| * 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>; |
| } |
