This patch creates the l4_cfg and l4_wkup interconnects for OMAP4, and moves some of the generic peripherals under it. System control module support is added to the device tree also, and the existing SCM related functionality is moved under it.

OMAP PRCM bindings

|
Power Reset and Clock Manager lists the device clocks and clockdomains under
|
|
a DT hierarchy. Each TI SoC can have multiple PRCM entities listed for it,
|
|
each describing one module and the clock hierarchy under it. see [1] for
|
|
documentation about the individual clock/clockdomain nodes.
