On qcom SD host controllers voltage switching be done after the HW is ready for it. The HW informs its readiness through power irq. The voltage switching should happen only then. Use the internal voltage switching and then control the voltage switching using power irq. IO-bus supply of eMMC would be kept always-on. So set the load for this supply to configure it in LPM when eMMC is suspend state and in HPM when eMMC is active.
