,scmi.txt used the wrong document identifier. "ARM DUI 0922B" is the "ARM Compute Subsystem SCP, Message Interface Protocols". What we need is the ARM DEN 0056A - "ARM System Control and Management Interface Platform Design Document".

Interface(SCMI) protocol This patch adds devicetree binding for System Control and Management Interface (SCMI) Message Protocol used between the Application Cores(AP) and the System Control Processor(SCP). The MHU peripheral provides a mechanism for inter-processor communication between SCP's M3 processor and AP. SCP offers control and management of the core/cluster power states, various power domain DVFS including the core/cluster, certain system clocks configuration, thermal sensors and many others. SCMI protocol is developed as better replacement to the existing SCPI which is not flexible and easily extensible.
