/*
 * The signal voltage of sdhci0 and sdhci1 on AST2600-A2 EVB is able to be
 * toggled by GPIO pins.
 * In the reference design, GPIOV0 of AST2600-A2 EVB is connected to the
 * power load switch that provides 3.3v to sdhci0 vdd, GPIOV1 is connected to
 * a 1.8v and a 3.3v power load switch that provides signal voltage to
 * sdhci0 bus.
 * If GPIOV0 is active high, sdhci0 is enabled, otherwise, sdhci0 is disabled.
 * If GPIOV1 is active high, 3.3v power load switch is enabled, sdhci0 signal
 * voltage is 3.3v, otherwise, 1.8v power load switch will be enabled,
 * sdhci0 signal voltage becomes 1.8v.
 * AST2600-A2 EVB also supports toggling signal voltage for sdhci1.
 * The design is the same as sdhci0, it uses GPIOV2 as power-gpio and GPIOV3
 * as power-switch-gpio.
