This patch creates an l4_core interconnect for OMAP3, 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 renamed SCM node as the clock provider.

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.
