Subject: [PATCH v1 0/4] Fine tune USB 3.0 PHY on exynos5420
Date: Fri, 6 Jun 2014 17:42:11 +0530 [thread overview]
Message-ID: <1402056736-12674-1-git-send-email-gautam.vivek@samsung.com> (raw)
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."
