The reset GPIOs are asserted at initialization and prior we start the power up procedure of the card. 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).
