usb: chipidea: Add dynamic pinctrl selection

2018-09-20T09:04:21+00:00

Some hardware implementations require to configure pins differently according to the USB role (host/device), this can be an update of the pins routing or a simple GPIO value change. This patch introduces new optional "host" and "device" pinctrls. If these pinctrls are defined by the device, they are respectively selected on host/device role start. If a default pinctrl exist, it is restored on host/device role stop. Signed-off-by: Loic Poulain Signed-off-by: Peter Chen

USB: chipidea: no need to check return value of debugfs_create functions

2018-05-31T10:54:22+00:00

When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this. Acked-by: Peter Chen Signed-off-by: Greg Kroah-Hartman

USB: move many drivers to use DEVICE_ATTR_RW

2018-01-24T07:49:51+00:00

Instead of "open coding" a DEVICE_ATTR() define, use the DEVICE_ATTR_RW() macro instead, which does everything properly instead. This does require a few static functions to be renamed to work properly, but thanks to a script from Joe Perches, this was easily done.

USB: chipidea: Remove redundant license text

2017-11-07T14:45:01+00:00

Now that the SPDX tag is in all USB files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

USB: add SPDX identifiers to all remaining files in drivers/usb/

2017-11-04T10:48:02+00:00

It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/usb/ and include/linux/usb* files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

usb: chipidea: constify attribute_group structures.

2017-08-10T18:31:28+00:00

attribute_group are not supposed to change at runtime. All functions working with attribute_group provided by work with const attribute_group. So mark the non-const structs as const. Signed-off-by: Arvind Yadav Signed-off-by: Greg Kroah-Hartman

usb: chipidea: core: do not register extcon notifier if extcon device is not existed

This issue is detected when the system has another device driver which registers USB connector extcon device, fix it by adding extcon device check. Signed-off-by: Peter Chen
