1OMAP Dynamic Memory Manager (DMM) bindings 2 3The dynamic memory manager (DMM) is a module located immediately in front of the 4SDRAM controllers (called EMIFs on OMAP). DMM manages various aspects of memory 5accesses such as priority generation amongst initiators, configuration of SDRAM 6interleaving, optimizing transfer of 2D block objects, and provide MMU-like page 7translation for initiators which need contiguous dma bus addresses. 8 9Required 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 16Example: 17 18dmm@4e000000 { 19 compatible = "ti,omap4-dmm"; 20 reg = <0x4e000000 0x800>; 21 ti,hwmods = "dmm"; 22};
