Clean up the serial gadget, using newer APIs and conventions: - gadget_is_dualspeed() and gadget_is_otg() ... #ifdef removal - Remove many now-needless #includes - Use the DEBUG and VERBOSE_DEBUG conventions; turned up a bug in the original debug messaging - Various whitespace fixes. This gave only a minor object code shrinkage, but the source looks much cleaner in various places. Signed-off-by:

Clean up the ethernet gadget, using newer APIs and conventions: - gadget_is_dualspeed() and gadget_is_otg() ... #ifdef removal - Remove many now-needless #includes - Use the VERBOSE_DEBUG convention - Minor whitespace fixes. - Fix a warning from "sparse". Surprisingly, this saved about 2K of code (16%) on a fullspeed-only ARMv4 platform. I'm bit puzzled by that (it's so much!), but approve of the result. Signed-off-by:

This adds two small inlines to the gadget stack, which will often evaluate to compile-time constants. That can help shrink object code and remove #ifdeffery. - gadget_is_dualspeed(), currently always a compile-time constant (depending on which controller is selected). - gadget_is_otg(), usually a compile time "false", but this is a runtime test if the platform enables OTG (since it's reasonable to populate boards with different USB sockets). It also updates two peripheral controller drivers to use these: - fsl_usb2_udc, mostly OTG-related bugfixes: non-OTG devices must follow the rules about drawing VBUS power, and OTG ones need to reject invalid SET_FEATURE requests. - omap_udc, just scrubbing a bit of #ifdeffery. And also gadgetfs, which lost some #ifdefs and moved to a more standard handling of DEBUG and VERBOSE_DEBUG. The main benefits come from patches which will follow. Signed-off-by:

This patch (as953) separates out three key portions from usb_hcd_submit_urb(), usb_hcd_unlink_urb(), and usb_hcd_giveback_urb() and puts them in separate functions of their own. In the next patch, these functions will be called directly by host controller drivers while holding their private spinlocks, which will remove the possibility of some unpleasant races. The code responsible for mapping and unmapping DMA buffers is also placed into a couple of separate subroutines, for the sake of cleanliness and consistency. Signed-off-by:

This patch (as952) adjusts the spinlock usage in the root-hub emulation part of usbcore, to make it match more closely the pattern used by regular host controller drivers. To wit: The private lock (usb_hcd_root_hub_lock) is held throughout the important parts, and it is dropped temporarily without re-enabling interrupts around the call to usb_hcd_giveback_urb(). A nice side effect is that the code now avoids calling local_irq_save(), thereby becoming more RT-friendly. Signed-off-by:

This patch (as951) cleans up a few loose ends from earlier patches. Redundant checks for non-NULL urb->dev are removed, as are checks of urb->dev->bus (which can never be NULL). Conversely, a check for non-NULL urb->ep is added to the unlink paths. A homegrown round-down-to-power-of-2 loop is simplified by using the ilog2 routine. The comparison in usb_urb_dir_in() is made more transparent. Signed-off-by:

This patch (as948) removes most of the references to urb->pipe from the usbfs routines in devio.c. The one tricky aspect is in snoop_urb(), which can be called before the URB is submitted and which uses usb_urb_dir_in(). For this to work properly, the URB's direction flag must be set manually in proc_do_submiturb(). The patch also fixes a minor bug; the wValue, wIndex, and wLength fields were snooped in proc_do_submiturb() without conversion from le16 to CPU-byte-ordering. Signed-off-by:

This patch (as947) changes the device initialization and enumeration code in hub.c; now udev->devnum will be set to 0 while the device is being accessed at address 0. Until now this wasn't needed because the address value was passed as part of urb->pipe; without that field the device address must be stored elsewhere. Signed-off-by:

This patch (as946) eliminates many of the uses of urb->pipe in usbcore. Unfortunately there will have to be a significant API change, affecting all USB drivers, before we can remove it entirely. This patch contents itself with changing only the interface to usb_buffer_map_sg() and friends: The pipe argument is replaced with a direction flag. That can be done easily because those routines get used in only one place. Signed-off-by:

