-Allwinnner SoC SRAM controllers
------------------------------------------------------
-
-The SRAM controller found on most Allwinner devices is represented by
-a regular node for the SRAM controller itself, with sub-nodes
-reprensenting the SRAM handled by the SRAM controller.
-
-Controller Node
----------------
-
-Required properties:
-- compatible : should be:
-    - "allwinner,sun4i-a10-sram-controller" (deprecated)
-    - "allwinner,sun4i-a10-system-control"
-    - "allwinner,sun5i-a13-system-control"
-    - "allwinner,sun7i-a20-system-control", "allwinner,sun4i-a10-system-control"
-    - "allwinner,sun8i-a23-system-control"
-    - "allwinner,sun8i-h3-system-control"
-    - "allwinner,sun50i-a64-sram-controller" (deprecated)
-    - "allwinner,sun50i-a64-system-control"
-    - "allwinner,sun50i-h5-system-control"
-    - "allwinner,sun50i-h6-system-control", "allwinner,sun50i-a64-system-control"

-SRAM nodes
-----------
-
-Each SRAM is described using the mmio-sram bindings documented in
-Documentation/devicetree/bindings/sram/sram.txt
-
-Each SRAM will have SRAM sections that are going to be handled by the
-SRAM controller as subnodes. These sections are represented following
-once again the representation described in the mmio-sram binding.
-
-The valid sections compatible for A10 are:
-    - allwinner,sun4i-a10-sram-a3-a4
-    - allwinner,sun4i-a10-sram-c1
-    - allwinner,sun4i-a10-sram-d
-
-The valid sections compatible for A13 are:
-    - allwinner,sun5i-a13-sram-a3-a4, allwinner,sun4i-a10-sram-a3-a4
-    - allwinner,sun5i-a13-sram-c1, allwinner,sun4i-a10-sram-c1
-    - allwinner,sun5i-a13-sram-d, allwinner,sun4i-a10-sram-d
-
-The valid sections compatible for A20 are:
-    - allwinner,sun7i-a20-sram-a3-a4, allwinner,sun4i-a10-sram-a3-a4
-    - allwinner,sun7i-a20-sram-c1, allwinner,sun4i-a10-sram-c1
-    - allwinner,sun7i-a20-sram-d, allwinner,sun4i-a10-sram-d
-
-The valid sections compatible for A23/A33 are:
-    - allwinner,sun8i-a23-sram-c1, allwinner,sun4i-a10-sram-c1
-
-The valid sections compatible for H3 are:
-    - allwinner,sun8i-h3-sram-c1, allwinner,sun4i-a10-sram-c1
-
-The valid sections compatible for A64 are:
-    - allwinner,sun50i-a64-sram-c
-    - allwinner,sun50i-a64-sram-c1, allwinner,sun4i-a10-sram-c1
-
-The valid sections compatible for H5 are:
-    - allwinner,sun50i-h5-sram-c1, allwinner,sun4i-a10-sram-c1
-
-The valid sections compatible for H6 are:
-    - allwinner,sun50i-h6-sram-c, allwinner,sun50i-a64-sram-c
-    - allwinner,sun50i-h6-sram-c1, allwinner,sun4i-a10-sram-c1
-
-The valid sections compatible for F1C100s are:
-    - allwinner,suniv-f1c100s-sram-d, allwinner,sun4i-a10-sram-d
-
-Devices using SRAM sections
----------------------------
-
-Some devices need to request to the SRAM controller to map an SRAM for
-their exclusive use.
-
-The relationship between such a device and an SRAM section is
-expressed through the allwinner,sram property, that will take a
-phandle and an argument.
-
-This valid values for this argument are:
-  - 0: CPU
-  - 1: Device
-
