ARM: dts: omap24xx: add minimal l4 bus layout with control module support
This patch creates an l4 / l4-wkup interconnects for omap2420 / omap2430 SoCs, and moves some of the generic peripherals under it. System control module nodes are moved under this new interconnect also, and the SCM clock layout is changed to use the new SCM node as the clock provider. Signed-off-by: Tero Kristo <t-kristo@ti.com>

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
|
||||
- ranges : contains the IO map range for the bus
|
||||
|
||||
Examples:
|
||||
|
||||
l4: l4@48000000 {
|
||||
compatible "ti,omap2-l4", "simple-bus";
|
||||
