2022-07-08usb: mtu3: support function remote wakeupChunfeng Yun1-0/+16
Add function wake notification to support function remote wakeup, currently assume the composite device only enable function wake for the first interface. Forward request to function driver when the recipient is an interface, including: GetStatus() request to the first interface in a function returns the information about 'function remote wakeup' and 'function remote wakeup capalbe'; SetFeature request of FUNCTION_SUSPEND to an interface recipient, the controller driver saves the suspend option; Signed-off-by: Chunfeng Yun <chunfeng.yun@mediatek.com> Link: https://lore.kernel.org/r/20220708071903.25752-5-chunfeng.yun@mediatek.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2020-04-16USB: mtu3: Use the correct style for SPDX License IdentifierNishad Kamdar1-1/+1
This patch corrects the SPDX License Identifier style in header files related to MediaTek USB3 Dual Role controller. For C header files Documentation/process/license-rules.rst mandates C-like comments (opposed to C source files where C++ style should be used). Changes made by using a script provided by Joe Perches here: https://lkml.org/lkml/2019/2/7/46.

2019-03-26usb: mtu3: add debugfs interface filesChunfeng Yun1-0/+11
This adds more debugfs consumers. The debugfs entries read some important registers, fifo status, QMU ring, endpoint status, and IPPC probe interface to get internal status. With these entries, users can check the registers, endpoint and GPD used during run time.

2018-12-05usb: mtu3: clear SOFTCONN when clear USB3_EN if work as HS modeChunfeng Yun1-0/+5
When the controller supports SS mode, but works as HS mode, the SOFTCONN will not be cleared automatically when clear USB3_EN by default, this cause an issue that can't disconnect from host, so clear SOFTCONN when clear USB3_EN when the class driver want to disable the D+ pullup.

2018-12-05usb: mtu3: enable SETUPENDISR interruptChunfeng Yun1-0/+1
If the controller receives a new SETUP during SETUP data stage, and will generate SETUPENDISR interrupt, the driver should abort the current SETUP command and process the new one. Signed-off-by: Chunfeng Yun <chunfeng.yun@mediatek.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2018-09-05usb: mtu3: fix error of xhci port id when enable U3 dual roleChunfeng Yun1-0/+1
If dual role mode is enabled, when switch u3port0 to device mode, it will affect port id calculation of host(xHCI), specially when host supports multi U2 ports or U3 ports, so need enable its dual role mode, and fix it here.

2017-11-07USB: mtu3: Remove redundant license textGreg Kroah-Hartman1-10/+0
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.

2017-11-04USB: add SPDX identifiers to all remaining files in drivers/usb/Greg Kroah-Hartman1-0/+1
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.
