D-Link DWN-652 in Modem mode exposes 3 interfaces - First one is the USB storage one - Second one is for both control and connection - Third one is unknown This patch avoids usb-storage trying to switch again when already in modem mode, and exposes only 2 ttyUSB instead of 3 by not attaching to the storage interface Signed-off-by:

Modern systems do not use usbfs; the entries within it are files, not device nodes, and do not support ACLs which are the default way to provide access to USB devices to untrusted users. It is replaced by device-nodes maintained by udev in /dev/bus/usb, libusb uses this device nodes. Mark the option as deprecated, and hide entirely for non-embedded builds (which may not be using udev but require raw USB device access). Signed-off-by:

This patch (as1230) consolidates code in usb_unbind_interface() and usb_driver_release_interface(). In fact, it makes release_interface call unbind_interface, thereby removing the need for duplicated code. It works like this: If the interface has already been registered with the driver core when a driver releases it, then the usual driver-core mechanism will call unbind_interface. If it hasn't been unregistered then we will make the call ourselves. As a nice bonus, drivers now don't have to worry about whether their disconnect method will get called when they release an interface -- it always will. Previously it would be called only if the interface was registered. Signed-off-by:

Added a function to set the packet size to be used based on the value from the device endpoint descriptor. The FT2232H and FT4232H hi-speed devices will have wMaxPacketSize of 512 bytes when connected to a USB 2.0 hi-speed host, but will use alternative descriptors with wMaxPacketSize of 64 bytes if connected to a USB 1.1 host or hub. All other FTDI devices have wMaxPacketSize of 64 bytes, except some FT232R and FT245R devices which customers have mistakenly programmed to have wMaxPacketSize of 0 - this is an error and will be overridden to use wMaxPacketSize of 64 bytes. The packet size used is important as it determines where the driver removes the status bytes from the incoming data. If it is incorrect, it will lead to data corruption. Signed-off-by:

Added support for FTDI's USB 2.0 hi-speed devices - FT2232H (2 interfaces) and FT4232H (4 interfaces), including a new baud rate calculation for these devices which can now achieve up to 12Mbaud by turning off a divide by 2.5 in the baud rate generator of the chips. In order to achieve baud rates of <1200 baud, the divide by 2.5 must be active. The default product ID of the FT2232H is 0x6010 (same as the FT2232C IC). The default PID of the FT4232H is 0x6011.

Tested on OMAP3 host side with Creative (Live! Cam Optia) USB camera which uses high bandwidth isochronous IN endpoints. FIFO mode 4 is updated to provide the needed 4K endpoint buffer without breaking the g_nokia composite gadget configuration. (This is the only gadget driver known to use enough endpoints to notice the change.) Signed-off-by:

Currently, with Inventra DMA, we use Mode 0 if transfer size is less than or equal to the endpoint's maxpacket size. This requires that we explicitly set TXPKTRDY for that transfer. However the musb_g_tx code will not set TXPKTRDY twice if the last transfer is exactly equal to maxpacket, even if request->zero is set. Using Mode 1 will solve this; a better fix might be in musb_g_tx(). Without this change, musb will not correctly send out a ZLP if the last transfer is the maxpacket size and request->zero is set.

Adjust HNP state machines in MUSB driver so that they handle the case where the cable is disconnected. The A-side machine was very wrong (unrecoverable); the B-Side was much less so. - A_PERIPHERAL ... as usual, the non-observability of the ID pin through Mentor's registers makes trouble. We can't go directly to A_WAIT_VFALL to end the session and start the disconnect processing. We can however sense link suspending, go to A_WAIT_BCON, and from there use OTG timeouts to finally trigger that A_WAIT_VFALL transition. (Hoping that nobody reconnects quickly to that port and notices the wrong state.) - B_HOST ... actually clear the Host Request (HR) bit as the messages say, disconnect the peripheral from the root hub, and don't detour through a suspend state. (In some cases this would eventually have cleaned up.) Also adjust the A_SUSPEND transition to respect the A_AIDL_BDIS timeout, so if HNP doesn't trigger quickly enough the A_WAIT_VFALL transition happens as it should. Signed-off-by:

