1* Freescale Enhanced Secure Digital Host Controller (eSDHC)
2
3The Enhanced Secure Digital Host Controller provides an interface
4for MMC, SD, and SDIO types of memory cards.
5
6Required 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.
