Convert the Texas Instruments OMAP L4 interconnect bus bindings
to DT schema.
During the conversion, several updates were made:
- Defined the compatible property as an array to require
the TI-specific string first, followed by either 'simple-bus' or
'simple-pm-bus'.
- Added a 'select' block to ensure this schema is only
applied to TI-specific nodes, preventing duplicate
schema warnings against the core simple-pm-bus.yaml.
- Made 'reg' and 'reg-names' optional.

-L4 interconnect bindings

-These bindings describe the OMAP SoCs L4 interconnect bus.

-Required properties:
-- compatible : Should be "ti,omap2-l4" for OMAP2 family l4 core bus
- Should be "ti,omap2-l4-wkup" for OMAP2 family l4 wkup bus
- Should be "ti,omap3-l4-core" for OMAP3 family l4 core bus
- Should be "ti,omap4-l4-cfg" for OMAP4 family l4 cfg bus
- Should be "ti,omap4-l4-per" for OMAP4 family l4 per bus
- Should be "ti,omap4-l4-wkup" for OMAP4 family l4 wkup bus
- Should be "ti,omap5-l4-cfg" for OMAP5 family l4 cfg bus
- Should be "ti,omap5-l4-wkup" for OMAP5 family l4 wkup bus
- Should be "ti,dra7-l4-cfg" for DRA7 family l4 cfg bus
- Should be "ti,dra7-l4-wkup" for DRA7 family l4 wkup bus
- Should be "ti,am3-l4-wkup" for AM33xx family l4 wkup bus
- Should be "ti,am4-l4-wkup" for AM43xx family l4 wkup bus
-- ranges : contains the IO map range for the bus
-- reg : registers link agent and interconnect agent and access protection
-- reg-names : "la" for link agent, "ia0" to "ia3" for one to three
- interconnect agent instances, "ap" for access if it exists
-
-Examples:
-
-l4: interconnect@48000000 {
- compatible "ti,omap4-l4-per", "simple-bus";
- reg = <0x48000000 0x800>,

A different dependency should be noted in *this* patch. If you already ran 'make dt_binding_check' and didn't see the above error(s), then make sure 'yamllint' is installed and dt-schema is up to date: pip3 install dtschema --upgrade Please check and re-submit after running the above command yourself. Note that DT_SCHEMA_FILES can be set to your schema file to speed up checking your schema. However, it must be unset to test all examples with your schema.
