-* TI OMAP SDHCI Controller
-
-Refer to mmc.txt for standard MMC bindings.
-
-For 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.
-
-Required properties:
-- compatible: Should be "ti,omap2430-sdhci" for omap2430 controllers
- Should be "ti,omap3-sdhci" for omap3 controllers
- Should be "ti,omap4-sdhci" for omap4 and ti81 controllers
- Should be "ti,omap5-sdhci" for omap5 controllers
- Should be "ti,dra7-sdhci" for DRA7 and DRA72 controllers
- Should be "ti,k2g-sdhci" for K2G
- Should be "ti,am335-sdhci" for am335x controllers
- Should be "ti,am437-sdhci" for am437x controllers
-- ti,hwmods: Must be "mmc<n>", <n> is controller instance starting 1
- (Not required for K2G).
-- pinctrl-names: Should be subset of "default", "hs", "sdr12", "sdr25", "sdr50",
- "ddr50-rev11", "sdr104-rev11", "ddr50", "sdr104",
- "ddr_1_8v-rev11", "ddr_1_8v" or "ddr_3_3v", "hs200_1_8v-rev11",
- "hs200_1_8v",
-- pinctrl-<n> : Pinctrl states as described in bindings/pinctrl/pinctrl-bindings.txt
-
-Optional properties:
-- dmas: List of DMA specifiers with the controller specific format as described
- in the generic DMA client binding. A tx and rx specifier is required.
-- dma-names: List of DMA request names. These strings correspond 1:1 with the
- DMA specifiers listed in dmas. The string naming is to be "tx"
- and "rx" for TX and RX DMA requests, respectively.
-
-Deprecated properties:
-- ti,non-removable: Compatible with the generic non-removable property
-
-Example:
- mmc1: mmc@4809c000 {
- compatible = "ti,dra7-sdhci";
- reg = <0x4809c000 0x400>;
- ti,hwmods = "mmc1";
- bus-width = <4>;
- vmmc-supply = <&vmmc>; /* phandle to regulator node */
- dmas = <&sdma 61 &sdma 62>;
- dma-names = "tx", "rx";
- };
