Zynq soc contains a dual role usb controller and this IP is from synopsys. We observed that there is driver available for this controller from freescale and decided to reuse this driver for zynq use. Here is the link for zynq soc TRM. Please refer chapter 15 for usb controller related information. http://www.xilinx.com/support/documentation/user_guides/ug585-Zynq-7000-TRM.pdf The following series of patches add initial support for zynq soc in fsl gadget controller driver and fsl host controller driver. Based on these patches, I have the following concerns and sugesstions Since the freescale usb driver is for synopsys IP, Please consider rebranding this driver name and config options to reflect that it is a sysnopsys IP. So that other vendors who using this IP can reuse thie driver. Also the ehci-fsl.c is for powerpc based soc's, and zynq is ARM based, i have protected the code which is specifc to freescale with CONFIG_FSL_SOC. Please suggest if there is a better way of doing this?
