Add the phy provider, supplied by new Exynos-usb2phy using Generic phy framework. Keeping the support for older USB phy intact right now, in order to prevent any functionality break in absence of relevant device tree side change for ehci-exynos. Once we move to new phy in the device nodes for ehci, we can remove the support for older phys. Signed-off-by:

My previous patch introduced a bug which prevented this driver from loading. devm_ioremap_resource() has a call to devm_request_mem_region() which will fail because the address space is shared between this PHY driver and CI device controller driver. Fixes: 10f0577a ('usb: phy: msm: change devm_ioremap() to devm_ioremap_resource()') Reported-by:

The field PLLDIVVALUE of register PHY_CTRL_1 selects the reference clock source for the PHY: 00 = sysclock uses 19.2 MHz 01 = sysclock uses 24 MHz 10 = sysclock uses 26 MHz 11 = sysclock uses 27 MHz The reset value for this field is 10 according to the reference manual, and even though this reset value works for mx53, it does not work for mx51. So instead of relying on the reset value for the PLLDIVVALUE field, explicitly set it to 01 so that a 24MHz clock can be selected for the PHY and allowing both mx51 and mx53 to have USB OTG port functional. Succesfully tested 'g_ether' on a imx51-babbage and on a imx53-qsb boards. Signed-off-by:

Felipe writes: usb: patches for v3.16 merge window Not a lot here during this merge window. Mostly we just have the usual miscellaneous patches (removal of unnecessary prints, proper dependencies being added to Kconfig, build warning fixes, new device ID, etc. Other than those, the only important new features are the new support for OS Strings which should help Linux Gadget Drivers behave better under MS Windows. Also Babble Recovery implementation for MUSB on AM335x. Lastly, we also have ARCH_QCOM PHY support though phy-msm. Signed-of-by:Felipe Balbi <balbi@ti.com> Conflicts: drivers/usb/phy/phy-mv-u3d-usb.c

Use one timer to control command timeout. start/kick the timer every time a command is completed and a new command is waiting, or a new command is added to a empty list. If the timer runs out, then tag the current command as "aborted", and start the xhci command abortion process. Previously each function that submitted a command had its own timer. If that command timed out, a new command structure for the command was created and it was put on a cancel_cmd_list list, then a pci write to abort the command ring was issued. when the ring was aborted, it checked if the current command was the one to be canceled, later when the ring was stopped the driver got ownership of the TRBs in the command ring, compared then to the TRBs in the cancel_cmd_list, and turned them into No-ops. Now, instead, at timeout we tag the status of the command in the command queue to be aborted, and start the ring abortion. Ring abortion stops the command ring and gives control of the commands to us. All the aborted commands are now turned into No-ops. If the ring is already stopped when the command times outs its not possible to start the ring abortion, in this case the command is turnd to No-op right away. All these changes allows us to remove the entire cancel_cmd_list code. The functions waiting for a command to finish no longer have their own timeouts. They will wait either until the command completes normally, or until the whole command abortion is done. Signed-off-by:

Create a list to store command structures, add a structure to it every time a command is submitted, and remove it from the list once we get a command completion event matching the command. Callers that wait for completion will free their command structures themselves. The other command structures are freed in the command completion event handler. Also add a check that prevents queuing commands if host is dying Signed-off-by:

Mathias Nyman authored
To create a global command queue we require that each command put on the command ring is submitted with a command structure. Functions that queue commands and wait for completion need to allocate a command before submitting it, and free it once completed. The following command queuing functions need to be modified. xhci_configure_endpoint() xhci_address_device() xhci_queue_slot_control() xhci_queue_stop_endpoint() xhci_queue_new_dequeue_state() xhci_queue_reset_ep() xhci_configure_endpoint() xhci_configure_endpoint() could already be called with a command structure, and only xhci_check_maxpacket and xhci_check_bandwidth did not do so. These are changed and a command structure is now required. This change also simplifies the configure endpoint command completion handling and the "goto bandwidth_change" handling code can be removed. In some cases the command queuing function is called in interrupt context. These commands needs to be allocated atomically, and they can't wait for completion. These commands will in this patch be freed directly after queuing, but freeing will be moved to the command completion event handler in a later patch once we get the global command queue up.(Just so that we won't leak memory in the middle of the patch set) Signed-off-by:

xHCI host controllers may only support a limited number of device slot IDs, which is usually far less than the theoretical maximum number of devices (255) that the USB specifications advertise. This is frustrating to consumers that expect to be able to plug in a large number of devices. Add a print statement when the Enable Slot command fails to show how many devices the host supports. We can't change hardware manufacturer's design decisions, but hopefully we can save customers a little bit of time trying to debug why their host mysteriously fails when too many devices are plugged in.

In some circumstances when g_audio is being unloaded there happens an endless loop in udc driver. It has happend on a board with s3c-hsotg. If there are requests in endpoint's queue, they are completed in a loop. But completing them might cause appending new requests to the queue. This patch causes agdev_iso_complete() to return immediately if request's status is -ESHUTDOWN. If it does not return immediately, then although the current request is removed from the queue, a new one is appended to the queue, so the above mentioned loop cannot end. Signed-off-by:

Add handling of OS Extended Properties descriptors from configfs interface. One kind of "OS Descriptors" are "Extended Properties" descriptors, which need to be specified per interface or per group of interfaces described by an IAD. This patch adds support for creating subdirectories in interface.<n> directory located in the function's directory. Names of subdirectories created become names of properties. Each property contains two attributes: "type" and "data". The type can be a numeric value 1..7 while data is a blob interpreted depending on the type specified. The types are: 1 - unicode string 2 - unicode string with environment variables 3 - binary 4 - little-endian 32-bit 5 - big-endian 32-bit 6 - unicode string with a symbolic link 7 - multiple unicode strings Signed-off-by:

Add handling of OS Extended Compatibility descriptors from configfs interface. Hosts which expect the "OS Descriptors" ask only for configurations @ index 0, but linux-based USB devices can provide more than one configuration. This patch adds marking one of gadget's configurations the configuration to be reported at index 0, regardless of the actual sequence of usb_add_config invocations used for adding the configurations. The configuration is selected by creating a symbolic link pointing to it from the "os_desc" directory located at the top of a gadget's directory hierarchy. One kind of "OS Descriptors" are "Extended Compatibility Descriptors", which need to be specified per interface. This patch adds interface.<n> directory in function's configfs directory to represent each interface defined by the function. Each interface's directory contains two attributes: "compatible_id" and "sub_compatible_id", which represent 8-byte strings to be reported to the host as the "Compatible ID" and "Sub Compatible ID".
