1L4 interconnect bindings
2
3These bindings describe the OMAP SoCs L4 interconnect bus.
4
5Required properties:
6- compatible : Should be "ti,omap2-l4" for OMAP2 family l4 core bus
7	       Should be "ti,omap2-l4-wkup" for OMAP2 family l4 wkup bus
8	       Should be "ti,omap3-l4-core" for OMAP3 family l4 core bus
9	       Should be "ti,omap4-l4-cfg" for OMAP4 family l4 cfg bus
10	       Should be "ti,omap4-l4-per" for OMAP4 family l4 per bus
11	       Should be "ti,omap4-l4-wkup" for OMAP4 family l4 wkup bus
12	       Should be "ti,omap5-l4-cfg" for OMAP5 family l4 cfg bus
13	       Should be "ti,omap5-l4-wkup" for OMAP5 family l4 wkup bus
14	       Should be "ti,dra7-l4-cfg" for DRA7 family l4 cfg bus
15	       Should be "ti,dra7-l4-wkup" for DRA7 family l4 wkup bus
16	       Should be "ti,am3-l4-wkup" for AM33xx family l4 wkup bus
17	       Should be "ti,am4-l4-wkup" for AM43xx family l4 wkup bus
18- ranges : contains the IO map range for the bus
19- reg : registers link agent and interconnect agent and access protection
20- reg-names : "la" for link agent, "ia0" to "ia3" for one to three
21              interconnect agent instances, "ap" for access if it exists
