usb: dwc3: host: pass quirk-broken-port-ped property for known broken revisions

2017-04-12T10:42:10+00:00

[ Upstream commit e42a5dbb8a3d14f5a35bffa3bf7dcb87883f767a ] dwc3 revisions <=3.00a have a limitation where Port Disable command doesn't work. Set the quirk-broken-port-ped property for such controllers so XHCI core can do the necessary workaround. [rogerq@ti.com] Updated code from platform data to device property.

usb: dwc3: gadget: delay unmap of bounced requests

2017-04-12T10:42:09+00:00

commit de288e36fe33f7e06fa272bc8e2f85aa386d99aa upstream. In the case of bounced ep0 requests, we must delay DMA operation until after ->complete() otherwise we might overwrite contents of req->buf. This caused problems with RNDIS gadget. Signed-off-by: Janusz Dziedzic Signed-off-by: Felipe Balbi Signed-off-by: Greg Kroah-Hartman

usb: dwc3-omap: Fix missing break in dwc3_omap_set_mailbox()

commit 0913750f9fb6f26bcd00c8f9dd9a8d1b8d031246 upstream. We need to break from all cases if we want to treat each one of them separately. Reported-by: Gustavo A. R.

usb: dwc3: gadget: make Set Endpoint Configuration macros safe

2017-03-18T11:18:40+00:00

commit 7369090a9fb57c3fc705ce355d2e4523a5a24716 upstream. Some gadget drivers are bad, bad boys. We notice that ADB was passing bad Burst Size which caused top bits of param0 to be overwritten which confused DWC3 when running this command. In order to avoid future issues, we're going to make sure values passed by macros are always safe for the controller. Note that ADB still needs a fix to *not* pass bad values.

usb: dwc3: gadget: skip Set/Clear Halt when invalid

2017-03-12T05:44:16+00:00

commit ffb80fc672c3a7b6afd0cefcb1524fb99917b2f3 upstream. At least macOS seems to be sending ClearFeature(ENDPOINT_HALT) to endpoints which aren't Halted. This makes DWC3's CLEARSTALL command time out which causes several issues for the driver. Instead, let's just return 0 and bail out early.

usb: dwc3: exynos fix axius clock error path to do cleanup

Axius clock error path returns without disabling clock and suspend clock. Fix it to disable them before returning error. Reviewed-by: Javier Martinez Canillas Signed-off-by: Shuah Khan Signed-off-by: Felipe Balbi

usb: dwc3: gadget: Fix full speed mode

2017-01-03T12:33:48+00:00

DCFG.DEVSPD == 0x3 is not valid and we need to set DCFG.DEVSPD to 0x1 for full speed mode. Same goes for DSTS.CONNECTSPD. Old databooks had 0x3 for full speed in 48MHz mode for USB1.1 transceivers which was never supported. Newer databooks don't mention 0x3 at all.

usb: dwc3: pci: Add "linux,sysdev_is_parent" property

2017-01-02T08:55:28+00:00

Calling platform_device_add_properties() replaces existing properties so the "linux,sysdev_is_parent" property doesn't get set. Add this property to each platform. Fixes: d64ff406e51e ("usb: dwc3: use bus->sysdev for DMA configuration") Signed-off-by: John Youn Signed-off-by: Felipe Balbi

usb: dwc3: omap: fix race of pm runtime with irq handler in probe

2017-01-02T08:55:28+00:00

Now races can happen between interrupt handler execution and PM runtime in error handling code path in probe and in dwc3_omap_remove() which will lead to system crash: in probe: ... err1: pm_runtime_put_sync(dev); ^^ PM runtime can race with IRQ handler when deferred probing happening due to extcon pm_runtime_disable(dev); return ret; in dwc3_omap_remove: ... dwc3_omap_disable_irqs(omap); ^^ IRQs are disabled in HW, but handler may still run of_platform_depopulate(omap->dev); pm_runtime_put_sync(&pdev->dev); ^^ PM runtime can race with IRQ handler pm_runtime_disable(&pdev->dev); return 0; So, OMAP DWC3 IRQ need to be disabled before calling pm_runtime_put() in probe and in dwc3_omap_remove().
