|  | * The simple MMC power sequence provider | 
|  |  | 
|  | The purpose of the simple MMC power sequence provider is to supports a set of | 
|  | common properties between various SOC designs. It thus enables us to use the | 
|  | same provider for several SOC designs. | 
|  |  | 
|  | Required properties: | 
|  | - compatible : contains "mmc-pwrseq-simple". | 
|  |  | 
|  | Optional properties: | 
|  | - reset-gpios : contains a list of GPIO specifiers. The reset GPIOs are asserted | 
|  | at initialization and prior we start the power up procedure of the card. | 
|  | They will be de-asserted right after the power has been provided to the | 
|  | card. | 
|  | - clocks : Must contain an entry for the entry in clock-names. | 
|  | See ../clocks/clock-bindings.txt for details. | 
|  | - clock-names : Must include the following entry: | 
|  | "ext_clock" (External clock provided to the card). | 
|  |  | 
|  | Example: | 
|  |  | 
|  | sdhci0_pwrseq { | 
|  | compatible = "mmc-pwrseq-simple"; | 
|  | reset-gpios = <&gpio1 12 0>; | 
|  | } |
