| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When re-applying the configuration after a successful usb device reset, xhci_discover_or_reset_device has already dropped the endpoints, and free-ed the rings. The endpoints already being dropped is expected, and should not lead to warnings.

| * | USB: ehci-platform: Support ehci reset after resume quirkWu Liang feng2015-01-09

Specifically, when usb resume from suspend, the EHCI controller maintaining the USB state (FLAG_CF is 1, Current Connect Status is 1), but a USB device (like a USB camera on rk3288) may have been disconnected actually. Let's add a quirk to force ehci to go into the usb_root_hub_lost_power() path and reset after resume. This should generally reset the whole controller and all ports and initialize everything cleanly again, and bring the devices back up. As part of this, rename the "hibernation" paramter of ehci_resume() to force_reset since hibernation is simply another case where we can't trust the autodetected status and need to force a reset of devices.

The code path that was previously specific to NVIDIA controllers had then become taken for all chips.

Don't readl() and writel() base+OHCI_FMINTERVAL on PCI ID 10b9:5237. The patch is suitable for the -next tree as well as all maintained kernels up to 3.2 inclusive.

* | USB: EHCI: adjust error return codeAlan Stern2015-01-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The USB stack uses error code -ENOSPC to indicate that the periodic schedule is too full, with insufficient bandwidth to accommodate a new allocation. It uses -EFBIG to indicate that an isochronous transfer could not be linked into the schedule because it would exceed the number of isochronous packets the host controller driver can handle (generally because the new transfer would extend too far into the future). ehci-hcd uses the wrong error code at one point.

However, the new code it added used ehci->last_iso_frame before the value was properly initialized.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Endpoints halted on errors, and endpoints stopped manually both used the same ep->stopped_td to store the halted or stopped td. this causes confusion and possible races. There is no longer a need to use the ep->stopped_td variable to store the halted TD. A halted endpoint is handled immediately and we can pass it to the handling function directly.

Most of the commits contained here are sparse or coccinelle fixes ranging from missing 'static' to returning 0 in case of errors. More importantly, we have the removal the now unnecessary 'driver' argument to ->udc_stop(). DWC2 learned about Dual-Role builds. Users of this IP can now have a single driver built for host and device roles. DWC3 got support for two new HW platforms: Exynos7 and AMD. The Broadcom USB 3.0 Device Controller IP is now supported and so is PLX USB338x, which means DWC3 has lost is badge as the only USB 3.0 peripheral IP supported on Linux. Thanks for Tony Lindgren's work, we can now have a distro-like kernel where all MUSB glue layers can be built into the same kernel (statically or dynamically linked) and it'll work in PIO (DMA will come probably on v3.20). Other than these, the usual set of cleanups and non-critical fixes. Signed-off-by: Felipe Balbi <balbi@ti.com>

This patch moves the OTG state into the OTG structure, and makes all the needed modifications in the drivers using the OTG state.
