ASoC: samsung: pass DMA channels as pointers

2016-04-12T16:08:32+00:00

commit b9a1a743818ea3265abf98f9431623afa8c50c86 upstream. ARM64 allmodconfig produces a bunch of warnings when building the samsung ASoC code: sound/soc/samsung/dmaengine.c: In function 'samsung_asoc_init_dma_data': sound/soc/samsung/dmaengine.c:53:32: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] playback_data->filter_data = (void *)playback->channel; sound/soc/samsung/dmaengine.c:60:31: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] capture_data->filter_data = (void *)capture->channel; We could easily shut up the warning by adding an intermediate cast, but there is a bigger underlying problem: The use of IORESOURCE_DMA to pass data from platform code to device drivers is dubious to start with, as what we really want is a pointer that can be passed into a filter function. Note that on s3c64xx, the pl08x DMA data is already a pointer, but gets cast to resource_size_t so we can pass it as a resource, and it then gets converted back to a pointer. In contrast, the data we pass for s3c24xx is an index into a device specific table, and we artificially convert that into a pointer for the filter function.

ASoC: Samsung: I2S: Modify the I2S driver to support I2S on Exynos5420

2013-08-13T12:44:09+00:00

Exynos5420 added support for I2S TDM mode. For this, there are some register changes in the I2S controller. This patch adds the relevant register changes to support I2S in normal mode. This patch adds a quirk for TDM mode and if TDM mode is present all the relevent changes will be applied. Signed-off-by: Padmavathi Venna Reviewed-by: Tomasz Figa Signed-off-by: Mark Brown

ASoC: Samsung: Get I2S src_clk from clock alias id.

2012-11-28T19:18:00+00:00

As the I2S src clks are registered with clkdev using generic connection id, driver can get the clk name using generic id. So the variable representing the array of rclk src clks is deleted. Signed-off-by: Padmavathi Venna Signed-off-by: Mark Brown

ARM: samsung: move platform_data definitions

2012-09-19T15:42:18+00:00

Platform data for device drivers should be defined in include/linux/platform_data/*.h, not in the architecture and platform specific directories.
