2010-04-13ALSA: aaci - Fix alignment faults on ARM Cortex introduced by commit 29a4f2d3Philby John
The commit 29a4f2d3 used writel() at offset 0x26 which is half-word aligned causing unaligned exceptions on a Cortex-A8. The original patch solved the "aaci-pl041 fpga:04: ac97 read back fail" issue on a soft reset. Reading from any arbitrary aaci register seems to solve this issue.

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

2009-12-26ALSA: sound/arm: Fix build failure caused by missing struct aaci definitionPeter Huewe
This patch fixes a build failure introduced by the patch ALSA: AACI: factor common hw_params logic into aaci_pcm_hw_params [1] by adding/moving the aaci struct to the right position. The patch mentioned above merged common source parts into one function, but unfortunately left out the aaci struct and consequently caused a build failure e.g. for arm versatile_config [2] References: [1] http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=d3aee7996c30f928bbbbfd0994148e35d2e83084 [2] http://kisskb.ellerman.id.au/kisskb/buildresult/1893605/ Patch against Linus' tree.

2009-10-13ALSA: aaci: ARM1176 aaci-pl041 AC97 register read timeoutPhilby John
After a reboot on an ARM1176 which amounts to a softreset, it has been noted that the ALSA driver does not get registered and the probe fails with the error "aaci-pl041 fpga:04: ac97 read back fail". In the process of reading from a register the SL1TxBusy bit is set indicating that the transceiver is busy and remains so until the default timeout occurs. Set the Power down register 0x26 to an arbitrary value as specified in the PL041 manual (page: 3-18) so that AACISL1TX/AACISL2TX registers take their default state.

2009-06-11[ARM] 5544/1: Trust PrimeCell resource sizesLinus Walleij
I found the PrimeCell/AMBA Bus drivers distrusting the resource passed in as part of the struct amba_device abstraction. This patch removes all hard coded resource sizes found in the PrimeCell drivers and move the responsibility of this definition back to the platform/board device definition, which already exist and appear to be correct for all in-tree users of these drivers. We do this using the resource_size() inline function which was also replicated in the only driver using the resource size, so that has been changed too. The KMI_SIZE was left in kmi.h in case someone likes it. Test-compiled against Versatile and Integrator defconfigs, seems to work but I don't posess these boards and cannot test them.

2009-04-15[ARM] pxa: merge AC97 platform data structuresMark Brown
Currently there are two possible platform datas for the PXA AC97 driver: one supported by the generic AC97 driver only which provides callbacks to allow board-specific configuration at stream startup and teardown, and another for pxa2xx-ac97-lib which allows configuration of the reset GPIO for PXA2xx CPUs. Obviously this won't actually work when using the generic AC97 driver since the drivers will attempt to parse the platform data in both formats. Fix this by merging the two structures.