This patch (as945) adds a bit to urb->transfer_flags for recording the direction of the URB. The bit is set/cleared automatically in usb_submit_urb() so drivers don't have to worry about it (although as a result, it isn't valid until the URB has been submitted). Inline routines are added for easily checking an URB's direction. They replace calls to usb_pipein in the DMA-mapping parts of hcd.c. For non-control endpoints, the direction is determined directly from the endpoint descriptor. However control endpoints are bi-directional; for them the direction is determined from the bRequestType byte and the wLength value in the setup packet. Signed-off-by:

This patch (as944) adds an explicit "enabled" field to the usb_host_endpoint structure and uses it in place of the current mechanism. This is merely a time-space tradeoff; it makes checking whether URBs may be submitted to an endpoint simpler. The existing mechanism is efficient when converting urb->pipe to an endpoint pointer, but it's not so efficient when urb->ep is used instead. As a side effect, the procedure for enabling an endpoint is now a little more complicated. The ad-hoc inline code in usb.c and hub.c for enabling ep0 is now replaced with calls to usb_enable_endpoint, which is no longer static. Signed-off-by:

This patch (as943) prepares the way for eliminating urb->pipe by introducing an endpoint pointer into struct urb. For now urb->ep is set by usb_submit_urb() from the pipe value; eventually drivers will set it themselves and we will remove urb->pipe completely. The patch also adds new inline routines to retrieve an endpoint descriptor's number and transfer type, essentially as replacements for usb_pipeendpoint and usb_pipetype. usb_submit_urb(), usb_hcd_submit_urb(), and usb_hcd_unlink_urb() are converted to use the new field and new routines. Other parts of usbcore will be converted in later patches. Signed-off-by:

The ZF Micro OHCI controller exhibits unexpected behavior that seems to be related to high load. Under certain conditions, the controller will complete a TD, remove it from the endpoint's queue, and fail to add it to the donelist. This causes the endpoint to appear to stop responding. Worse, if the device is removed while in that state, OHCI will hang while waiting for the orphaned TD to complete. The situation is not recoverable without rebooting. This fix enhances the scope of the existing OHCI_QUIRK_ZFMICRO flag: 1. A watchdog routine periodically scans the OHCI structures to check for orphaned TDs. In these cases the TD is taken back from the controller and completed normally. 2. If a device is removed while the endpoint is hung but before the watchdog catches the situation, any outstanding TDs are taken back from the controller in the 'sanitize' phase. The ohci-hcd driver used to print "INTR_SF lossage" in this situation; this changes it to the universally accurate "ED unlink timeout". Other instances of this message presumably have different root causes. Both this Compaq quirk and a NEC quirk are now properly compiled out for non-PCI builds of this driver.

This patch implements a mode when a printer returns ENOSPC when it runs out of paper. The default remains the same as before. An application which wishes to use this function has to enable it explicitly with an ioctl LPABORT. This is done on a request by our (Fedora) CUPS guy, Tim Waugh. The API is similar enough to the lp0's one that CUPS works with both (but see below), but it's has some differences. Most importantly, the abort mode is persistent in case of lp0: once tunelp was run your cat fill blow up until you reboot or run tunelp again. For usblp, I made it so the abort mode is only in effect as long as device is open. This way you can mix and match CUPS and cat(1) freely and nothing bad happens even if you run out of paper. It is also safer in the face of any unexpected crashes. It has to be noted that mixing LPABORT and O_NONBLOCK is not advised. It probably does not do what you want: instead of returning -ENOSPC it will always return -EAGAIN (because it would otherwise block while waiting for the paper). Applications which use O_NONBLOCK should continue to use LPGETSTATUS like before. Finally, CUPS actually requires patching to take full advantage of this. It has several components; those which invoke LPABORT work, but some of them need the ioctl added. This is completely compatible, you can mix old CUPS and new kernels or vice versa. Signed-off-by:

Make sure and not dump reserved areas of device space. Touching some of these causes machine check exceptions on boards like D-Link DGE-550SX. Coding note, used a complex switch statement rather than bitmap because it is easier to relate the block values to the documentation rather than looking at a encoded bitmask. Signed-off-by:

Currently find_legacy_serial_ports() can find no serial ports on the OPB with flattened device tree. Thus no legacy boot console can be initialized. Just the early udbg console works, which is initialized with udbg_init_44x_as1 on the UART's physical address specified in kernel config. This happens because we look for ns16750 serial devices only and expect opb node to have a device type property. This patch makes it look for ns16550-compatible devices and use of_device_is_compatible() for opb in case device type is not specified. Signed-off-by:
