1 * TI - MPU (Main Processor Unit) subsystem
2
3 The MPU subsystem contain one or several ARM cores
4 depending of the version.
5 The MPU contain CPUs, GIC, L2 cache and a local PRCM.
6
7 Required 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
13 Optional properties:
14 - sram: Phandle to the ocmcram node
15
16 am335x 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.

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