This patch cleans up some of the sierra driver code. Please package this with the other patches in this group as I would like the driver version to reflect their changes as well. Signed-off-by:

the following patch uses 16 write urbs and a writsize of wMaxPacketSize * 20. With this patch I get the maximum througput from my linux system with 20MB/sec read and 15 MB/sec write (full speed 1 MB/sec both) I also deleted the flag URB_NO_FSBR for the writeurbs, because this makes my full speed devices significant slower.

Based on a recent discussion on the Linux USB mailing list, remove the designation of EXPERIMENTAL from some USB gadget entries, and tag some of them as DEVELOPMENT. just for fun, i added a bit of help for gadgetfs, explaining the race condition. Signed-off-by:

I have got a cypress usb-ide bridge and I would like to tune or monitor my disk with tools like hdparm, hddtemp or smartctl. My controller support a way to send raw ATA command to the disk with something call atacb (see http://download.cypress.com.edgesuite.net/design_resources/datasheets/contents/cy7c68300c_8.pdf). Atacb support can be added for each application, but there is some disadvantages : - all application need to be patched - A race is possible if there other accesses, because the emulation can be split in 2 atacb scsi transactions. One for sending the command, one for reading the register (if ck_cond is set). I have implemented the emulation in usb-storage with a special proto_handler, and an unsual entry. Signed-off-by:

For the header files in include/linux/usb, add missing multiple inclusion protection and standardize what's already there. The apparent standards: * macro name of __LINUX_USB_headerfile_H * inclusion protection placed after leading comment block * macro name added as a comment on the final #endif * any obvious trivial whitespace cleanup associated with the above Signed-off-by:

The the err() / info() / warn() macros in usb.h inserted __FILE__ at the beginning of the message, which expands to the complete pathname of the source file within the kernel tree, frequently taking up half of an 80 character screen line before the actual message even begins. Use the module name instead. Signed-off-by:

Some EHCI fault paths with large control transfers aren't coded. Avoid problems by rejecting transfers that may need two qTDs (16+ KB). This is mostly paranoia; even 4 KB transfers are rare, and most HCDs use lower limits (so it's unlikely anyone would ever try such a thing). Signed-off-by:

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. Signed-off-by:

The ipaq module supports devices with one endpoint only. Some devices, e.g. Yakumo Delta 300, have more than one endpoint. This patch fixes support for devices having up to 2 endpoints which used to work on older kernel versions. Signed-off-by:

It was pointed out that we found and fixed the cause of the "bogus" fatal IRQ reports some time ago ... this patch removes the code which was working around that bug ("status" got clobbered), and a comment which needlessly confused folk reading this code. This also includes a minor cleanup to the code which fixed that bug. Signed-off-by: -

This provides better support for USB "Embedded Host" functionality, which is a subset of the USB OTG options: * External hub support can be disabled; * USB peripherals not whitelisted in "otg_whitelist.h" will be rejected during enumeration. These options can allow some savings in software and support. Signed-off-by:

The cypress app note for the M8 states that for the USB low speed version of the part, throughput is effectively limited to 800 bytes/sec. So if we were to try a faster baud rate in such cases then we risk overrun errors on receive. Best to just identify this case and limit the rate to 4800 baud or less (by ignoring any request to set a faster rate). The old baud rate setting code was somewhat fragile; this change also hopefully makes it easier in the future to better checking / limiting. Signed-off-by:

Remove a NULL check in cypress_m8; the check is useless in this context because it is referenced earlier in the same code path thus the kernel would be oops'ed before reaching this point anyway. (And it's really pointless here anyway; if this pointer somehow is NULL the driver is going to have serious problems in many other places.) Signed-off-by:

Earthmate LT-20 devices (both "old" and "new" versions) can't tolerate a GET_CONFIG command. The original Earthmate has no trouble with this. Presumably other non-Earthmate devices are still OK as well. This change disables the use of GET_CONFIG for cases where it is known not to work. Signed-off-by:

cypress_m8: Packet format is separate from characteristic size The Cypress app note states that when using an 8 byte packet buffer size that the packet format is modified (to be more compact). However I have since discovered that newer DeLorme Earthmate LT-20 devices (those that are low speed USB with 8 byte packet size) STILL use the format that is really supposed to correspond to 32 byte packets. Further confusing things is the subsequent discovery that there are actually two different types of LT-20 - older LT-20's use 32 byte packets which is probably why this issue wasn't originally encountered. The solution here is to flag the packet format separately from the buffer size. Then at initialization time, identify the correct combination and set it up. This is a critical fix for anyone with a newer LT-20. Older devices and non-Earthmate devices should remain unaffected by this change. (If other devices behave in this, uh, unexpected manner, it's now just a simple 1 line change to fix them as well (change the pkt_fmt member for that device). Default behavior with this patch is still to drive the format as per the app-note; of course for Earthmate devices this is overridden. Signed-off-by:

cypress_m8: Feature buffer fixes From: Mike Isely <isely@pobox.com> Don't hardcode the feature buffer size; use sizeof() instead. That way we can easily specify the size in a single spot. Speaking of the feature buffer size, the Cypress app note (and further testing with a DeLorme Earthmate) suggests that this size should be 5 not 8 bytes. Signed-off-by:
