* i2c: Allow i2c_add_numbered_adapter() to assign a bus idGrant Likely2011-07-251-5/+2
| | | | | | | | | | Currently, if an i2c bus driver supports both static and dynamic bus ids, it needs to choose between calling i2c_add_numbered_adapter() and i2c_add_adapter(). This patch makes i2c_add_numbered_adapter() redirect to i2c_add_adapter() if the requested bus id is -1.

Commit 925bb9c6 aka ("of/i2c: Fix module load order issue caused by of_i2c.c) moved the of_i2c_register_devices() function from the i2c core back to the drivers.

* i2c-pxa2xx: Add PCI support for PXA I2C controllerSebastian Andrzej Siewior2011-03-211-3/+24
| | | | | | | | | | | | | | | | The Sodaville I2C controller is almost the same as found on PXA2xx. The difference: - the register are at a different offset - no slave support The PCI probe code adds three platform devices which are probed then by the platform code. The X86 part also adds dummy clock defines because we don't have HW clock support.

* ARM: pxa2xx: reorganize I2C filesSebastian Andrzej Siewior2011-03-211-1/+1
| | | | | | | | | | | | | | | | | This patch moves the platform data definition from arch/arm/plat-pxa/include/plat/i2c.h to include/linux/i2c/pxa-i2c.h so it can be accessed from x86 the same way as on ARM. This change should make no functional change to the PXA code. The move is verified by building the following defconfigs: cm_x2xx_defconfig corgi_defconfig em_x270_defconfig ezx_defconfig imote2_defconfig pxa3xx_defconfig spitz_defconfig zeus_defconfig raumfeld_defconfig magician_defconfig mmp2_defconfig pxa168_defconfig pxa910_defconfig Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Dirk Brandewie <dirk.brandewie@gmail.com> Signed-off-by: Ben Dooks <ben-linux@fluff.org>

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* i2c-pxa: Fix adapter numberJean Delvare2007-09-091-1/+1
| | | | | | | | It turns out that platform_device.id is a "u32" so testing it for being nonnegative is useless when setting up an i2c adapte. Instead, do what the platform_bus code does and test it against the value "-1". Signed-off-by: Jean Delvare <khali@linux-fr.org>

* [ARM] 4403/1: Make the PXA-I2C driver work with lockdep validatorEnrico Scholz2007-05-261-14/+9
| | | | | | | | | | | | | | | | | | | | | | Using lockdep validator causes warnings like INFO: trying to register non-static key. the code is fine but needs lockdep annotation. turning off the locking correctness validator.

This patch removes a static pxa_i2c structure which was used only as a source for this memcpy() operation. Instead of, members and the spinlock will be initialized manually.
