2012-06-26USB: FHCI: Reusing QUICC Engine USB Controller registers from immap_qe.hGuilherme Maciel Ferreira1-16/+16
The struct fhci_regs (in drivers/usb/host/fhci.h) is basically a redefinition of the struct qe_usb_ctlr (in arch/powerpc/include/asm/immap_qe.h). The qe_usb_ctlr struct is preferrable once it uses accurately the registers' names found in the Freescale's QUICC Engine Block Reference Manuals (QEIWRM.pdf Rev.4.4 Chapter 19 for MPC836xE series and MPC8323ERM.pdf Rev.2 Chapter 36 for MPC832xE series), making easier to map the FHCI device driver to the hardware manual. Also, as the FHCI driver uses the USB Controller registers, the name qe_usb_ctlr is a more precise representation of the hardware than fhci_regs.

2011-11-28usb: convert drivers/usb/* to use module_platform_driver()Axel Lin1-11/+1
This patch converts the drivers in drivers/usb/* to use the module_platform_driver() macro which makes the code smaller and a bit simpler.

2010-05-22of: Remove duplicate fields from of_platform_driverGrant Likely1-2/+5
.name, .match_table and .owner are duplicated in both of_platform_driver and device_driver. This patch is a removes the extra copies from struct of_platform_driver and converts all users to the device_driver members. This patch is a pretty mechanical change. The usage model doesn't change and if any drivers have been missed, or if anything has been fixed up incorrectly, then it will fail with a compile time error, and the fixup will be trivial. This patch looks big and scary because it touches so many files, but it should be pretty safe.

2010-05-20USB: make hcd.h public (drivers dependency)Eric Lescouet1-1/+1
The usbcore headers: hcd.h and hub.h are shared between usbcore, HCDs and a couple of other drivers (e.g. USBIP modules). So, it makes sense to move them into a more public location and to cleanup dependency of those modules on kernel internal headers. This patch moves hcd.h from drivers/usb/core into include/linux/usb/ Signed-of-by: Eric Lescouet <eric@lescouet.org> Cc: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.hTejun Heo1-0/+1
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.

2009-01-27USB: Driver for Freescale QUICC Engine USB Host ControllerAnton Vorontsov1-0/+836
This patch adds support for the FHCI USB controller, as found in the Freescale MPC836x and MPC832x processors. It can support Full or Low speed modes. Quite a lot the hardware is doing by itself (SOF generation, CRC generation and checking), though scheduling and retransmission is on software's shoulders. This controller does not integrate the root hub, so this driver also fakes one-port hub. External hub is required to support more than one device.
