This patch changes all absolute SYS_XY registers to offsets from the SYS block base, prefixes them with AU1000 to avoid silent failures due to changed addresses, and introduces helper functions to read/write them. No functional changes, comparing assembly of a few select functions shows no differences.

2013-10-30mmc: au1xmmc: Move away from using deprecated APIsUlf Hansson1-6/+1
Suspend and resume of cards are being handled from the protocol layer and consequently the mmc_suspend|resume_host APIs are deprecated. This means we can simplify the suspend|resume callbacks by removing the use of the deprecated APIs.

2013-05-26mmc: remove unnecessary platform_set_drvdata()Jingoo Han1-1/+0
The driver core clears the driver data to NULL after device_release or on probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d (device-core: Ensure drvdata = NULL when no driver is bound). Thus, it is not needed to manually clear the device driver data to NULL.

2010-05-27mmc: remove the "state" argument to mmc_suspend_host()Matt Fleming1-1/+1
Even though many mmc host drivers pass a pm_message_t argument to mmc_suspend_host() that argument isn't used the by MMC core. As host drivers are converted to dev_pm_ops they'll have to construct pm_message_t's (as they won't be passed by the PM subsystem any more) just to appease the mmc suspend interface. We might as well just delete the unused paramter.

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo1-0/+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.

Raise the DMA block size limit from 2048 bytes to the maximum supported by the DMA controllers on the chip (64KB on Au1100, 4MB on Au1200).

Remove the DB1200 board-specific functions (card present, read-only, activity LED methods) and instead add platform data which is passed to the driver. This also allows for platforms to implement other carddetect schemes (e.g. dedicated irq) without having to pollute the driver code. The poll timer (used for pb1200) is kept for compatibility. With the board-specific stuff gone, the driver's ->probe() code can be cleaned up considerably.
