* USB: musb: add Blackfin specific configuration to MUSBBryan Wu2009-01-071-15/+7
| | | | | | | | | | | | | Some config registers are not avaiable in Blackfin, we have to comment them out. v1-v2: - remove Blackfin specific header file - add Blackfin register version to musb_regs.h header file Signed-off-by: Bryan Wu <cooloney@kernel.org> Signed-off-by: Felipe Balbi <felipe.balbi@nokia.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* USB: musb: host side diagnostics tweaksDavid Brownell2009-01-071-9/+14
| | | | | | | | | | | | | | | | | | | | | | | Random host-side MUSB updates, mostly relating to better diagnostics: + Improve diagnostics on host side: - tx flush fifo: * Avoid hundreds of duplicate TX FIFONOTEMPTY messages * make "Can't flush TX fifo" a warning, and say which endpoint - giveback: * use correct status code * show completion function name not just URB pointer - Fix annoying "1 bytes" (should be "1 byte") + Be more consistent about failing init of unusable fifo_mode It's not clear why that "can't flush TX fifo" message appears, though it might relate to disconnection; I see it not infrequently Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Felipe Balbi <felipe.balbi@nokia.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* usb: musb: fix BULK request on different available endpointsAjay Kumar Gupta2008-11-131-37/+45
| | | | | | | | | | | | | | | | | | | Fixes co-working issue of usb serial device with usb/net devices while oter endpoints are free and can be used.This patch implements the policy that if endpoint resources are available then different BULK request goes to different endpoint otherwise they are multiplexed to one reserved endpoint as currently done. Switch statement case is reordered in musb_giveback() to take care of bulk request both in multiplex scenario and otherwise. NAK limit scheme has to be added for multiplexed BULK request scenario to avoid endpoint starvation due to usb/net devices.

* usb: musb: Fix for isochronous IN transferAjay Kumar Gupta2008-11-131-20/+57
| | | | | | | | | | | Fixes blurred capture images in dma mode. Isochronous error field in urb and source data buffer pointer were not updated properly in dma mode.

* usb: musb_hdrc build fixesDavid Brownell2008-10-171-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | Minor musb_hdrc updates: - so it'll build on DaVinci, given relevant platform updates; * remove support for an un-shipped OTG prototype * rely on gpiolib framework conversion for the I2C GPIOs * the <asm/arch/hdrc_cnf.h> mechanism has been removed - catch comments up to the recent removal of the per-SOC header with the silicon configuration data; - and remove two inappropriate "inline" declarations which just bloat host side code. There are still some more <asm/arch/XYZ.h> ==> <mach/XYZ.h> changes needed in this driver, catching up to the relocation of most of the include/asm-arm/arch-* contents.

* OMAP:MUSB: Corrects urb unlink function pathAjay Kumar Gupta2008-10-171-2/+5
| | | | | | | | | | | | | | | Fixes kernel panic while ISO IN transfer is aborted.Replaced usb_hcd_unlink_urb_from_ep() from musb_giveback() to __musb_giveback() to make sure urb is unlinked before giveback when __musb_giveback() is called from musb_urb_dequeue(). Acquired musb->lock() before usb_hcd_unlink_urb_from_ep() within in enqueue path.

* OMAP:MUSB: Fixes the TT programming.Ajay Kumar Gupta2008-10-171-1/+5
| | | | | | | | | | | Fixes enumeration failures when a USB device attached to a LS hub is connected to OMAP EVM via HS hub. This is fixed by correctly programming hub address register in enqueue path.
