2012-09-20ASoC: Ux500: Minor coding layout changesLee Jones1-5/+2
Includes removal of duplicate debug print affirming entry into the probe function, an unnecessary line break of a coding line <80 chars and a white space change (unintentional tab). Acked-by: Ola Lilja <ola.o.lilja@stericsson.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2012-09-20ASoC: Ux500: Enable ux500 MSP driver for Device TreeLee Jones2-3/+25
Register both parts of the MSP driver from Device Tree so that they are probed when Device Tree is enabled. Also, as there is platform data involved, we ensure that there is allocated memory to place the configuration into and that the correct information is extracted from the DT binary.

2012-09-20ASoC: Ux500: Enable MOP500 driver for Device TreeLee Jones1-0/+40
Here we ensure that the MOP500 audio driver will be probed during a Device Tree boot. We also parse the sound node to link together the codec, dma and the CPU-side Digital Audio Interface.

2012-09-20ASoC: Ux500: Move MSP pinctrl setup into the MSP driverLee Jones2-18/+57
In the initial submission of the MSP driver msp1 and msp3's associated pinctrl mechanism was passed back to platform code using a plat_init() call-back routine, but it has no place in platform code. The MSP driver should set this up for the appropriate ports. Instead we use a use_pinctrl identifier which is passed from platform_data/Device Tree which indicates which ports should use pinctrl.

2012-08-20ASoC: ux500_msp_i2s: better use devm functions and fix error return codeJulia Lawall1-20/+5
Remove unnecessary calls to devm_kfree and replace iounmap by devm_iounmap (and use resource_size for the third argument). These changes make it possible to remove the error-handling code at the end of ux500_msp_i2s_init_msp, and all of the gotos become direct returns. In the case of the second call to devm_kzalloc, the return variable ret was not initialized. Here it is changed to a direct return of -ENOMEM. A simplified version of the semantic match that finds the second problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-07-26ASoC: ux500: Include the correct header filesLee Jones3-3/+3
Thought to be another merge error, board-mop500-msp.h has never existed in the upstream kernel, only msp.h. This patch changes the include files to match the existing file name. Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-06-20ASoC: dmaengine-pcm: Rename and deprecate snd_dmaengine_pcm_pointerLars-Peter Clausen1-1/+1
Currently the sound dmaengine pcm helper functions implement the pcm_pointer callback by trying to count the number of elapsed periods. This is done by advancing the stream position in the dmaengine callback by one period. Unfortunately there is no guarantee that the callback will be called for each elapsed period. It may be possible that under high system load it is only called once for multiple elapsed periods. This patch renames the current implementation and documents its shortcomings and that it should not be used anymore in new drivers. The next patch will introduce a new snd_dmaengine_pcm_pointer which will be implemented based on querying the current stream position from the dma device.
