Subject: [PATCH v4 0/2] usb: host: ehci-platform: add support for optional external vbus supply
Date: Thu, 1 Mar 2018 10:51:37 +0100 [thread overview]
Message-ID: <1519897899-8577-1-git-send-email-amelie.delaunay@st.com> (raw)
This patchset adds support for optional external vbus supply per port in
ehci-platform.
On some boards, especially when vbus supply requires large current,
and the charge pump on the PHY isn't enough, an external vbus power switch
per port may be used.
---
Changes in v4:
* Address Roger Quadros comments: split dt-bindings and driver changes.
* Address Robin Murphy comments: simplify vbus_spplies initialization.
Changes in v3:
* Address Felipe Balbi comments: reduce indentation in
ehci_platform_port_power.
* Address Roger Quadros and Alan Stern comments: platforms can have one
external vbus supply per port, so add support to get as many optional
regulator as implemented ports on the host controller.
Changes in v2:
* Address Roger Quadros comments: move regulator_enable/disable from
ehci_platform_power_on/off to ehci_platform_port_power.
