2016-03-03[media] usb: musb: sunxi: support module autoloadingEmilio López
MODULE_DEVICE_TABLE() is missing, so the module isn't auto-loading on sunxi systems using the OTG controller. This commit adds the missing line so it loads automatically when building it as a module and running on a system with an USB OTG port.

2016-03-01Revert "USB: serial: add Moxa UPORT 11x0 driver"Johan Hovold
This reverts commit 0b2b093ad405b56a9e6f4f20a25da77ebfa9549c. Turns out the MOXA vendor driver was basically just a copy of the ti_usb_3410_5052 driver. We don't want two drivers for the same chip even if mxu11x0 had gotten some much needed clean up before merge. So let's remove the mxu11x0 driver, add support for these Moxa devices to the TI driver, and then clean that driver up instead.

This reverts commit e765bfb73ff7. In the most of cases, we only use one transaction per frame and the frame rate may be high, If the platforms want to support multiple transactions but less frame rate cases like [1] and [2], it can set "non-zero-ttctrl-ttha" at dts.

2016-02-29usb: chipidea: add system interface for ttctrl.tthaPeter Chen
In chipidea IP RTL, there is a very limited design for siTD, the detail like below: There is no Max Packet Size at siTD, so it uses one constant for both Max Packet Size for packet and the packet size for the last transaction when considering schedule. If the ttctrl.ttha does not match against Hub Address field in siTD, this constant is 188 bytes, else this constant is 1023 bytes. If the ttctrl.ttha is non-zero value, RTL will use 188 as this constant, so it will lose the data if the packet size is larger than 188 bytes, eg, if we playback a wav which format is 48khz, 16 bits, 2 channels, the packet size will be 192bytes, but the controller will only send 188 bytes for this packet, the noise will be heared using USB audio card. The use case is single transaction, but higher frame rate. If the ttctr.ttha is zero value, we can send 1023 bytes within one transaction, but the controller will not accept the coming tranaction if it considers the schedule time is less than 1023 bytes. So the limitation is we can't schedule as many as transactions within frame. If the total bytes is already 256 bytes for previous transactions within frame, it can't accept another transaction. The use case is multiple transactions, but less frame rate. Signed-off-by: Peter Chen <peter.chen@nxp.com>

2016-02-25usb: chipidea: otg: change workqueue ci_otg as freezablePeter Chen
If we use USB ID pin as wakeup source, and there is a USB block device on this USB OTG (ID) cable, the system will be deadlock after system resume. The root cause for this problem is: the workqueue ci_otg may try to remove hcd before the driver resume has finished, and hcd will disconnect the device on it, then, it will call device_release_driver, and holds the device lock "dev->mutex", but it is never unlocked since it waits workqueue writeback to run to flush the block information, but the workqueue writeback is freezable, it is not thawed before driver resume has finished. When the driver (device: sd 0:0:0:0:) resume goes to dpm_complete, it tries to get its device lock "dev->mutex", but it can't get it forever, then the deadlock occurs. Below call stacks show the situation. So, in order to fix this problem, we need to change workqueue ci_otg as freezable, then the work item in this workqueue will be run after driver's resume, this workqueue will not be blocked forever like above case since the workqueue writeback has been thawed too. Tested at: i.mx6qdl-sabresd and i.mx6sx-sdb.

This time around we will be pre-allocating transfer resources to avoid any future issues; b) two DMA fixes for the old MUSB driver. c) dwc2's data toggle fix for FS Other than these, we have a few other minor fixes elsewhere.
2016-02-23usb: musb: fix DMA for host modeCristian Birsan
Commit ac33cdb16681 ("usb: musb: Remove ifdefs for musb_host_rx in musb_host.c part5") introduces a problem setting DMA host mode. The musb_advance_schedule() is called immediately after receiving an endpoint RX interrupt without waiting for the DMA transfer to complete. As a consequence when the dma complete interrupt arrives the in_qh member of hw_ep is already null an the musb_host_rx() exits on !urb error case. Fix the done condition that advances the musb schedule.

2016-02-23usb: phy: msm: Trigger USB state detection work in DRD modeIvan T. Ivanov
When working in Dual Role Device mode, USB state machine is not kicked, when host or gadget drivers are loaded. Fix this be explicitly triggering state detection on client driver load. Issue is that if the board is booted without micro usb cable and usb device attached, kernel fails to populate the usb host and device. The reason for this is that the state machine worker logic only checks for USB_DR_MODE_PERIPHERAL and USB_DR_MODE_HOST modes to run worker thread. However if the phy is configured in OTG mode it would fail to run the state machine, resulting in failure to detect for very first time. This patch fixes the issue by removing the explicit checks. Issue is noticed on Qualcomm Dragon board DB410C. [srinivas.kandagatla@linaro.org: Added more details to log] Signed-off-by: Ivan T.

There is a case where an address is incorrectly assigned to the DMA channel desired mode when it should instead be assigned the actual mode value. This results in the value of channel->desired_mode not being correct.
