* USB: remove dev->power.power_stateAlan Stern2008-04-241-1/+1
| | | | | | | | | | | | | | | | power.power_state is scheduled for removal. This patch (as1053) removes all uses of that field from drivers/usb. Almost all of them were write-only, the most significant exceptions being sl811-hcd.c and u132-hcd.c. Part of this patch was written by Pavel Machek.

* USB: ehci: minor cleanupsDavid Brownell2008-04-241-1/+1
| | | | | | | | | | Minor cleanups to the EHCI code: revision history is what source code repositories should have. Switch to a more standard way to kick in verbose debugging -- don't be EHCI-specific.

* USB: EHCI: add separate IAA watchdog timerAlan Stern2008-02-011-3/+1
| | | | | | | | | | | | | | | | This patch (as1028) was mostly written by David Brownell; I made only a few changes (extra log info and a small bug fix -- which might account for why David's version had to be reverted). It adds a new watchdog timer to the ehci-hcd driver to be used exclusively for detecting lost or missing IAA notifications. Previously a shared timer had been used, which may have led to some problems as reported by Christian Hoffmann.

* USB: convert ehci debug files to use debugfs instead of sysfsTony Jones2008-02-011-40/+187

* USB: EHCI support for big-endian descriptorsStefan Roese2007-07-121-76/+85
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements supports for EHCI controllers whose in-memory data structures are represented in big-endian format. This is needed (unfortunately) for the AMCC PPC440EPx SoC EHCI controller; the EHCI spec doesn't specify little-endian format, although that's what most other implementations use. The guts of the patch are to introduce the hc32 type and change all references from le32 to hc32. All access routines are converted from cpu_to_le32(...) to cpu_to_hc32(ehci, ...) and similar for the other "direction". (This is the same approach used with OHCI.) David fixed: Whitespace fixes; refresh against ehci cpufreq patch; move glue for that PPC driver to the patch adding it; fix free symbol capture bugs in modified "constant" macros; and make "hc32" etc be "le32" unless we really need the BE options, so "sparse" can do some real good.

* USB: Implement support for EHCI with big endian MMIOBenjamin Herrenschmidt2007-02-071-12/+12
| | | | | | | | | | | | | | | | | | This patch implements supports for EHCI controllers whose MMIO registers are big endian and enables that functionality for the Toshiba SCC chip. It does _not_ add support for big endian in-memory data structures as this is not needed for that chip and I hope it will never be. The guts of the patch are to convert readl(...) to ehci_readl(ehci, ...) and similarly for register writes.

* USB: EHCI update VIA workaroundDavid Brownell2006-09-271-3/+1
| | | | | | | | | | | | | | This revamps handling of the hardware "async advance" IRQ, and its watchdog timer. Basically it dis-entangles that important timeout from the others, simplifying the associated state and code to make it more robust. This reportedly improves behavior of EHCI on some systems with VIA chips, and AFAIK won't affect non-VIA hardware. VIA systems need this code to recover from silcon bugs whereby the "async advance" IRQ isn't issued.

* usbcore: trim down usb_bus structureAlan Stern2006-09-271-3/+3
| | | | | | | | | | | | | | | | | | | | | | As part of the ongoing program to flatten out the HCD bus-glue layer, this patch (as771b) eliminates the hcpriv, release, and kref fields from struct usb_bus. hcpriv and release were not being used for anything worthwhile, and kref has been moved into the enclosing usb_hcd structure. Along with those changes, the patch gets rid of usb_bus_get and usb_bus_put, replacing them with usb_get_hcd and usb_put_hcd. The one interesting aspect is that the dev_set_drvdata call was removed from usb_put_hcd, where it clearly doesn't belong. This means the driver private data won't get reset to NULL. It shouldn't cause any problems, since the private data is undefined when no driver is bound. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* [PATCH] swsusp: switch pm_message_t to structPavel Machek2005-09-051-1/+1
| | | | | | | | | | | | | | This adds type-checking to pm_message_t, so that people can't confuse it with int or u32. It also allows us to fix "disk yoyo" during suspend (disk spinning down/up/down).

* [PATCH] USB: ehci: microframe handling fixDavid Brownell2005-08-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | This patch has a one line oops fix, plus related cleanups. - The bugfix uses microframe scheduling data given to the hardware to test "is this a periodic QH", rather than testing for nonzero period. (Prevents an oops by providing the correct answer.) - The cleanup going along with the patch should make it clearer what's going on whenever those bitfields are accessed. The bug came about when, around January, two new kinds of EHCI interrupt scheduling operation were added, involving both the high speed (24 KBytes per millisec) and low/full speed (1-64 bytes per millisec) microframe scheduling. A driver for the Edirol UA-1000 Audio Capture Unit ran into the oops; it used one of the newly supported high speed modes.

Almost all of them involve just changing the second parameter of the suspend() method to a pm_message_t ... the others relate to how the EHCI code walks in-memory data structures.

* Linux-2.6.12-rc2Linus Torvalds2005-04-161-0/+755
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!
