1Freescale Multi Mode DDR controller (MMDC)
2
3Required properties :
4- compatible : should be one of following:
5 for i.MX6Q/i.MX6DL:
6 - "fsl,imx6q-mmdc";
7 for i.MX6QP:
8 - "fsl,imx6qp-mmdc", "fsl,imx6q-mmdc";
9 for i.MX6SL:
10 - "fsl,imx6sl-mmdc", "fsl,imx6q-mmdc";
11 for i.MX6SLL:
12 - "fsl,imx6sll-mmdc", "fsl,imx6q-mmdc";
13 for i.MX6SX:
14 - "fsl,imx6sx-mmdc", "fsl,imx6q-mmdc";
15 for i.MX6UL/i.MX6ULL/i.MX6ULZ:
16 - "fsl,imx6ul-mmdc", "fsl,imx6q-mmdc";
17 for i.MX7ULP:
18 - "fsl,imx7ulp-mmdc", "fsl,imx6q-mmdc";
19- reg : address and size of MMDC DDR controller registers
20
21Optional properties :
22- clocks : the clock provided by the SoC to access the MMDC registers
23
24Example :
25 mmdc0: memory-controller@21b0000 { /* MMDC0 */
26 compatible = "fsl,imx6q-mmdc";
27 reg = <0x021b0000 0x4000>;
28 clocks = <&clks IMX6QDL_CLK_MMDC_P0_IPG>;
29 };
30
31 mmdc1: memory-controller@21b4000 { /* MMDC1 */
32 compatible = "fsl,imx6q-mmdc";
33 reg = <0x021b4000 0x4000>;
34 status = "disabled";
35 };
