Subject: [PATCH v2 0/6] add USB Type-B GPIO based role switch driver
Date: Fri, 15 Mar 2019 15:38:27 +0800 [thread overview]
Message-ID: <1552635513-2378-1-git-send-email-chunfeng.yun@mediatek.com> (raw)
Because the USB Connector is introduced and the requirement of
usb-connector.txt binding, the old way using extcon to support
USB Dual-Role switch is now deprecated, meanwhile there is no
available common driver when use Type-B connector.
This patch series introduce a Type-B connector driver and try
to replace the function provided by extcon-usb-gpio driver.
The main purpose of the patches is also to solve the Type-B
connector problem encountered in [1].
[1]: https://patchwork.kernel.org/patch/10819377/
v2 changes:
1. make binding clear, and add a extra compatible suggested by Hans
Chunfeng Yun (6):
dt-bindings: connector: add optional properties for Type-B
dt-bindings: usb: add binding for Type-B dual role switch by GPIO
dt-bindings: usb: mtu3: add properties about USB Role Switch
usb: roles: add API to get usb_role_switch by node
usb: roles: add driver of USB Type-B role switch by GPIO
usb: mtu3: register a USB Role Switch for dual role mode
