2009-11-18ASoC: Rename 's3c24xx-pcm' driver to 's3c-dma'Jassi Brar1-480/+0
Making room for namespace for the PCM Controller driver the platform driver(s3c24xx-pcm) has been renamed to SoC agnostic name 's3c-dma'.

2009-11-18ASoC: Rename s3c24xx_pcm prefix to s3c_dmaJassi Brar1-38/+38
The s3c24xx_pcm prefix for the soc_platform is inappropriate when some Samsung SoCs have PCM controllers which will eventually have drivers and hence namespace ambiguities. To resolve naming ambiguities in future the following have been renamed in order 1) s3c24xx_pcm_dma_params -> s3c_dma_params 2) s3c24xx_pcm_preallocate_dma_buffer -> s3c_preallocate_dma_buffer 3) s3c24xx_pcm_dmamask -> s3c_dma_mask 4) s3c24xx_pcm_XXX -> s3c_dma_XXX Signed-off-by: Jassi Brar <jassi.brar@samsung.com> Acked-by: Ben Dooks <ben-linux@fluff.org> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2009-10-28ARM: S3C: Add info for supporting circular DMA buffersBen Dooks1-2/+15
The S3C64XX DMA implementation will work a lot better with the ability to enqueue circular buffers as the hardware can do it's own linked-list management. Add a function s3c_dma_has_circular() to show that the system can do this and a flag for the channel. Update the s3c24xx/s3c64xx I2S DMA code to deal with this.

2009-08-25ASoC: S3C platform: Fix s3c2410_dma_started() called at improper timeShine Liu1-1/+0
s3c24xx dma has the auto reload feature, when the the trnasfer is done, CURR_TC(DSTAT[19:0], current value of transfer count) reaches 0, and DMA ACK becomes 1, and then, TC(DCON[19:0]) will be loaded into CURR_TC. So the transmission is repeated. IRQ is issued while auto reload occurs. We change the DISRC and DCON[19:0] in the ISR, but at this time, the auto reload has been performed already. The first block is being re-transmitted by the DMA. So we need rewrite the DISRC and DCON[19:0] for the next block immediatly after the this block has been started to be transported. The function s3c2410_dma_started() is for this perpose, which is called in the form of "s3c2410_dma_ctrl(prtd->params->channel, S3C2410_DMAOP_STARTED);" in s3c24xx_pcm_trigger(). But it is not correct. DMA transmission won't start until DMA REQ signal arrived, it is the time s3c24xx_snd_txctrl(1) or s3c24xx_snd_rxctrl(1) is called in s3c24xx_i2s_trigger(). In the current framework, s3c24xx_pcm_trigger() is always called before s3c24xx_pcm_trigger(). So the s3c2410_dma_started() should be called in s3c24xx_pcm_trigger() after s3c24xx_snd_txctrl(1) or s3c24xx_snd_rxctrl(1) is called in this function. However, s3c2410_dma_started() is dma related, to call this function we should provide the channel number, which is given by substream->runtime->private_data->params->channel. The private_data points to a struct s3c24xx_runtime_data object, which is define in s3c24xx_pcm.c, so s3c2410_dma_started() can't be called in s3c24xx_i2s.c Fix this by moving the call to signal the DMA started to the DAI drivers.

2009-08-20ASoC: S3C24XX : Align the peroid size to the buffer sizeShine Liu1-0/+1
> Then it's a driver bug. If unaligned period size is allowed, it means > that the irq is really generated in that period, not at the buffer > boundary. Otherwise, it must have a proper hw-constraint to align the > period size to the buffer size. This patch will fix the bug metioned in the above mail. Force the peroid size to be aligned with the buffer size. Based and tested on linux-2.6.31-rc6.

2009-05-01[ARM] S3C24XX: Remove hardware specific registers from DMABen Dooks1-14/+7
calls The S3C24XX DMA API channel configuration registers are being passed values comprised of register values which makes it hard to move the API to cover both the S3C24XX and S3C64XX. These values can be calculated from knowing which device the channel is connected to, so remove them from the two calls s3c2410_dma_config and s3c2410_dma_devconfig.

2008-11-14ASoC: Revert "ASoC: Add new parameter to s3c24xx_pcm_enqueue"Mark Brown1-8/+4
This reverts commit 8dc840f88d9c9f75f46d5dbe489242f8a114fab6. Christian Pellegrin <chripell@gmail.com> reported that on some systems the patch caused DMA to fail which is much more serious than the original skipped audio issue. Further investigation by Dave shows that the behaviour depends on the clock speed of the SoC - a better fix is neeeded. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
