1 * Atmel High Speed MultiMedia Card Interface
3 This controller on atmel products provides an interface for MMC, SD and SDIO
6 This file documents differences between the core properties described
7 by mmc.txt and the properties used by the atmel-mci driver.
12 - compatible: should be "atmel,hsmci"
13 - #address-cells: should be one. The cell is the slot id.
14 - #size-cells: should be zero.
15 - at least one slot node
17 The node contains child nodes for each slot that the platform uses
22 compatible = "atmel,hsmci";
23 reg = <0xf0008000 0x600>;
28 [ child node definitions...]
34 - reg: should contain the slot id.
35 - bus-width: number of data lines connected to the controller
38 - cd-gpios: specify GPIOs for card detection
39 - cd-inverted: invert the value of external card detect gpio line
40 - wp-gpios: specify GPIOs for write protection
47 cd-gpios = <&pioD 15 0>
51 Example full MCI node:
53 compatible = "atmel,hsmci";
54 reg = <0xf0008000 0x600>;
61 cd-gpios = <&pioD 15 0>
