1* TI - MPU (Main Processor Unit) subsystem
2
3The MPU subsystem contain one or several ARM cores
4depending of the version.
5The MPU contain CPUs, GIC, L2 cache and a local PRCM.
6
7Required properties:
8- compatible : Should be "ti,omap3-mpu" for OMAP3
9 Should be "ti,omap4-mpu" for OMAP4
10 Should be "ti,omap5-mpu" for OMAP5
11- ti,hwmods: "mpu"
12
13Optional properties:
14- sram: Phandle to the ocmcram node

16am335x and am437x only:
17- pm-sram: Phandles to ocmcram nodes to be used for power management.
18 First should be type 'protect-exec' for the driver to use to copy
19 and run PM functions, second should be regular pool to be used for
20 data region for code. See Documentation/devicetree/bindings/sram/sram.txt
21 for more details.
