2007-02-07USB serial: add dynamic id support to usb-serial coreGreg Kroah-Hartman
Thanks to Johannes Hölzl <johannes.hoelzl@gmx.de> for fixing a few things and getting it all working properly. This adds support for dynamic usb ids to the usb serial core. The file "new_id" will show up under the usb serial driver, not the usb driver associated with the usb-serial driver (yeah, it can be a bit confusing at first glance...) This patch also modifies the USB core to allow the usb-serial core to reuse much of the dynamic id logic.

2007-02-07ohci: Add support for OHCI controller on the of_platform busSylvain Munaut

2007-02-07ohci: Rework bus glue integration to allow several at onceSylvain Munaut
The previous model had the module_init & module_exit function in the bus glue .c files themselves. That's a problem if several glues need to be selected at once and the driver is built has module. This case is quite common in embedded system where you want to handle both the integrated ohci controller and some extra controller on PCI. The ohci-hcd.c file now provide the module_init & module_exit and appropriate driver registering/unregistering is done conditionally, using #ifdefs.

2007-02-07rndis_host learns ActiveSync basicsOle Andre Vadla Ravnas
Windows Mobile 5 based devices described as supporting "ActiveSync": - Speak RNDIS but lack the CDC and union descriptors. This patch updates the cdc ethernet code to fake ACM descriptors we need. - Require RNDIS_MSG_QUERY messages to include a buffer of the size the response should generate. This patch updates the rndis host code to pass this will-be-ignored data. The resulting RNDIS host code has been reported to work with several WM5 based devices. (Note that a fancier patch is available at synce.sf.net.) Some bugfixes, affecting not just ActiveSync: (a) when cleaning up after RNDS init fails, scrub the second interface just like cdc_ether does, so disconnect won't oops. (b) handle peripherals that use the pad-to-end-of-packet option; some devices can't talk to us if that option doesn't work. (c) when choosing configurations, don't forget about an RNDIS config just because the RNDIS driver is dynamically linked. Cleanup, streamlining, bugfixes, Kconfig, and matching hub driver update. Also for paranoia's sake, refuse to talk to something that looks like a real modem instead of RNDIS.

2007-02-07USB: ethernet gadget interop with MCCI Windows driverDavid Brownell
It turns out that minor tweaks to the "CDC Subset" support in the Ethernet gadget driver, just updating a config descriptor, let it be automagically recognized by a Windows driver supported by MCCI. This patch adds those descriptors, so systems using PXA 255 processors (like Gumstix etc) can interop with those commercial MS-Windows drivers. This is a Good Thing since Microsoft's RNDIS code has bugginess issues, which are unfortunately compounded by "won't fix" issues as well as "the published specs are incomplete and wrong" issues. Being able to talk to the MCCI driver gives Windows users another connectivity option. (MCCI also has CDC Ethernet drivers, which can help most non-PXA processors.)

2007-02-07USB: Implement support for EHCI with big endian MMIOBenjamin Herrenschmidt
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.

This also moves the quirks to reset() as suggested by the comment in there. This is necessary as we need to have the endian properly set before we try to init the controller.

2007-02-05[S390] Convert memory detection into C code.Heiko Carstens
Hopefully this will make it more maintainable and less error prone. Code makes use of search_exception_tables(). Since it calls this function before the kernel exeception table is sorted, there is an early call to sort_main_extable(). This way it's easy to use the already present infrastructure of fixup sections. Also this would allows to easily convert the rest of head[31|64].S into C code.

2007-02-05[S390] ETR support.Martin Schwidefsky
This patch adds support for clock synchronization to an external time reference (ETR). The external time reference sends an oscillator signal and a synchronization signal every 2^20 microseconds to keep the TOD clocks of all connected servers in sync. For availability two ETR units can be connected to a machine. If the clock deviates for more than the sync-check tolerance all cpus get a machine check that indicates that the clock is out of sync. For the lovely details how to get the clock back in sync see the code below. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

The initialization of the dasd_eer code is one of the last steps of the dasd driver initialization. When initialization fails in one of the earlier steps, the dasd_exit function is called to clean up what has been done so far. So the dasd_eer_exit function may be called, although the dasd_eer_init function wasn't called before and dasd_eer_exit tries to unregister a misc device that wasn't registered, which results in a BUG. Make sure that dasd_eer_exit can be called without initialization.