Minor HNP bugfixes, so the initial role switch works: - A-Device: * disconnect-during-suspend enters A_PERIPHERAL state * kill OTG timer after reset as A_PERIPHERAL ... * ... and also pass that reset to the gadget * once HNP succeeds, clear the "ignore_disconnect" flag * from A_PERIPHERAL, disconnect transitions to A_WAIT_BCON - B-Device: * kill OTG timer on entry to B_HOST state (HNP succeeded) * once HNP succeeds, clear "ignore_disconnect" flag * kick the root hub only _after_ the state is adjusted Other state transitions are left alone. Notably, exit paths from the "roles have switched" state ... A_PERIPHERAL handling of that stays seriously broken. Signed-off-by: -

Minor cleanup of OTG timer handling: * unify decls for OTG time constants, in the core header * set up and use that timer in a more normal way * move to the driver struct, so it's usable outside core And tighten use and setup of T(a_wait_bcon) so that if it's used, it's always valid. (If that timer expires, the A-device will stop powering VBUS. For non-OTG systems, that will be a surprise.) No behavioral changes, other than more consistency when applying that core HNP timeout.

Let the otg_transceiver in MUSB be managed by an external driver; don't assume it's integrated. OMAP3 chips need it to be external, and there may be ways to interact with the transceiver which add functionality to the system. Platform init code is responsible for setting up the transeciver, probably using the NOP transceiver for integrated transceivers. External ones will use whatever the board init code provided, such as twl4030 or something more hands-off. Signed-off-by:

Fix a reporting glitch in the twl4030 USB transceiver code. It wasn't properly distinguishing the two types of active USB link: ID grounded, vs not. In the current code that distinction doesn't much matter; in the future this bugfix should help support better USB controller communications. Provide a comment sorting out some of the cryptic bits of the manual: different sections use different names for key signals, and the register definitions don't help much without the explanations and diagrams.

A pointer to ehci_orion_drv_probe is passed to the core via platform_driver_register and so the function must not disappear when the .init sections are discarded. Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late. An alternative to this patch is using platform_driver_probe instead of platform_driver_register plus removing the pointer to the probe function from the struct platform_driver. Signed-off-by:

The argument for the 'is_in' parameter of musb_cleanup_urb() is always extracted from an URB that's passed to the function. So that parameter is superfluous; remove it. Signed-off-by:
-
Sergei Shtylyov authored
The existance of the scheduling list shouldn't matter in determining whether there's currectly an URB executing on a hardware endpoint. What should actually matter is the 'in_qh' or 'out_qh' fields of the 'struct musb_hw_ep' -- those are set in musb_start_urb() and cleared in musb_giveback() when the endpoint's URB list drains. Hence we should be able to replace the big *switch* statements in musb_urb_dequeue() and musb_h_disable() with mere musb_ep_get_qh() calls... While at it, do some more changes: - add 'is_in' variable to musb_urb_dequeue(); - remove the unnecessary 'epnum' variable from musb_h_disable(); - fix the comment style in the vicinity. This is a minor shrink of source and object code. Signed-off-by:

Factor out the often used code to get/set the active 'qh' pointer for the hardware endpoint. Change the way the case of a shared FIFO is handled by setting *both* 'in_qh' and 'out_qh' fields of 'struct musb_hw_ep'. That seems more consistent and makes getting to the current 'qh' easy when the code knows the direction beforehand. While at it, turn some assignments into intializers and fix declaration style in the vicinity. Signed-off-by:

Refactor musb_save_toggle() as follows: - replace 'struct musb_hw_ep *ep' parameter by 'struct musb_qh *qh' to avoid re-calculating this value - move usb_settogle() call out of the *if* operator. This is a net minor shrink of source and object code. Signed-off-by:

Suppress "parasitic" endpoint interrupts in the DMA mode when using CPPI DMA driver; they're caused by the MUSB gadget driver using the DMA request mode 0 instead of the mode 1. Signed-off-by:
-
Sergei Shtylyov authored
The gadget EP0 code routinely ignores an interrupt at end of the data phase because of musb_g_ep0_giveback() resetting the state machine to "idle, waiting for SETUP" phase prematurely. The driver also prematurely leaves the status phase on receiving the SetupEnd interrupt. As there were still unhandled endpoint 0 interrupts happening from time to time after fixing these issues, there turned to be yet another culprit: two distinct gadget states collapsed into one. The (missing) state that comes after STATUS IN/OUT states was typically indiscernible from them since the corresponding interrupts tend to happen within too little period of time (due to only a zero-length status packet in between) and so they got coalesced; yet this state is not the same as the next one which is associated with the reception of a SETUP packet. Adding this extra state seems to have fixed the rest of the unhandled interrupts that generic_interrupt() and davinci_interrupt() hid by faking their result and only emitting a debug message -- so, stop doing that.
