1* TI OMAP SDHCI Controller2 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 controllers9 Should be "ti,omap3-sdhci" for omap3 controllers10 Should be "ti,omap4-sdhci" for omap4 and ti81 controllers11 Should be "ti,omap5-sdhci" for omap5 controllers12 Should be "ti,dra7-sdhci" for DRA7 and DRA72 controllers13 Should be "ti,k2g-sdhci" for K2G14 Should be "ti,am335-sdhci" for am335x controllers15 Should be "ti,am437-sdhci" for am437x controllers16- ti,hwmods: Must be "mmc<n>", <n> is controller instance starting 117 (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.txt23 24Optional properties:25- dmas: List of DMA specifiers with the controller specific format as described26 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 the28 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 property33 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 };44
