1* TI OMAP SDHCI Controller 2 3Refer to mmc.txt for standard MMC bindings. 4 5For UHS devices which require tuning, the device tree should have a "cpu_thermal" node which maps to the appropriate thermal zone. This is used to get the temperature of the zone during tuning. 6 7Required properties: 8- compatible: Should be "ti,omap2430-sdhci" for omap2430 controllers 9 Should be "ti,omap3-sdhci" for omap3 controllers 10 Should be "ti,omap4-sdhci" for omap4 and ti81 controllers 11 Should be "ti,omap5-sdhci" for omap5 controllers 12 Should be "ti,dra7-sdhci" for DRA7 and DRA72 controllers 13 Should be "ti,k2g-sdhci" for K2G 14 Should be "ti,am335-sdhci" for am335x controllers 15 Should be "ti,am437-sdhci" for am437x controllers 16- ti,hwmods: Must be "mmc<n>", <n> is controller instance starting 1 17 (Not required for K2G). 18- pinctrl-names: Should be subset of "default", "hs", "sdr12", "sdr25", "sdr50", 19 "ddr50-rev11", "sdr104-rev11", "ddr50", "sdr104", 20 "ddr_1_8v-rev11", "ddr_1_8v" or "ddr_3_3v", "hs200_1_8v-rev11", 21 "hs200_1_8v", 22- pinctrl-<n> : Pinctrl states as described in bindings/pinctrl/pinctrl-bindings.txt 23 24Optional properties: 25- dmas: List of DMA specifiers with the controller specific format as described 26 in the generic DMA client binding. A tx and rx specifier is required. 27- dma-names: List of DMA request names. These strings correspond 1:1 with the 28 DMA specifiers listed in dmas. The string naming is to be "tx" 29 and "rx" for TX and RX DMA requests, respectively. 30 31Deprecated properties: 32- ti,non-removable: Compatible with the generic non-removable property 33 34Example: 35 mmc1: mmc@4809c000 { 36 compatible = "ti,dra7-sdhci"; 37 reg = <0x4809c000 0x400>; 38 ti,hwmods = "mmc1"; 39 bus-width = <4>; 40 vmmc-supply = <&vmmc>; /* phandle to regulator node */ 41 dmas = <&sdma 61 &sdma 62>; 42 dma-names = "tx", "rx"; 43 };
