[PATCH] dt-bindings: arm: omap-l3-noc: Convert to DT schema

DORMANTno replies

Subsystem: open firmware and flattened device tree bindings, the rest · Maintainers: Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds

Convert TI L3 NoC binding from text to DT schema format. Older OMAP3
uses the SMX variant which also acts as a bus parent with simple-bus
compatible so child nodes are allowed using patternproperties. Mark
ti,hwmods deprecated as it is no longer needed and only used by older
omap3-l3-smx.

-* TI - L3 Network On Chip (NoC)
-
-This version is an implementation of the generic NoC IP
-provided by Arteris.
-
-Required properties:
-- compatible : Should be "ti,omap3-l3-smx" for OMAP3 family
-               Should be "ti,omap4-l3-noc" for OMAP4 family
-               Should be "ti,omap5-l3-noc" for OMAP5 family
-	       Should be "ti,dra7-l3-noc" for DRA7 family
-               Should be "ti,am4372-l3-noc" for AM43 family
-- reg:	Contains L3 register address range for each noc domain.
-- ti,hwmods: "l3_main_1", ... One hwmod for each noc domain.

-Examples:
-
-ocp {
-	compatible = "ti,omap4-l3-noc", "simple-bus";
-	#address-cells = <1>;
-	#size-cells = <1>;
-	ranges;
-	ti,hwmods = "l3_main_1", "l3_main_2", "l3_main_3";
