The SMSC 3502 HUB has only one USB UICC port. "VBAT only" single supply configuration is used. A gpio is used to control the external oscillator which supplies the ref clock to the HUB. USB UICC card is connected to this HUB on MSM8926. Provide a sysfs interface for userspace to enable/disable the HUB. This is required to save the power when a non-supported card is inserted. The HUB is disabled during boot. If the card is inserted and supports UICC, HUB is enabled by the userspace.
