2018-05-24usb: mtu3: avoid sleep in atomic context when enter test modeChunfeng Yun1-1/+1
Use readl_poll_timeout_atomic() instead of readl_poll_timeout() in atomic context Signed-off-by: Chunfeng Yun <chunfeng.yun@mediatek.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2018-05-15usb: mtu3: fix operation failure when test TEST_J/KChunfeng Yun1-0/+10
There is an error dialog popped up in PC when test TEST_J/K by EHSETT tool, due to not waiting for the completion of control transfer. Here fix it by entering test mode after Status Stage finish.

2018-05-15usb: mtu3: avoid TX data length truncated in SS/SSP modeChunfeng Yun1-1/+1
The variable of 'count' is declared as u8, this will cause an issue due to value truncated when works in SS or SSP mode and data length is greater than 255, so change it as u32. Signed-off-by: Chunfeng Yun <chunfeng.yun@mediatek.com> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>
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.

Support SuperSpeedPlus for usb3.1 device IP Signed-off-by: Chunfeng Yun <chunfeng.yun@mediatek.com> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>
2017-07-30usb: mtu3: handle delayed status of the control transferChunfeng Yun1-3/+20
Add the delayed status handling. This is used by mass storage etc to gain some extra time to setup its internal status before it can proceed further requests, and once the gadget is ready, it will enqueue an empty packet which is used for synchronization. The issue may happen on some FGPA platform with very low cpu frequency. Signed-off-by: Chunfeng Yun <chunfeng.yun@mediatek.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2016-10-27usb: Add MediaTek USB3 DRD driverChunfeng Yun1-0/+791
This patch adds support for the MediaTek USB3 controller integrated into MT8173. It currently supports High-Speed Peripheral Only mode. Super-Speed Peripheral, Dual-Role Device and Host Only (xHCI) modes will be added in the next patchs.
