Required properties:

- compatible: must be "mmc-pwrseq-sd8787".

- powerdown-gpios: contains a power down GPIO specifier with the

		   default active state

- reset-gpios: contains a reset GPIO specifier with the default

		   active state



Example:



	wifi_pwrseq: wifi_pwrseq {

		compatible = "mmc-pwrseq-sd8787";

		powerdown-gpios = <&twl_gpio 0 GPIO_ACTIVE_LOW>;

		reset-gpios = <&twl_gpio 1 GPIO_ACTIVE_LOW>;
