1 * TI Highspeed MMC host controller for OMAP
3 The Highspeed MMC Host Controller on TI OMAP family
4 provides an interface for MMC, SD, and SDIO types of memory cards.
8 Should be "ti,omap2-hsmmc", for OMAP2 controllers
9 Should be "ti,omap3-hsmmc", for OMAP3 controllers
10 Should be "ti,omap4-hsmmc", for OMAP4 controllers
11 - ti,hwmods: Must be "mmc<n>", n is controller instance starting 1
12 - reg : should contain hsmmc registers location and length
15 ti,dual-volt: boolean, supports dual voltage cards
16 <supply-name>-supply: phandle to the regulator device tree node
17 "supply-name" examples are "vmmc", "vmmc_aux" etc
18 ti,bus-width: Number of data lines, default assumed is 1 if the property is missing.
19 cd-gpios: GPIOs for card detection
20 wp-gpios: GPIOs for write protection
21 ti,non-removable: non-removable slot (like eMMC)
22 ti,needs-special-reset: Requires a special softreset sequence
25 mmc1: mmc@0x4809c000 {
26 compatible = "ti,omap4-hsmmc";
27 reg = <0x4809c000 0x400>;
31 vmmc-supply = <&vmmc>; /* phandle to regulator node */
