* crypto: marvell/cesa - another fix up for of_get_named_gen_pool() renameStephen Rothwell2015-07-031-2/+2

* crypto: mv_cesa - explicitly define kirkwood and dove compatible stringsBoris BREZILLON2015-06-191-1/+3
| | | | | | | | | | | | | | | | | We are about to add a new driver to support new features like using the TDMA engine to offload the CPU. Orion, Dove and Kirkwood platforms are already using the mv_cesa driver, but Orion SoCs do not embed the TDMA engine, which means we will have to differentiate them if we want to get TDMA support on Dove and Kirkwood. In the other hand, the migration from the old driver to the new one is not something all people are willing to do without first auditing the new driver. Hence we have to support the new compatible in the mv_cesa driver so that new platforms with updated DTs can still attach their crypto engine device to this driver.

* crypto: mv_cesa - use gen_pool to reserve the SRAM memory regionBoris BREZILLON2015-06-191-15/+43
| | | | | | | | | | | | | | | | | | | | | | | The mv_cesa driver currently expects the SRAM memory region to be passed as a platform device resource. This approach implies two drawbacks: - the DT representation is wrong - the only one that can access the SRAM is the crypto engine The last point is particularly annoying in some cases: for example on armada 370, a small region of the crypto SRAM is used to implement the cpuidle, which means you would not be able to enable both cpuidle and the CESA driver. To address that problem, we explicitly define the SRAM device in the DT and then reference the sram node from the crypto engine node. Also note that the old way of retrieving the SRAM memory region is still supported, or in other words, backward compatibility is preserved.

* crypto: mv_cesa - request registers memory regionBoris BREZILLON2015-05-251-8/+5Star
| | | | | | | | | | The mv_cesa driver does not request the CESA registers memory region. Since we're about to add a new CESA driver, we need to make sure only one of these drivers probe the CESA device, and requesting the registers memory region is a good way to achieve that.

| * 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.
