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
15
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.yaml
21	   for more details.

23Examples:
24
25- For an OMAP5 SMP system:
26
27mpu {
28    compatible = "ti,omap5-mpu";
29    ti,hwmods = "mpu"
30};
31
32- For an OMAP4 SMP system:
33
34mpu {
35    compatible = "ti,omap4-mpu";
36    ti,hwmods = "mpu";
37};
38
39
40- For an OMAP3 monocore system:
41
42mpu {
43    compatible = "ti,omap3-mpu";
44    ti,hwmods = "mpu";
45};
46
47- For an AM335x system:
48
49mpu {
50	compatible = "ti,omap3-mpu";
51	ti,hwmods = "mpu";
52	pm-sram = <&pm_sram_code
53		   &pm_sram_data>;
54};
