Subject: [PATCH v7 00/10] add USB Type-B GPIO connector driver
Date: Tue, 11 Jun 2019 16:44:30 +0800 [thread overview]
Message-ID: <1560242680-23844-1-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.
v7 changes:
1. [5/10]: add signed-off-by Chunfeng
2. [6/10]: add signed-off-by Chunfeng
3. [6/10]: depends on linux-next of Rafael's tree [1]
4. [7/10]: add signed-off-by Chunfeng and tested-by Biju
5. [9/10]: add tested-by Nagarjuna, and remove DEV_PMS_OPS suggested by Andy
[1] https://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git/log/?h=linux-next
v6 changes:
1. merge [1] and [2] into this series
2. don't use graph anymore to find usb-role-switch
3. abandon [3] and introduce three patches (6, 7, 8 in this series)
to rebuild APIs getting usb-role-switch
[1]: [v3] dt-binding: usb: add usb-role-switch property
https://patchwork.kernel.org/patch/10934835/
[2]: [v6,08/13] usb: roles: Introduce stubs for the exiting functions in role.h
https://patchwork.kernel.org/patch/10909971/
[3]: [PATCH v5 4/6] usb: roles: add API to get usb_role_switch by node
v5 changes:
1. remove linux/of.h and put usb_role_switch when error happens,
suggested by Biju
2. treat Type-B connector as USB controller's child, but not as
a virtual device, suggested by Rob
3. provide and use generic property "usb-role-switch", see [1],
suggested by Rob
Note: this series still depends on [2]
[1]: [v3] dt-binding: usb: add usb-role-switch property
https://patchwork.kernel.org/patch/10934835/
[2]: [v6,08/13] usb: roles: Introduce stubs for the exiting functions in role.h
https://patchwork.kernel.org/patch/10909971/
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 (7):
dt-binding: usb: add usb-role-switch property
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: get usb-role-switch from parent
usb: roles: add USB Type-B GPIO connector driver
usb: mtu3: register a USB Role Switch for dual role mode
Heikki Krogerus (2):
device connection: Add fwnode_connection_find_match()
usb: roles: Add fwnode_usb_role_switch_get() function
Yu Chen (1):
usb: roles: Introduce stubs for the exiting functions in role.h.
