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"; |
|
};
