6This file documents differences between the core properties described
7by mmc.txt and the properties used by the omap_hsmmc driver.
8
9Required properties:
10- compatible:
11 Should be "ti,omap2-hsmmc", for OMAP2 controllers
12 Should be "ti,omap3-hsmmc", for OMAP3 controllers
13 Should be "ti,omap4-hsmmc", for OMAP4 controllers
14- ti,hwmods: Must be "mmc<n>", n is controller instance starting 1
15
16Optional properties:
17ti,dual-volt: boolean, supports dual voltage cards
18<supply-name>-supply: phandle to the regulator device tree node
19"supply-name" examples are "vmmc", "vmmc_aux" etc
20ti,non-removable: non-removable slot (like eMMC)
21ti,needs-special-reset: Requires a special softreset sequence
22ti,needs-special-hs-handling: HSMMC IP needs special setting for handling High Speed

24Example:
25	mmc1: mmc@0x4809c000 {
26		compatible = "ti,omap4-hsmmc";
27		reg = <0x4809c000 0x400>;
28		ti,hwmods = "mmc1";
29		ti,dual-volt;
30		bus-width = <4>;
31		vmmc-supply = <&vmmc>; /* phandle to regulator node */
32		ti,non-removable;
33	};
