1 * Freescale Enhanced Secure Digital Host Controller (eSDHC)
3 The Enhanced Secure Digital Host Controller provides an interface
4 for MMC, SD, and SDIO types of memory cards.
6 This file documents differences between the core properties described
7 by mmc.txt and the properties used by the sdhci-esdhc driver.
10 - interrupt-parent : interrupt source phandle.
11 - clock-frequency : specifies eSDHC base clock frequency.
14 - sdhci,wp-inverted : specifies that eSDHC controller reports
15 inverted write-protect state; New devices should use the generic
16 "wp-inverted" property.
17 - sdhci,1-bit-only : specifies that a controller can only handle
18 1-bit data transfers. New devices should use the generic
19 "bus-width = <1>" property.
20 - sdhci,auto-cmd12: specifies that a controller can only handle auto
22 - voltage-ranges : two cells are required, first cell specifies minimum
23 slot voltage (mV), second cell specifies maximum slot voltage (mV).
24 Several ranges could be specified.
