Freescale Multi Mode DDR controller (MMDC)
Required properties :
- compatible : should be one of following:
for i.MX6Q/i.MX6DL:
- "fsl,imx6q-mmdc";
for i.MX6QP:
- "fsl,imx6qp-mmdc", "fsl,imx6q-mmdc";
for i.MX6SL:
- "fsl,imx6sl-mmdc", "fsl,imx6q-mmdc";
for i.MX6SLL:
- "fsl,imx6sll-mmdc", "fsl,imx6q-mmdc";
for i.MX6SX:
- "fsl,imx6sx-mmdc", "fsl,imx6q-mmdc";
for i.MX6UL/i.MX6ULL/i.MX6ULZ:
- "fsl,imx6ul-mmdc", "fsl,imx6q-mmdc";
for i.MX7ULP:
- "fsl,imx7ulp-mmdc", "fsl,imx6q-mmdc";
- reg : address and size of MMDC DDR controller registers
Optional properties :
- clocks : the clock provided by the SoC to access the MMDC registers
Example :
mmdc0: memory-controller@21b0000 { /* MMDC0 */
compatible = "fsl,imx6q-mmdc";
reg = <0x021b0000 0x4000>;
clocks = <&clks IMX6QDL_CLK_MMDC_P0_IPG>;
};
mmdc1: memory-controller@21b4000 { /* MMDC1 */
compatible = "fsl,imx6q-mmdc";
reg = <0x021b4000 0x4000>;
status = "disabled";
};
