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.
6 This file documents differences between the core properties described
7 by mmc.txt and the properties used by the omap_hsmmc driver.
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
17 ti,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
20 ti,non-removable: non-removable slot (like eMMC)
21 ti,needs-special-reset: Requires a special softreset sequence
22 ti,needs-special-hs-handling: HSMMC IP needs special setting for handling High Speed
