This moves <linux/usb_ch9.h> to <linux/usb/ch9.h> to reduce some of the clutter of usb header files. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-01-05USB: omap_udc build fixes (sync with linux-omap)David Brownell1-53/+192
Resync the omap_udc driver with the latest from the Linux-OMAP tree. Changes include DMA API updates (it builds again!), clock/pm updates, minor bugfixes, whitespace. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-12-20USB: gadget driver unbind() is optional; section fixes; miscDavid Brownell1-5/+8
Allow gadget drivers to omit the unbind() method. When they're statically linked, that's an appropriate memory saving tweak. Similarly, provide consistent/simpler handling for a should-not-happen error case: removing a peripheral controller driver when a gadget driver is still loaded. Such code dates back to early versions of the first implementation of the gadget API, and has never been triggered. Includes relevant section annotation fixs for gmidi.c, file_storage.c, and serial.c; we don't yet have an "init or exit" annotation. Also some whitespace fixes in gmidi.c (space at EOL, before tabs, etc). Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells1-6/+3
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

2006-03-20[PATCH] USB: kzalloc() conversion in drivers/usb/gadgetEric Sesterhenn1-4/+2
this patch converts drivers/usb to kzalloc usage. Compile tested with allyes config. I think there was a bug in drivers/usb/gadget/inode.c because it used sizeof(*data) for the kmalloc() and sizeof(data) for the memset(), since sizeof(data) just returns the size for a pointer.

2005-10-28[PATCH] add usb transceiver set_suspend() methodJuha Yrj?l?1-0/+4
When a USB device is put into suspend mode, the current drawn from VBUS has to be less than 500 uA. Some transceivers need to be put into a special power-saving mode to accomplish this, and won't have a separate OTG driver handling that. This adds a suspend method to the "otg_transceiver" struct -- misnamed, it's not only for OTG -- and calls it from the OMAP UDC driver.

2005-10-28[PATCH] omap_udc dma off-by-one fixDavid Brownell1-3/+5
The change to make DMA work two bytes at a time omitted an important tweak that affects the file_storage gadget: it needs to recognize when the host writes an odd number of bytes. (The network layer ignores such extra bytes.) This patch resolves that issue by checking the relevant bit and adjusting the rx byte count, so that for example a legal 13 byte request doesn't morph into an illegal 14 byte one any more.

2005-10-28[PATCH] DRIVER MODEL: Get rid of the obsolete tri-level suspend/resume callbacksRussell King1-7/+2
In PM v1, all devices were called at SUSPEND_DISABLE level. Then all devices were called at SUSPEND_SAVE_STATE level, and finally SUSPEND_POWER_DOWN level. However, with PM v2, to maintain compatibility for platform devices, I arranged for the PM v2 suspend/resume callbacks to call the old PM v1 suspend/resume callbacks three times with each level in order so that existing drivers continued to work. Since this is obsolete infrastructure which is no longer necessary, we can remove it. Here's an (untested) patch to do exactly that.

2005-06-27[PATCH] USB: more omap_udc updates (dma and omap1710)David Brownell1-40/+113
More omap_udc updates: * OMAP 1710 updates - new UDC bit for clearing endpoint toggle, affecting CLEAR_HALT - new OTG bits affecting wakeup * Fix the bug Vladimir noted, that IN-DMA transfer code path kicks in for under 1024 bytes (not "up to 1024 bytes") * Handle transceiver setup more intelligently - use transceiver whenever one's available; this can be handy for GPIO based, loopback, or transceiverless configs - cleanup correctly after the "unrecognized HMC" case * DMA performance tweaks - allow burst/pack for memory access - use 16 bit DMA access most of the time on TIPB * Add workarounds for some DMA errata (not observed "in the wild"): - DMA CSAC/CDAC reads returning zero - RX/TX DMA config registers bit 12 always reads as zero (TI patch) * More "sparse" warnings removed, notably "changing" the SETUP packet to return data in USB byteorder (an API change, null effect on OMAP except for these warnings).

2005-06-27[PATCH] USB: omap_udc updates (mostly cleanups)David Brownell1-57/+93
Various USB patches, mostly for portability: - Fifo mode 1 didn't work previously (oopsed), so now it's fixed and (why not) defines even more endpoints for composite devices. - OMAP 1710 doesn't have an internal transceiver. - Small PM update: if the USB link is suspended, don't disconnect on entry to deep sleep. - Be more correct about handling zero length control reads. OMAP seems to mis-handle that protocol peculiarity though; best avoided. - Platform device resources (for UDC and OTG controllers) now use physical addresses, so /proc/iomem is more consistent. - Minor cleanups, notably (by volume) for "sparse" NULL warnings.

2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+2872
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
