dt-bindings: firmware: arm,scmi: Move arm,scmi-shmem to json schema
Browse files Browse the repository at this point in the history
Move the SRAM and shared memory binding for SCMI into the existing
Generic on-chip SRAM. We just need to update the compatible list and
there-by remove the whole old text format binding for the same.

SRAM and Shared Memory for SCMI
-------------------------------

A small area of SRAM is reserved for SCMI communication between application
processors and SCP.

The properties should follow the generic mmio-sram description found in [4]

Each sub-node represents the reserved area for SCMI.

Required sub-node properties:
- reg : The base offset and size of the reserved area with the SRAM
- compatible : should be "arm,scmi-shmem" for Non-secure SRAM based
shared memory
