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.

Srinath Mannam (4):
  phy: Add phy ports in attrs
  dt-bindings: phy: Modify Stingray USB PHY #phy-cells
  phy: sr-usb: Set phy ports
  dt-bindings: usb-xhci: Add platform specific compatible for Stingray
    xHCI
  drivers: xhci: Add quirk to reset xHCI port PHY
