* musb: add high bandwidth ISO supportAjay Kumar Gupta2009-06-16
| | | | | | | | | | | | 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.)

* musb: use dma mode 1 for TX if transfer size equals maxpacket (v2)Anand Gadiyar2009-06-16
| | | | | | | | | | | | | | | | | | 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.

* musb: support disconnect after HNP roleswitchDavid Brownell2009-06-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* musb: make initial HNP roleswitch work (v2)David Brownell2009-06-16
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* musb: otg timer cleanupDavid Brownell2009-06-16
| | | | | | | | | | | | | | | | | 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.

* musb: proper hookup to transceiver driversDavid Brownell2009-06-16
| | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | 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.

* musb_host: simplify check for active URBSergei Shtylyov2009-06-16
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

* musb_gadget: fix unhandled endpoint 0 IRQsSergei Shtylyov2009-06-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

The interface blacklisting is implemented in sierra driver per device. Each device in need of a blacklist has a static information array kept in the driver. This array contains the interface numbers that are blacklisted. The pointer for each blacklist array and the length of that blacklist are 'bundled' in data structure sierra_iface_info. A pointer to this information is set in id_table when the device is added to the id_table. The following is summary of changes we have made to sierra.c driver in this patch dealing with interface blacklisting support: - Added data structure sierra_iface_info and function is_blacklisted() to support blacklisting - Modified sierra_probe() to handle blacklisted interfaces accordingly - Improved comments in id_table - Added new device in id_table with blacklist interface support Signed-off-by: Elina Pasheva <epasheva@sierrawireless.com> Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

This will save memory especially in the case of using composite devices. - The code has been re-organized and functionality has been extracted from sierra_startup(), sierra_shutdown(), sierra_open(), sierra_close() and added in helper functions sierra_release_urb(), sierra_stop_rx_urbs(), sierra_submit_rx_urbs() and sierra_setup_urb() - Added function sierra_release_urb() to free an urb and its transfer buffer. - Removed unecessary include file reference and comment. - Added function sierra_stop_rx_urbs() that takes care of the release of receive and interrupt urbs. This function is to be called by sierra_close() whenever an interface is de-activated. - Added new function sierra_submit_rx_urbs() that handles the submission of receive urbs and interrupt urbs (if any) during the interface activation. This function is to be called by sierra_open(). Added a second parameter to pass the memory allocation (as suggested by Oliver Neukum) so that this function can be used in post_reset() and resume(). - Added new function sierra_setup_urb() that contains the functionality to allocate an urb, fill bulk urb using the supplied memory allocation flag and release urb upon error. Added parameter so that the caller pass the memory allocation flag for flexibility. - Moved sierra_close() before sierra_open() to resolve dependencies introduced by the code reorganization. - Modified sierra_close() to call sierra_stop_rx_urbs() and sierra_release_urb() functions added in previous patch. - Modified sierra_open() to call sierra_setup_urb() and sierra_submit_rx_urbs() functions; note urbs are allocated and submitted for each activated interface. - Modified sierra_startup() so that allocation of urbs happens whenever an interface is activated (urb allocation is moved to sierra_open()). - Modified sierra_shutdown() so that urbs are freed whenever an interface is de-activated (urb freeing moved to sierra_close() as shown in previous patch from the series) - Removed unecessary data structure from sierra_port_private_data - Suppress an entry in logs by not re-submitting an urb when usb_submit_urb() returns -EPERM, as this shows that usb_kill_urb() is running (as suggested by Oliver Neukum) Signed-off-by: Elina Pasheva <epasheva@sierrawireless.com> Signed-off-by: Alan Cox <alan.cox@linux.intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

We keep track of and respect the sysfs value for non-low-latency cases. In theory we could do smart stuff with VTIME and the like but this seems of questionable worth.

This patch removes this incorrect assumption, and uses request code definitions based on the updated GPL driver from SiLabs. This modification is needed before extended functionality such as GPIO on CP2103 can be supported.

A larger patch (f7e7aa585) a few days after this one added the same line to the Makefile, but in a different place. While it'd be more correct to revert that one, it's easier to revert this one because this is a one-liner.
