usb: dwc3: gadget: fix pending isoc handling

2012-09-06T16:52:30Z

If xfernotready is received and there is no request in request_list then REQUEST_PENDING flag must be set, so that next request in ep queue is executed. In case of isoc transfer, if xfernotready is already elapsed and even first request has not been queued to request_list, then issue END TRANSFER, so that you can receive xfernotready again and can have notion of current microframe.

usb: dwc3: core: fix incorrect usage of resource pointer

2012-09-06T16:52:28Z

Populate the resources for xhci afresh instead of directly using the *struct resource* of core. *resource* structure has parent, sibling, child pointers which should be filled only by resource API's. By directly using the *resource* pointer of core in xhci, these parent, sibling, child pointers are already populated even before *platform_device_add* causing side effects.

usb: dwc3: ep0: correct cache sync issue in case of ep0_bounced

2012-09-06T16:52:24Z

In case of ep0 out, if length is not aligned to maxpacket size then we use dwc->ep_bounce_addr for dma transfer and not request->dma. Since, we have alreday done memcpy from dwc->ep0_bounce to request->buf, so we do not need to issue cache sync function. In fact, cache sync function will bring wrong data in request->buf from request->dma in this scenario. So, cache sync function must not be executed in case of ep0 bounced.

Merge tag 'dwc3-for-v3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next

2012-07-05T22:15:38Z

usb: dwc3: patches for v3.6 merge window lots of changes for the dwc3 driver which will make the driver a lot more stable and some changes which are just cosmetic. The bulk of changes is related to mis-defined macros which were never used before, some fixes to error path which e.g. prevent the driver from initiating two transfer on ep0out in case of stall, some fixes to request dequeueing and the End Transfer Command. We have some changes to U1/U2 handling where we were enabling those transtions at the wrong spot (though we haven't seen a problem from that as of today). A few patches will make it easier to add support for newer releases of the core by adding definitions for new registers and changing the code to act accordingly when certain revisions are detected. There's also the usual comestic changes to make the driver easier to maintain and make it easier for new- comers to understand the driver. Also one patch fixing a double inclusion of a header.

usb: gadget: patches for v3.6 merge window This is quite a big pull request and contains patches all over the place. omap_udc is now a bit cleaner after removing omap2 support, fixing some checkpatch.pl warnings and errors, switching over to generic map/unmap routines and preventing a NULL pointer de-reference. s3c-hsotg has been switched over to devm_* API, got some locking fixes and improvements and it also got an implementation for the pullup() method. the mass storage gadgets changed default value of the removable parameter, dropped some unused options and made "file" and "ro" module_parameters read-only in some cases. ffs function got support for HID descriptor. Some UDCs have been converted to clk_prepare_enable() and clk_disable_unprepare(). Marvell now got support for its USB3 controller in mainline after introducing its mv_u3d_core.c driver.

usb: dwc3: return error in case of run/stop timeout

2012-07-02T07:04:02Z

Although timeout has never been experienced, still to make it meaningful, its better to return error if it ever occurs. Signed-off-by: Pratyush Anand Signed-off-by: Felipe Balbi

usb: dwc3: enable ACCEPT{U1,U2}ENA when SetConfiguration received

2012-07-02T07:03:55Z

As per databook, ACCEPT{U1,U2}ENA bits should be set after receiving SetConfiguration Command. Signed-off-by: Pratyush Anand Signed-off-by: Felipe Balbi

usb: dwc3: no need to clear INIT{U1,U2}ENA bits

2012-07-02T07:03:15Z

as per databook, these bits are cleared by hardware on each USB reset, so no need to clear it explicitly by software in reset ISR. Signed-off-by: Pratyush Anand Signed-off-by: Felipe Balbi

usb: dwc3: keep default hird threshold value as 4b1100

2012-07-02T07:02:34Z

as per data book any HIRD threshold value greater than 4b1100 is invalid. So set the maximum valid value as default values. Signed-off-by: Pratyush Anand Signed-off-by: Felipe Balbi

usb: dwc3: correct set_halt implementation for ep0

2012-07-02T07:02:07Z

set_halt for ep0 is called to stall a deferred control responses by the gadget. We already have a function to stall default control endpoint. This patch points set_halt for ep0 to the already available function. Signed-off-by: Pratyush Anand Signed-off-by: Michel Sanches Signed-off-by: Felipe Balbi
