dmaengine: remove Renesas Audio DMAC peri peri

2015-03-18T08:27:54Z

Renesas R-Car sound (= rsnd) needs 2 DMAC which are called as Audio DMAC (= 1st DMAC) and Audio DMAC peri peri (2nd DMAC). And rsnd had assumed that 1st / 2nd DMACs are implemented as DMAEngine. But, in result of DMA ML discussion, 2nd DMAC was concluded that it is not a general purpose DMAC (2nd DMAC is for Device to Device inside sound system). Additionally, current DMAEngine can't support Device to Device, and we don't have correct DT bindings for it at this point. So the easiest solution for it is that move it from DMAEngine to rsnd driver. Audio DMAC peri peri on DMAEngine is no longer needed. remove it.

dmaengine: Remove .owner field for driver

2014-11-06T06:24:18Z

There is no need to init .owner field. Based on the patch from Peter Griffin "mmc: remove .owner field for drivers using module_platform_driver" This patch removes the superflous .owner field for drivers which use the module_platform_driver API, as this is overriden in platform_driver_register anyway."

dmaengine: sh: Remove chancnt affectations

2014-11-06T06:03:07Z

chanctnt is already filled by dma_async_device_register, which uses the channel list to know how much channels there is. Since it's already filled, we can safely remove it from the drivers' probe function. Signed-off-by: Maxime Ripard Acked-by: Laurent Pinchart Signed-off-by: Vinod Koul

dma: rcar-audmapp: Fix for no corresponding slave ID

2014-08-28T07:12:10Z

In case of no corresponding slave ID, the audmapp_set_slave() returns -ENXIO same as sh_dmae_set_slave() of shdmac.c. DMAEngine might return wrong channel without this patch Signed-off-by: Ryo Kataoka Signed-off-by: Jun Watanabe , Signed-off-by: Kuninori Morimoto Signed-off-by: Vinod Koul

dma: rcar-audmapp: add DT support

This patch adds DT support to Audio DMAC peri peri driver.

dma: rcar-audmapp: don't keep audmapp_slave_config for each channeles

2014-07-08T09:12:28Z

Current audmapp driver is keeping audmapp_slave_config for each channeles, but, nessasary information is only "chcr". Current style (= keeping audmapp_slave_config) is not good match for DT support. Keep "chcr" instead of audmapp_slave_config Signed-off-by: Kuninori Morimoto Signed-off-by: Simon Horman

dma: rcar-audmapp: enable .set_slave

2014-07-08T09:07:11Z

Current .set_slave callback did nothing, since it assumed src/dst address come from platform settings. But, it isn't good match to DT probing. This patch enables .set_slave callback to this issue. Signed-off-by: Kuninori Morimoto Signed-off-by: Simon Horman
