Mainly improve SuperSpeed ISOC bandwidth in last microframe, and LowSpeed/FullSpeed IN INT/ISOC bandwidth in split and idle microframes by introduing a bandwidth budget table; Signed-off-by: Chunfeng Yun <chunfeng.yun@mediatek.com> Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2018-01-09usb: xhci-mtk: supports remote wakeup for mt2712 with two xHCI IPsChunfeng Yun1-1/+5
The old way of usb wakeup only supports platform with single xHCI IP, such as mt8173, but mt2712 has two xHCI IPs, so rebuild its flow and supports the new glue layer of usb wakeup on mt2712 which is different from mt8173. Due to there is a hardware bug with the LINE STATE wakeup mode on mt8173 which causes wakeup failure by low speed devices, and also because IP SLEEP mode can cover all functions of LINE STATE mode, it is unused in fact, and will not support it later, so remove it at the same time.

2017-11-07USB: host: xhci: 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.

2017-10-23usb: xhci-mtk: support option to disable usb3 portsChunfeng Yun1-0/+1
Add support to disable specific usb3 ports, it's useful when usb3 phy is shared with PCIe or SATA, because we should disable the corresponding usb3 port if the phy is used by PCIe or SATA. Sometimes it's helpful to analyse and solve problems.

2015-12-01xhci: mediatek: support MTK xHCI host controllerChunfeng Yun1-0/+162
There some vendor quirks for MTK xhci host controller: 1. It defines some extra SW scheduling parameters for HW to minimize the scheduling effort for synchronous and interrupt endpoints. The parameters are put into reseved DWs of slot context and endpoint context. 2. Its IMODI unit for Interrupter Moderation register is 8 times as much as that defined in xHCI spec. 3. Its TDS in Normal TRB defines a number of packets that remains to be transferred for a TD after processing all Max packets in all previous TRBs.
