The Buck9 Converter is used as a supply for eMMC Host Controller. BUCK9EN GPIO of S5M8767 chip may be used by application processor to enable or disable the Buck9. This has two benefits: - It is faster than toggling it over I2C bus. - It allows disabling the regulator during suspend to RAM; The AP will enable it during resume; Without the patch the regulator supplying eMMC must be defined as fixed-regulator.
