2008-05-02USB: Add the USB 2.0 extension descriptor.Sarah Sharp1-1/+11
This device descriptor was added by the recent USB Link Power Management (LPM) ECN. It indicates whether the USB device supports LPM. This descriptor is grouped under a Binary Device Object Store (BOS) descriptor. Update the BOS comments to indicate any USB device (not just wireless USB devices) can implement BOS descriptors.

2008-04-24USB: Standardize inclusion protection and add where missing.Robert P. J. Day1-1/+1
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: Robert P.

2008-04-24USB: defines for USB "Link Power Management" (LPM) ECNDavid Brownell1-3/+11
There's a new PM-related change notice for the USB 2.0 specification called "Link Power Management" (LPM). It defines a new "L1 Suspend" state which resembles the current (L2) suspend state, except that it can be entered and exited much more quickly. It should thus be more useful for runtime PM, even though it doesn't mandate reduced power draw from VBUS. This patch provides the relevant #defines for usbcore. Actually implementing these mechanisms requires host silicon that can generate new USB packets, plus hubs handling some new requests and peripherals which understand the new packets.

2008-04-24USB: add USB_DT_CS_RADIO_CONTROL define to ch9.hGreg Kroah-Hartman1-0/+1
This is needed by the wireless usb developers, and is part of the USB spec. Cc: Inaky Perez-Gonzalez <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
2007-04-27USB: <linux/usb/ch9.h> minor doc updateDavid Brownell1-6/+9
Minor doc update to <linux/usb/ch9.h> ... say where USB_DT_CS_* came from and update the definitions to match how they're derived there. Signed-off-by: David Brownell <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
2007-02-23USB: add rationale on why usb descriptor structures have to be packedInaky Perez-Gonzalez1-4/+18
Add argumentation in defense of using __attribute__((packed)) in USB descriptors authored by Dave Brownell. Necessary as in some cases it seems superfluous. Signed-off-by: Inaky Perez-Gonzalez <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
2007-02-16USB: descriptor structures have to be packedInaky Perez-Gonzalez1-10/+10
usb: descriptor structures have to be packed Many of the Wireless USB decriptors added to usb_ch9.h don't have the __attribute__((packed)) tag, and thus, they don't reflect the wire size. This patch fixes that. Signed-off-by: Inaky Perez-Gonzalez <[email protected]> Signed-off-by: David Brownell <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>

2007-02-07USB: <linux/usb_ch9.h> becomes <linux/usb/ch9.h>David Brownell1-0/+562
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 <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
