   12 description:
   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
   15   the same provider for several SOC designs.

   25     description:
   26       contains a list of GPIO specifiers. The reset GPIOs are asserted
   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
   29       card.
