[PATCH v2 1/8] dt-bindings: firmware: arm, scpi: Move arm, scp-shmem to json schema

From: Sudeep Holla <hidden>
Date: 2021-06-01 22:49:14
Also in: linux-devicetree
Subsystem: open firmware and flattened device tree bindings, the rest · Maintainers: Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds

Move the SRAM and shared memory binding for SCPI 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 SCPI
--------------------------------
-
-A small area of SRAM is reserved for SCPI communication between application
-processors and SCP.
-
-The properties should follow the generic mmio-sram description found in [3]
-
-Each sub-node represents the reserved area for SCPI.
-
-Required sub-node properties:
-- reg : The base offset and size of the reserved area with the SRAM
-- compatible : should be "arm,scp-shmem" for Non-secure SRAM based
-	       shared memory
-
 Sensor bindings for the sensors based on SCPI Message Protocol
 --------------------------------------------------------------
 SCPI provides an API to access the various sensors on the SoC.
