* ENGR00305624-1 ASoC: imx-hdmi-dma: Use neon data copy functionNicolin Chen2014-04-16
| | | | | | | | | | Use neon data copy function as default to improve data copy performance so that we can prevent some noise issue happening to HDMI audio due to the performance issue.

* ENGR00304914-1 ASoC: imx-hdmi-dma: Limit period size for 6DQNicolin Chen2014-04-16
| | | | | | | | | | | | The HDMI IP in i.MX6DQ has a bug that it limits the dma period size within 8K. Patch 'ENGR00300188-1 ASoC: imx-hdmi-dma: Double the buffer and period sizes' doubled the period size which works great with Dual Lite but broke the HDMI audio function on DQ. Thus fix it for 6DQ case. Acked-by: Wang Shengjiu <b02247@freescale.com> Signed-off-by: Nicolin Chen <Guangyu.Chen@freescale.com> (cherry picked from commit 5b5f5e3f7b1dd41022e6e587460fd912fcd481d0)
* ASoC: fsl_sai: Improve fsl_sai_isr()Nicolin Chen2014-04-16
| | | | | | | | | | | This patch improves fsl_sai_isr() in these ways: 1, Add comment for mask fetching code. 2, Return IRQ_NONE if the IRQ is not for the device. 3, Use regmap_write() instead of regmap_update_bits().

* ASoC: fsl_sai: Add isr to deal with error flagNicolin Chen2014-04-16
| | | | | | | | | | | | | It's quite cricial to clear error flags because SAI might hang if getting FIFO underrun during playback (I haven't confirmed the same issue on Rx overflow though). So this patch enables those irq and adds isr() to clear the flags so as to keep playback entirely safe.

| | | | | | | | | | The current imx-sgtl5000 driver always attaches the cpu-dai to ssi while in fact it could be attached to other cpu-dais like SAI.

* ENGR00300188-2 ASoC: imx-hdmi-dma: Clear offset in the trigger initNicolin Chen2014-04-16
| | | | | | | | | | The offset reflects the current position of DMA access in the ALSA ring buffer. So we should clear it before re-start DMA engine becasue the DMA access should re-start its job from the 0 position. If we don't do this, the driver might get a wrong idea about current position of DMA access. Thus fix it.

* ENGR00300188-1 ASoC: imx-hdmi-dma: Double the buffer and period sizesNicolin Chen2014-04-16
| | | | | | | | | | | | | | | | We found HDMI Audio has a performance issue when playback 8 channels 192KHz files, CPU might lag its interrupt responsing while SDMA continues updating HDMI internal AHB DMA's address and restarting AHB DMA, which resulted the noise when AHB DMA access overlaps with the data copy procedures in this driver. Thus we here double the buffer size and period size of HDMI Audio to chop the CPU interrupt to its half in the same span of time so that we can keep the data copy procedures safe and provent it from overlapping access with AHB DMA.
