2011-04-03ASoC: PXA: Fix oops in __pxa2xx_pcm_prepareVasily Khoruzhick
pxa2xx_pcm_hw_free frees dma channel and sets prtd->dma_ch to -1, but does not set prtd->params to NULL, so if pxa2xx_pcm_hw_params will be called immediately, it leaves prtd->dma_ch initialized with -1, and it results in oops in __pxa2xx_pcm_prepare. This bug is triggered via SDL. This patch adds check for prtd->dma_ch to __pxa2xx_pcm_prepare and cleans prtd->params, so now it works properly.

Make Primecell driver probe functions take a const pointer to their ID tables. Drivers should never modify their ID tables in their probe handler. Signed-off-by: Russell King <>
2011-02-07ALSA: AACI: allow writes to MAINCR to take effectRussell King
The AACI TRM requires the MAINCR enable bit to be held zero for two bitclk cycles plus three apb_pclk cycles. Use a delay of 1us to ensure this. Ensure that writes to MAINCR to change the addressed codec only happen when required, and that they take effect in a similar manner to the above, otherwise we seem to occasionally have stuck slot busy bits.

2011-01-26ALSA: AACI: no need to call snd_pcm_period_elapsed() for each periodRussell King
There is no need to call snd_pcm_period_elapsed() each time a period elapses - we can call it after we're done once loading/unloading the FIFO with data. ALSA works out how many periods have elapsed by reading the current pointers. Signed-off-by: Russell King <>

2011-01-26ALSA: AACI: fix channel mask selectionRussell King
When double-rate mode was selected, we weren't setting the additional two channel mask bits to allow double-rate to work. Rearrange the hw_params code to allow the correct channel mask to be selected. Signed-off-by: Russell King <>
2011-01-25ALSA: AACI: fix number of channels for recordRussell King
AC'97 codecs only support two channels for recording, so we shouldn't advertize that there are up to six channels available. Limit the selection of 4 and 6 channel audio to playback only. As this adds additional SNDRV_PCM_STREAM_PLAYBACK conditionals, we can combine some resulting in the elimination of __aaci_pcm_open() entirely, and making the code easier to read. Signed-off-by: Russell King <>
2011-01-25ALSA: AACI: fix multiple IRQ claimingRussell King
Claiming the IRQ each time a playback or capture interface is opened is wasteful; the second copy of the registered handler is identical to the first and just wastes resources. Track the number of opens and only register the handler when necessary. Signed-off-by: Russell King <>
2011-01-25ALSA: AACI: fix timeout durationRussell King
Relying on the access time of peripherals is unreliable - it depends on the speed of the CPU and the bus. On Versatile Express, these timeouts were expiring, causing the driver to fail. Add udelay(1) to ensure that they don't expire early, and adjust timeouts to give a reasonable margin over the response times. Signed-off-by: Russell King <>
2011-01-25ALSA: AACI: fix timeout condition checkingRussell King
Ensure that a timeout coincident with the condition being waited for results in success rather than failure. This helps avoid timeout conditions being inappropriately flagged. Signed-off-by: Russell King <>

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. 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.

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];a=commitdiff;h=d3aee7996c30f928bbbbfd0994148e35d2e83084 [2] 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.
