2009-10-20omap: headers: Move remaining headers from include/mach to include/platTony Lindgren
Move the remaining headers under plat-omap/include/mach to plat-omap/include/plat. Also search and replace the files using these headers to include using the right path.

2009-08-28ASoC: OMAP: Add functionality to set CLKR and FSR sources in McBSP DAIJarkko Nikula
The McBSP1 port in OMAP3 processors (I believe OMAP2 too but I don't have specifications to check it) have additional CLKR and FSR pins for McBSP1 receiver. Reset default is that receiver is using bit clock and frame sync signal from those pins but it is possible to configure to use also CLKX and FSX pins as well. In fact, other McBSP ports are doing that internally that transmitter and receiver share the CLKX and FSX. Add functionaly that machine drivers can set the CLKR and FSR sources by using the snd_soc_dai_set_sysclk. Thanks to "Aggarwal, Anuj" <anuj.aggarwal@ti.com> for reporting the issue.

2009-08-25ARM: OMAP: McBSP: Merge two functions into omap_mcbsp_start/_stopJarkko Nikula
Functionality of functions omap_mcbsp_xmit_enable and omap_mcbsp_recv_enable can be merged into omap_mcbsp_start and omap_mcbsp_stop since API of those omap_mcbsp_start and omap_mcbsp_stop was changed recently allowing to start and stop individually the transmitter and receiver. This cleans up the code in arch/arm/plat-omap/mcbsp.c and in sound/soc/omap/omap-mcbsp.c which was the only user for those removed functions.

2009-08-25ASoC: OMAP: Fix setup of XCCR and RCCR registers in McBSP DAIJarkko Nikula
Commit ca6e2ce08679c094878d7f39a0349a7db1d13675 is setting up few XCCR and RCCR bits for I2S and DPS_A formats. Part of the bits are already set for all formats and I believe that XDISABLE and RDISABLE bits are format independent. As XCCR and RCCR are found only from OMAP2430 and OMAP34xx, I move setup of XDISABLE and RDISABLE to where those cpu's are tested and remove format dependent part for simplicity.

2009-08-20ASoC: OMAP: Use DMA operating mode of McBSPEduardo Valentin
Configures DMA sync mode depending on McBSP operating mode value. The value is configurable by McBSP instance. So, depending on McBSP operating mode, the DMA sync mode is passed from omap-mcbsp to omap-pcm. Besides that, it also configures McBSP threshold value depending on which McBSP mode is activated.

2009-08-20ASoC: OMAP: Use McBSP threshold to playback and captureEduardo Valentin
This patch changes the way DMA is done in omap-pcm.c in order to reduce power consumption. There is no need to have so much SW control in order to have DMA in idle state during audio streaming. Configuring McBSP threshold value and DMA to FRAME_SYNC are sufficient.

2009-08-20ASoC: Always syncronize audio transfers on framesEero Nurkkala
All these steps are required for ASoC to behave correctly. rccr and xccr are format dependent, for example TDM audio has different values than I2S or DSP_A. Also the omap_mcbsp_xmit_enable and/or omap_mcbsp_recv_enable must be called right after the DMA has started. This provides no longer L and R channels switching at random.

2009-08-07ARM: OMAP: McBSP: Fix ASoC on OMAP1510 by fixing API of omap_mcbsp_start/stopJarkko Nikula
Simultaneous audio playback and capture on OMAP1510 can cause that second stream is stalled if there is enough delay between startup of the audio streams. Current implementation of the omap_mcbsp_start is starting both transmitter and receiver at the same time and it is called only for firstly started audio stream from the OMAP McBSP based ASoC DAI driver. Since DMA request lines on OMAP1510 are edge sensitive, the DMA request is missed if there is no DMA transfer set up at that time when the first word after McBSP startup is transmitted. The problem hasn't noted before since later OMAPs are using level sensitive DMA request lines. Fix the problem by changing API of omap_mcbsp_start and omap_mcbsp_stop by allowing to start and stop individually McBSP transmitter and receiver logics. Then call those functions individually for both audio playback and capture streams. This ensures that DMA transfer is setup before transmitter or receiver is started. Thanks to Janusz Krzysztofik <jkrzyszt@tis.icnet.pl> for detailed problem analysis and Peter Ujfalusi <peter.ujfalusi@nokia.com> for info about DMA request line behavior differences between the OMAP generations.

2009-04-02ASoC: OMAP: Set minimum buffer size constraint for McBSP2 in OMAP3Jarkko Nikula
McBSP2 in OMAP3 has 1 ksample (1k x 32 bit) internal FIFO. During initial playback startup, this FIFO is keeping the DMA request active until the FIFO is full. So now if ALSA buffer size is smaller, DMA is looping around it while filling up the HW FIFO, generating burst of interrupts as well and SW doesn't have any change to fill enough data.

2009-03-04ASoC: make ops a pointer in 'struct snd_soc_dai'Eric Miao
Considering the fact that most cpu_dai or codec_dai are using a same 'snd_soc_dai_ops' for several similar interfaces, 'ops' would be better made a pointer instead, to make sharing easier and code a bit cleaner. The patch below is rather preliminary since the asoc tree is being actively developed, and this touches almost every piece of code, (and possibly many others in development need to be changed as well). Building of all codecs are OK, yet to every SoC, I didn't test that.

2009-01-29ASoC: OMAP: Initialize XCCR and RCCR registers in McBSP DAI driverMisael Lopez Cruz

Reset values are 26 ns of DX delay and Transmit DMA disabled for XCCR register; receive full cycle mode enabled and Receive DMA disabled for RCCR register. This patch requires a counterpart in OMAP McBSP driver before to apply it.

Register all platform DAIs with the core.
