| 2 | |
| 3 | The dynamic memory manager (DMM) is a module located immediately in front of the |
| 4 | SDRAM controllers (called EMIFs on OMAP). DMM manages various aspects of memory |
| 5 | accesses such as priority generation amongst initiators, configuration of SDRAM |
| 6 | interleaving, optimizing transfer of 2D block objects, and provide MMU-like page |
| 7 | translation for initiators which need contiguous dma bus addresses. |
| 8 | |
| 9 | Required properties: |
| 10 | - compatible: Should contain "ti,omap4-dmm" for OMAP4 family |
| 11 | Should contain "ti,omap5-dmm" for OMAP5 and DRA7x family |
| 12 | - reg: Contains DMM register address range (base address and length) |
| 13 | - interrupts: Should contain an interrupt-specifier for DMM_IRQ. |
| 14 | - ti,hwmods: Name of the hwmod associated to DMM, which is typically "dmm" |
| 15 | |
| 16 | Example: |
| 17 | |
| 18 | dmm@4e000000 { |
| 19 | compatible = "ti,omap4-dmm"; |
| 20 | reg = <0x4e000000 0x800>; |
| 21 | ti,hwmods = "dmm"; |
| 22 | }; |
