2015-11-21ASoC: sh: fix fsi build warnings for 64 bitArnd Bergmann1-4/+7
As this driver can now be compiled for ARM64, we get a new warning as a result of passing a DMA filter data pointer through an 'int': sound/soc/sh/fsi.c: In function 'fsi_dma_probe': sound/soc/sh/fsi.c:1372:24: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] shdma_chan_filter, (void *)io->dma_id, We already know that we only need the legacy filter function on arch/sh, so we can hide the legacy DMA interface function behind an #ifdef. This has the other advantage of no longer depending on the shdma_chan_filter function to be visible. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-07-16ASoC: fsi: Remove obsolete sh_fsi2 platform_device_id entryGeert Uytterhoeven1-1/+0
Since the removal of the r8a7740 legacy board code in commit 1fa59bda21c7fa36 ("ARM: shmobile: Remove legacy board code for Armadillo-800 EVA"), all former users of the "sh_fsi2" platform device name are only supported in generic DT-only ARM multi-platform builds. The driver doesn't need to match platform devices by name anymore, hence remove the corresponding platform_device_id entry.

2014-08-17ASoC: sh: Fix dma direction typeLars-Peter Clausen1-1/+6
dmaengine_prep_slave_single() expects a enum dma_transfer_direction and not a enum dma_data_direction. Since the integer representations of both DMA_TO_DEVICE and DMA_MEM_TO_DEV aswell as DMA_FROM_DEVICE and DMA_DEV_TO_MEM have the same value the code worked fine even though it was using the wrong type.

2014-06-28ASoC: fsi: use dmaengine_prep_dma_cyclic() for DMA transferKuninori Morimoto1-67/+27
Current FSI driver is using DMAEngine directly, but, ASoC is requesting to use common DMA transfer method, like snd_dmaengine_pcm_trigger() or dmaengine_pcm_ops. It is difficult to switch at this point, since Renesas driver is also supporting PIO transfer. This patch uses dmaengine_prep_dma_cyclic() instead of dmaengine_prep_slave_single(). It is used in requested method, and is good first step to switch over. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@linaro.org>

2014-06-21ASoC: sh/fsi: Make one-bit bitfields unsignedLars-Peter Clausen1-6/+6
One-bit signed bitfields have two possible values: 0 and -1. This sometimes leads to unexpected results (e.g. foo.bar = 1; foo.bar == 1 => false) which is why it is recommended to make one-bit bitfields unsigned.

2014-01-09ASoC: sh: Don't set unused struct snd_pcm_hardware fieldsLars-Peter Clausen1-6/+0
The ASoC core assumes that the PCM component of the ASoC card transparently moves data around and does not impose any restrictions on the memory layout or the transfer speed. It ignores all fields from the snd_pcm_hardware struct for the PCM driver that are related to this. Setting these fields in the PCM driver might suggest otherwise though, so rather not set them.
