| * 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"; |
| }; |
