The RFC version of this series was posted long time back, around December last year [1]. This series is based on Heikki's patches for simpliefied phy lookup table: [PATCHv2 0/6] phy: simplified phy lookup [2], applied against 'usb-next' branch of Greg's usb tree. Tested on peach-pit boards with SuperSpeed devices and confirmed that now the devices are detected as SupedSpeed, not as HighSpeed. Explanation for the need of this patch-series: "The DWC3-exynos eXtensible host controller present on Exynos5420 SoC is quirky. The PHY serving this controller operates at High-Speed by default, so it detects even Super-speed devices as high-speed ones. Certain PHY parameters like Tx LOS levels and Boost levels need to be calibrated further post initialization of xHCI controller, to get SuperSpeed operations working."
