I'm ignoring the USB serial stuff here. Most of the "gadget_chips.h" symbols are not dead, they're just constants reserved for drivers that are currently not in the kernel.org tree. The role is much the same as symbols generated from the arch/arm/tools/mach-types file. That said, I think Montavista has a few drivers it's not even tried to push, ditto handhelds.org ... see comments below. Thanks for sanity checking this stuff, by the way. > ========== MACH_OMAP_H4_OTG ========== > drivers/usb/gadget/omap_udc.c:2159:#ifndef CONFIG_MACH_OMAP_H4_OTG This is set in some of the OMAP patches that haven't yet merged. > ========== USB_GADGETFS_PXA2XX ========== > drivers/usb/gadget/inode.c:1508:#ifndef CONFIG_USB_GADGETFS_PXA2XX Hmm... should be "_GADGET_" not "_GADGETFS_".

Freescale's support for IMX family seems kind of spotty. I'm sure I saw a driver for this at one point, but it's clearly not been submitted and I don't know where it'd be now. > ========== USB_GADGET_MPC8272 ========== > drivers/usb/gadget/gadget_chips.h:122:#ifdef CONFIG_USB_GADGET_MPC8272 ISTR this is a Montavista driver; currently available with one of their kernels, but not yet pushed upstream. > ========== USB_GADGET_MQ11XX ========== > drivers/usb/gadget/gadget_chips.h:54:#ifdef CONFIG_USB_GADGET_MQ11XX > drivers/usb/gadget/ether.c:249:#ifdef CONFIG_USB_GADGET_MQ11XX Last I heard, this driver was sitting in the hh.org tree ... > ========== USB_GADGET_MUSB_HDRC ========== > drivers/usb/gadget/gadget_chips.h:116:#ifdef CONFIG_USB_GADGET_MUSB_HDRC > drivers/usb/gadget/ether.c:277:#ifdef CONFIG_USB_GADGET_MUSB_HDRC This is in the OMAP tree; probably nearly ready to go upstream.

It's one of the few discrete (non-SOC) controllers I've come across which doesn't use PCI and isn't OTG-capable; seems that most vendors just want to integrate USB into their SOCs. > ========== USB_GADGET_PXA27X ========== > drivers/usb/gadget/gadget_chips.h:72:#ifdef CONFIG_USB_GADGET_PXA27X > drivers/usb/gadget/ether.c:261:#ifdef CONFIG_USB_GADGET_PXA27X Various versions of this are available. So far as I know, none is yet mergeable ... I've suggested that folk just stop trying to use the broken-by-design config management stuff and instead use it just like the PXA 25x silicon. A long and painful saga. > ========== USB_GADGET_S3C2410 ========== > drivers/usb/gadget/gadget_chips.h:84:#ifdef CONFIG_USB_GADGET_S3C2410 > drivers/usb/gadget/ether.c:265:#ifdef CONFIG_USB_GADGET_S3C2410 Recently submitted ... the driver's been in use since 2005 or so. So I'm glad to see that it's starting to move upstream! > ========== USB_GADGET_SA1100 ========== > drivers/usb/gadget/gadget_chips.h:42:#ifdef CONFIG_USB_GADGET_SA1100 > drivers/usb/gadget/ether.c:300:#ifdef CONFIG_USB_GADGET_SA1100 I don't think that driver has been finished; the hardware is excessively buggy, and most of its users are on 2.4 still. There was one partial success report on 2.6; having this work would let the original Zaurus models upgrade to 2.6 kernels. > ========== USB_GADGET_SH ========== > drivers/usb/gadget/ether.c:296:#ifdef CONFIG_USB_GADGET_SH > ========== USB_GADGET_SUPERH ========== > drivers/usb/gadget/gadget_chips.h:36:#ifdef CONFIG_USB_GADGET_SUPERH The _SH is a bug, should be SUPERH. Not sure what happend to the SH3 UDC ... it seems not to have been ported from 2.4 kernel yet. (And I could be wrong, but I think SH3 is kind of old now.) - Dave - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
