-* Atmel High Speed MultiMedia Card Interface
-
-This controller on atmel products provides an interface for MMC, SD and SDIO
-types of memory cards.
-
-This file documents differences between the core properties described
-by mmc.txt and the properties used by the atmel-mci driver.
-
-1) MCI node
-
-Required properties:
-- compatible: should be "atmel,hsmci"
-- #address-cells: should be one. The cell is the slot id.
-- #size-cells: should be zero.
-- at least one slot node
-- clock-names: tuple listing input clock names.
- Required elements: "mci_clk"
-- clocks: phandles to input clocks.
-
-The node contains child nodes for each slot that the platform uses
-
-Example MCI node:
-
-mmc0: mmc@f0008000 {
- compatible = "atmel,hsmci";
- reg = <0xf0008000 0x600>;
- interrupts = <12 4>;
- #address-cells = <1>;
- #size-cells = <0>;
- clock-names = "mci_clk";
- clocks = <&mci0_clk>;
-
- [ child node definitions...]
-};
-
-2) slot nodes
-
-Required properties:
-- reg: should contain the slot id.
-- bus-width: number of data lines connected to the controller
-
-Optional properties:
-- cd-gpios: specify GPIOs for card detection
-- cd-inverted: invert the value of external card detect gpio line
-- wp-gpios: specify GPIOs for write protection
-
-Example slot node:
-
-slot@0 {
- reg = <0>;
- bus-width = <4>;
- cd-gpios = <&pioD 15 0>
- cd-inverted;
-};
-
-Example full MCI node:
-mmc0: mmc@f0008000 {
- compatible = "atmel,hsmci";
- reg = <0xf0008000 0x600>;
- interrupts = <12 4>;
- #address-cells = <1>;
- #size-cells = <0>;
- slot@0 {
- reg = <0>;
- bus-width = <4>;
- cd-gpios = <&pioD 15 0>
- cd-inverted;
- };
- slot@1 {
- reg = <1>;
- bus-width = <4>;
- };
-};
Convert atmel,hsmci documentation to yaml format. The new file will inherit from mmc-controller.yaml.
