1 * Freescale Enhanced Secure Digital Host Controller (eSDHC) 2 3 The Enhanced Secure Digital Host Controller provides an interface 4 for MMC, SD, and SDIO types of memory cards. 5 6 Required properties: 7 - compatible : should be 8 "fsl,<chip>-esdhc", "fsl,esdhc" 9 - reg : should contain eSDHC registers location and length. 10 - interrupts : should contain eSDHC interrupt. 11 - interrupt-parent : interrupt source phandle. 12 - clock-frequency : specifies eSDHC base clock frequency. 13 - sdhci,wp-inverted : (optional) specifies that eSDHC controller 14 reports inverted write-protect state; 15 - sdhci,1-bit-only : (optional) specifies that a controller can 16 only handle 1-bit data transfers. 17 - sdhci,auto-cmd12: (optional) specifies that a controller can 18 only handle auto CMD12. 19 20 Example: 21 22 sdhci@2e000 { 23 compatible = "fsl,mpc8378-esdhc", "fsl,esdhc"; 24 reg = <0x2e000 0x1000>; 25 interrupts = <42 0x8>; 26 interrupt-parent = <&ipic>; 27 /* Filled in by U-Boot */ 28 clock-frequency = <0>; 29 };
