This patch adds support for EHCI compliant USB Host Controller present in MSM chips. This Controller uses an HSIC PHY which communicates with downstream devices using STROBE/DATA lines. HSIC is a supplement to USB 2.0 specification and is preferred for chip-to-chip interconnect (having maximum circuit length of 10cm) as it removes the analog transceivers.
