7 title: Simple MMC power sequence provider
10   - Ulf Hansson <ulf.hansson@linaro.org>
13   The purpose of the simple MMC power sequence provider is to supports a set
14   of common properties between various SOC designs. It thus enables us to use
19     const: mmc-pwrseq-simple
21   reset-gpios:
27       at initialization and prior we start the power up procedure of the card.
28       They will be de-asserted right after the power has been provided to the
33     description: Handle for the entry in clock-names.
35   clock-names:
37       - const: ext_clock
40   post-power-on-delay-ms:
42       Delay in ms after powering the card and de-asserting the
43       reset-gpios (if any).
45   power-off-delay-us:
47       Delay in us after asserting the reset-gpios (if any)
48       during power off of the card.
