OMAP Dynamic Memory Manager (DMM) bindings
|
|
|
|
The dynamic memory manager (DMM) is a module located immediately in front of the
|
|
SDRAM controllers (called EMIFs on OMAP). DMM manages various aspects of memory
|
|
accesses such as priority generation amongst initiators, configuration of SDRAM
|
|
interleaving, optimizing transfer of 2D block objects, and provide MMU-like page
|
|
translation for initiators which need contiguous dma bus addresses.
|
|
|
|
Required properties:
|
|
- compatible: Should contain "ti,omap4-dmm" for OMAP4 family
|
|
Should contain "ti,omap5-dmm" for OMAP5 and DRA7x family
|
|
- reg: Contains DMM register address range (base address and length)
|
|
- interrupts: Should contain an interrupt-specifier for DMM_IRQ.
|
|
- ti,hwmods: Name of the hwmod associated to DMM, which is typically "dmm"
|
|
|
|
Example:
|
|
|
|
dmm@4e000000 {
|
|
compatible = "ti,omap4-dmm";
|
|
reg = <0x4e000000 0x800>;
|
|
ti,hwmods = "dmm";
|
|
};
