Kernel-4.18.0-80.el8_mpu

• TI - MPU (Main Processor Unit) subsystem

The MPU subsystem contain one or several ARM cores
depending of the version.
The MPU contain CPUs, GIC, L2 cache and a local PRCM.

Required properties:

• compatible : Should be “ti,omap3-mpu” for OMAP3

           Should be "ti,omap4-mpu" for OMAP4
       Should be "ti,omap5-mpu" for OMAP5
  

• ti,hwmods: “mpu”

Optional properties:

• sram: Phandle to the ocmcram node

am335x and am437x only:

• pm-sram: Phandles to ocmcram nodes to be used for power management.

   First should be type 'protect-exec' for the driver to use to copy
   and run PM functions, second should be regular pool to be used for
   data region for code. See Documentation/devicetree/bindings/sram/sram.txt
   for more details.
  

Examples:

• For an OMAP5 SMP system:

mpu {
compatible = “ti,omap5-mpu”;
ti,hwmods = “mpu”
};

• For an OMAP4 SMP system:

mpu {
compatible = “ti,omap4-mpu”;
ti,hwmods = “mpu”;
};

• For an OMAP3 monocore system:

mpu {
compatible = “ti,omap3-mpu”;
ti,hwmods = “mpu”;
};

• For an AM335x system:

mpu {
compatible = “ti,omap3-mpu”;
ti,hwmods = “mpu”;
pm-sram = <&pm_sram_code
&pm_sram_data>;
};
