Revert "USB: serial: add Moxa UPORT 11x0 driver"

2016-03-01T10:01:33Z

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. Signed-off-by: Johan Hovold Acked-by: Greg Kroah-Hartman

USB: cp210x: Add ID for Parrot NMEA GPS Flight Recorder

2016-02-29T18:01:10Z

The Parrot NMEA GPS Flight Recorder is a USB composite device consisting of hub, flash storage, and cp210x usb to serial chip. It is an accessory to the mass-produced Parrot AR Drone 2. The device emits standard NMEA messages which make the it compatible with NMEA compatible software. It was tested using gpsd version 3.11-3 as an NMEA interpreter and using the official Parrot Flight Recorder. Signed-off-by: Vittorio Alfieri Cc: stable Signed-off-by: Johan Hovold

usb: chipidea: otg: change workqueue ci_otg as freezable

2016-02-25T01:33:29Z

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.

Merge tag 'fixes-for-v4.5-rc6' of http://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-linus

Felipe writes: usb: fixes for v4.5-rc6 The most important fixes here are: a) yet another fix to dwc3's EP transfer resource assignment logic. 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.

usb: musb: fix DMA for host mode

2016-02-23T06:51:38Z

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. Signed-off-by: Cristian Birsan Signed-off-by: Joshua Henderson Tested-by: Ladislav Michl Signed-off-by: Felipe Balbi
