Subject: [PATCH v2 0/4] Reset xHCI port PHY on disconnect
Date: Wed, 31 Jul 2019 15:49:50 +0530 [thread overview]
Message-ID: <1564568395-9980-1-git-send-email-srinath.mannam@broadcom.com> (raw)
This patch set adds a quirk in xHCI driver to reset PHY of xHCI port on
its disconnect event.
This patch set is based on Linux-5.2-rc4.
Changes from v1:
- Addressed Mathias's comments
- Modified mapping of HC ports and their corresponding PHYs
- Addressed Rob's comments
- Removed usb-phy-port-reset DT property.
- Added quirk in platform data using HCI compatible string.
- Add phy ports in phy attr structure to have enabled ports bitmask.
- Modified #phy-cells of sr-phy to pass phy ports bitmask.

phy: sr-usb: Set phy ports
dt-bindings: usb-xhci: Add platform specific compatible for Stingray
