-* 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).
-- post-power-on-delay-ms : Delay in ms after powering the card and
- de-asserting the reset-gpios (if any)
-- power-off-delay-us : Delay in us after asserting the reset-gpios (if any)
- during power off of the card.
-
-Example:
-
- sdhci0_pwrseq {
- compatible = "mmc-pwrseq-simple";
- reset-gpios = <&gpio1 12 GPIO_ACTIVE_LOW>;
- clocks = <&clk_32768_ck>;
- clock-names = "ext_clock";
- }
