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,dra7-sdhci" for DRA7 and DRA72 controllers 9 Should be "ti,k2g-sdhci" for K2G 10 Should be "ti,am335-sdhci" for am335x controllers 11 Should be "ti,am437-sdhci" for am437x controllers 12- ti,hwmods: Must be "mmc<n>", <n> is controller instance starting 1 13 (Not required for K2G). 14- pinctrl-names: Should be subset of "default", "hs", "sdr12", "sdr25", "sdr50", 15 "ddr50-rev11", "sdr104-rev11", "ddr50", "sdr104", 16 "ddr_1_8v-rev11", "ddr_1_8v" or "ddr_3_3v", "hs200_1_8v-rev11", 17 "hs200_1_8v", 18- pinctrl-<n> : Pinctrl states as described in bindings/pinctrl/pinctrl-bindings.txt 19 20Optional properties: 21- dmas: List of DMA specifiers with the controller specific format as described 22 in the generic DMA client binding. A tx and rx specifier is required. 23- dma-names: List of DMA request names. These strings correspond 1:1 with the 24 DMA specifiers listed in dmas. The string naming is to be "tx" 25 and "rx" for TX and RX DMA requests, respectively. 26 27Example: 28 mmc1: mmc@4809c000 { 29 compatible = "ti,dra7-sdhci"; 30 reg = <0x4809c000 0x400>; 31 ti,hwmods = "mmc1"; 32 bus-width = <4>; 33 vmmc-supply = <&vmmc>; /* phandle to regulator node */ 34 dmas = <&sdma 61 &sdma 62>; 35 dma-names = "tx", "rx"; 36 }; 37
