2010-08-10USB: musb: forward debug mode feature to gadgetstephane duverger
This is a patch for the musb usb controller. It allows forwarding of the debug mode feature to its gadget in order to be able to act as an ehci debug device. This patch has been tested on an IGEPv2 board running a 2.6.35-rc1 kernel.

2010-08-10USB: musb: do not override DMA mode in channel programAnand Gadiyar
There is no reason for the DMA channel program to override the DMA mode passed down by its caller. Use the passed parameter directly, and let the caller handle the decision on which mode is to be used.

2010-08-10USB: convert usb_hcd bitfields into atomic flagsAlan Stern
This patch (as1393) converts several of the single-bit fields in struct usb_hcd to atomic flags. This is for safety's sake; not all CPUs can update bitfield values atomically, and these flags are used in multiple contexts. The flag fields that are set only during registration or removal can remain as they are, since non-atomic accesses at those times will not cause any problems. (Strictly speaking, the authorized_default flag should become atomic as well. I didn't bother with it because it gets changed only via sysfs. It can be done later, if anyone wants.)

2010-06-30USB: musb: Enable the maximum supported burst mode for DMAHema HK
Setting MUSB Burst Mode 3 automatically enables support for lower burst modes (BURST4, BURST8, BURST16 or bursts of unspecified length). There is no need to set these burst modes based on the packet size. Also enable the burst mode for both mode1 and mode0. This is a fix for buggy hardware - having the lower burst modes enabled can potentially cause lockups of the DMA engine used in OMAP2/3/4 chips.

2010-05-20USB: straighten out port feature vs. port status usageAlan Stern
This patch (as1349b) clears up the confusion in many USB host controller drivers between port features and port statuses. In mosty cases it's true that the status bit is in the position given by the corresponding feature value, but that's not always true and it's not guaranteed in the USB spec. There's no functional change, just replacing expressions of the form (1 << USB_PORT_FEAT_x) with USB_PORT_STAT_x, which has the same value.

Commit 18eabe2347ae7a11b3db768695913724166dfb0e introduced DMA buffer ownership. Fix tusb6010 accordingly. To compile, also dummy musb_platform_save and restore functions need to be added. Also change the order of musb_read_fifo() to happen after dma_cache_maint to have the DMA operations completed before moving the remaining unaligned bytes with PIO. The DMA access and PIO touch different areas of the FIFO, so this change only makes the code a bit easier to follow. Tested on n810 and g_ether with variable size ping test. The test seems to fail for some ping sizes, but that seems to be a different problem.

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo
implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

2010-03-19usb: musb: abstract out ULPI_BUSCONTROL register reads/writesMike Frysinger
The USB PHY on current Blackfin processors is a UTMI+ level 2 PHY. However, it has no ULPI support - so there are no registers at all. That means accesses to ULPI_BUSCONTROL have to be abstracted away like other MUSB registers. This fixes building for Blackfin parts again.

2010-03-19usb: musb: Fix compile error for omaps for musb_hdrcTony Lindgren
CONFIG_ARCH_OMAP34XX is now CONFIG_ARCH_OMAP3. But since drivers/usb/musb/omap2430.c use CONFIG_PM for these registers and functions, do the same for the header. Otherwise we get the following for most omap3 defconfigs: drivers/usb/musb/omap2430.c:261: error: expected identifier or '(' before 'do' drivers/usb/musb/omap2430.c:261: error: expected identifier or '(' before 'while' drivers/usb/musb/omap2430.c:268: error: expected identifier or '(' before 'do' drivers/usb/musb/omap2430.c:268: error: expected identifier or '(' before 'while' Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Felipe Balbi <felipe.balbi@nokia.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2010-03-19USB: musb: fix build error introduced by isoc changeSonic Zhang
The recent commit "usb: musb: Fix for isochronous IN transfer" (f82a689fa) seems to have been against an older kernel version. It uses the old style naming of variables. Unfortunately, this breaks building for most MUSB users out there since "bDesiredMode" has been renamed to "desired_mode".
