1*4882a593Smuzhiyun* TI OMAP SDHCI Controller 2*4882a593Smuzhiyun 3*4882a593SmuzhiyunRefer to mmc.txt for standard MMC bindings. 4*4882a593Smuzhiyun 5*4882a593SmuzhiyunFor 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*4882a593Smuzhiyun 7*4882a593SmuzhiyunRequired properties: 8*4882a593Smuzhiyun- compatible: Should be "ti,dra7-sdhci" for DRA7 and DRA72 controllers 9*4882a593Smuzhiyun Should be "ti,k2g-sdhci" for K2G 10*4882a593Smuzhiyun Should be "ti,am335-sdhci" for am335x controllers 11*4882a593Smuzhiyun Should be "ti,am437-sdhci" for am437x controllers 12*4882a593Smuzhiyun- ti,hwmods: Must be "mmc<n>", <n> is controller instance starting 1 13*4882a593Smuzhiyun (Not required for K2G). 14*4882a593Smuzhiyun- pinctrl-names: Should be subset of "default", "hs", "sdr12", "sdr25", "sdr50", 15*4882a593Smuzhiyun "ddr50-rev11", "sdr104-rev11", "ddr50", "sdr104", 16*4882a593Smuzhiyun "ddr_1_8v-rev11", "ddr_1_8v" or "ddr_3_3v", "hs200_1_8v-rev11", 17*4882a593Smuzhiyun "hs200_1_8v", 18*4882a593Smuzhiyun- pinctrl-<n> : Pinctrl states as described in bindings/pinctrl/pinctrl-bindings.txt 19*4882a593Smuzhiyun 20*4882a593SmuzhiyunOptional properties: 21*4882a593Smuzhiyun- dmas: List of DMA specifiers with the controller specific format as described 22*4882a593Smuzhiyun in the generic DMA client binding. A tx and rx specifier is required. 23*4882a593Smuzhiyun- dma-names: List of DMA request names. These strings correspond 1:1 with the 24*4882a593Smuzhiyun DMA specifiers listed in dmas. The string naming is to be "tx" 25*4882a593Smuzhiyun and "rx" for TX and RX DMA requests, respectively. 26*4882a593Smuzhiyun 27*4882a593SmuzhiyunExample: 28*4882a593Smuzhiyun mmc1: mmc@4809c000 { 29*4882a593Smuzhiyun compatible = "ti,dra7-sdhci"; 30*4882a593Smuzhiyun reg = <0x4809c000 0x400>; 31*4882a593Smuzhiyun ti,hwmods = "mmc1"; 32*4882a593Smuzhiyun bus-width = <4>; 33*4882a593Smuzhiyun vmmc-supply = <&vmmc>; /* phandle to regulator node */ 34*4882a593Smuzhiyun dmas = <&sdma 61 &sdma 62>; 35*4882a593Smuzhiyun dma-names = "tx", "rx"; 36*4882a593Smuzhiyun }; 37
