Subject: [v4 PATCH 0/6] add USB Type-B GPIO connector driver
Date: Fri, 26 Apr 2019 14:47:11 +0800 [thread overview]
Message-ID: <1556261237-13823-1-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, typically
using an input GPIO to detect USB ID pin.
This patch series introduce a Type-B GPIO connector driver and try
to replace the function provided by extcon-usb-gpio driver.
v4 changes:
1. use switch_fwnode_match() to find fwnode suggested by Heikki
2. assign fwnode member of usb_role_switch struct suggested by Heikki
3. make [4/6] depend on [2]
3. remove linux/gpio.h suggested by Linus
4. put node when error happens
[4/6] usb: roles: add API to get usb_role_switch by node
[2] [v6,08/13] usb: roles: Introduce stubs for the exiting functions in role.h
https://patchwork.kernel.org/patch/10909971/
v3 changes:
1. add GPIO direction, and use fixed-regulator for GPIO controlled
VBUS regulator suggested by Rob;
2. rebuild fwnode_usb_role_switch_get() suggested by Andy and Heikki
3. treat the type-B connector as a virtual device;
4. change file name of driver again
5. select USB_ROLE_SWITCH in mtu3/Kconfig suggested by Heikki
6. rename ssusb_mode_manual_switch() to ssusb_mode_switch()
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 GPIO connector driver
dt-bindings: usb: mtu3: add properties about USB Role Switch
usb: roles: add API to get usb_role_switch by node
usb: roles: add USB Type-B GPIO connector driver
usb: mtu3: register a USB Role Switch for dual role mode
