| * smsc95xx: Fetch whole burst with 1 URB, avoid framing errorsStefan Brüns2015-10-28-3/+4
| | | | | | | | | | | | | | | | | | | | | | smsc95xx_recv() does not reassemble bursts spread over multiple URBs. If there is a lot of broadcast traffic, the fifo will fill up to the burst cap limit. Lowering the burst cap to the URB size ensures no packet spans multiple urbs. Caveat, lower limit for working burst cap is 5/33 HS/FS packets.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This arch does not seem to be supported / used at all in the current U-Boot mainline source tree any more. So lets remove the core u8500 code and code that was only referenced by this platform.

* usb: ci_udc: fix emissions of ZLPsStephen Warren2015-09-12-10/+8
| | | | | | | | | | | | | | | | | | | Commit 6a132416359e "ci_udc: Update the ci_udc driver to support bulk transfers" caused the value of "len" to change without updating subsquent users of that variable in ci_ep_submit_next_request(). This caused the code that detects when to emit ZLPs (Zero Length Packets) never to trigger, which in turn caused host timeouts when a ZLP was required, which in turn broke tests/dfu/, even despite the assertion in that commit's description that "These changes are tested for both the DFU and lthor." Fix this by modifying the added dtd iteration code not to modify "len", but rather to keep state in a separate variable. Rename the variables while we're at it so they describe their purpose better.

* usb: gadget: don't leak configs when unbindingStephen Warren2015-09-11-2/+1
| | | | | | | | | | | | | | | | By the time g_dnl_unbind() is run, cdev->config has been set to NULL, so the free() there does nothing, and the config struct is leaked. Equally, struct usb_gadget contains a linked list of config structs, so the code should iterate over them all and free each one, rather than freeing one particular config struct. composite_unbind() already iterates over the list of config structs, and unlinks each from the linked list. Fix this loop to free() each struct as it's unlinked and otherwise forgotten.

Looking at the surrounding code, I found the same problem in all other composite gadget drivers in both the bind and unbind functions, as well as the udc platform driver 'remove' functions. Those will break if anyone uses the 'unbind' sysfs attribute to detach a device from a built-in driver. This patch removes the incorrect annotations from all the gadget drivers.

* usb: ehci: remember init modeStephen Warren2015-09-07-1/+7
| | | | | | | | | | | | | | When an EHCI device is registered in device mode, the HW isn't actually initialized at all, and hence isn't left in a running state. Consequently, when the device is deregistered, ehci_shutdown() will fail, since the HW bits it expects to see set in response to its shutdown requests will not be sent, and the message "EHCI failed to shut down host controller." will be printed. Fix ehci-hcd.c to remember whether the device was registered in host or device mode, and only call ehci_shutdown() for host mode registrations. Signed-off-by: Stephen Warren <swarren@nvidia.com>

| | | | | | | | | | | | | | | | | This patch enables the USB EHCI support for the Marvell Armada XP (AXP) SoCs.

Without this, accessing the controller registers in U-Boot or Linux will hang the CPU. Additionally, the AXP uses a different USB EHCI base address.

| | | | | | | | | | | | | | | | | | | | | USB devices are not really designed to get the power bounced off and on at them. Esp. USB powered harddisks do not like this. Currently we power off the USB ports both on a "usb reset" and when booting the kernel, causing the usb-power to bounce off and then back on again. This patch removes the powering off calls, fixing the undesirable power bouncing. Note this requires some special handling for the OTG port: 1) We must skip the external vbus check if we've already enabled our own vbus to avoid false positives 2) If on an usb reset we no longer detect that the id-pin is grounded, turn off vbus as that means an external vbus may be present now Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
