Currently the SDHI glue for the TMIO MMC driver installs dummy .get_cd() and .set_pwr() callbacks even if the platform didn't supply them. This is not necessary, since the TMIO MMC driver itself checks for NULL callbacks. This is also dubious if the platform provides a regulator for SD-card power switching. It is better to only install those callbacks, if they are really provided by the platform. Signed-off-by: NGuennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: NChris Ball <cjb@laptop.org>

Currently if a platform wants to implement a non-standard card-detection method, it would need to call tmio_mmc_cd_wakeup(), which is an inline function, calling mmc_detect_change(). For this the platform would have to link mmc_core statically into the kernel, losing the ability to build it as a module. This patch adds a callback to the sh_mobile_sdhi driver, which eliminates this dependency.

On sh-mobile platforms the MMC clock frequency for the TMIO MMC unit is obtained from the same clock, as the one, that runtime power-manages the controller. The SDHI glue code has to access that clock directly, bypassing the runtime PM framework, to get its frequency, but it shouldn't enable or disable it.

Allow named IRQs to use corresponding specific handlers. If named IRQs are used, at least an "sdcard" IRQ has to be specified by the platform. If names are not used, an arbitrary number of IRQs can be provided by the platform, in which case the generic ISR will be used for each of them.

Some controllers require waiting for the bus to become idle before writing to some registers. I have implemented this by adding a hook to sd_ctrl_write16() and implementing a hook for SDHI which waits for the bus to become idle.

On sh-mobile platforms the SDHI driver was using the tmio_mmc SD/SDIO MFD cell driver. Now that the tmio_mmc driver has been split into a core and a separate MFD glue, we can support SDHI natively without the need to emulate an MFD controller. This also allows to support systems with an on-SoC SDHI controller and a separate MFD with a TMIO core.

include cleanup: Update gfp.h and slab.h includes to prepare for breaking 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.
