[Adrian] We can definitely have a single driver to support imx7 and imx6, but we mainly decide to have a driver for each SoC to try to make easier to maintain, there are so many variants of imx6 (Quad/Dual/Solo/SoloX/QuadPlus/UL) and imx7 (Dual/Solo); while there are several similarities in USB IP for iMX6 and iMX7, USB PHY Control and clock settings differ slightly making code harder to Understand and maintain in a single driver for imx7 and imx6.
