These patches add basic support for USB3.0 controllers found on MSM platforms. USB3.0 core is based on Synopsys DesignWare SuperSpeed IP. This work was started by Ivan Ivanov and went through a number of iterations. I picked these patches up and did a little rework to get them working. Changes since v7: * Reworked phy driver to conform to the generic phy framework. * Collapsed HS and SS phy drivers into same source file. * Dropped regulators from the drivers. The only platform where we can utilize this driver has regulators on all the time. Will add regulators back in when they are required. * Added timeouts to the phy register accesses * Put in definitions for the phy specific registers and bitfields * Removed unnecessary workarounds. Changes since v6: * Renamed all MSM references to qcom, including file names * Removed direct TCSR manipulation. This done from new TCSR driver. * Added defines for register bits * XO clk is optional on some platforms. Corrected logic to handle this. * Ignore set_voltage failures. This allows us to support dummy regulators on platforms where there is no voltage control. * Reworked devicetree binding to remove TCSR reg resources Changes since v5: * devicetree bindings descriptions fixes * Fixed NULL pointer dereferences in dev_prink's * Removed extra space in "sleep " clock name Changes since v4: * Substitute references to "wc3" with just "dw" in USB PHY drivers and file names. This is to indicate that the PHY's are DesignWare, but not necessarily related to DWC3 IP core. Changes since v3: * Remove "_clk" suffix from clock names * Clarify required child node for qcom,dwc3 * Fix comments in functions headers * Use dbg instead err in drivers probe functions. Changes since v2: * Several improvements in devicetree bindings description * Disable regulators in glue layer if there is error during ioremap. Changes since first version: * Split devicetree bindings description file to separate patch * Address comments for device bindings description * Fix typo in 'gdsc' requlator name.
