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