ASoC: samsung: pass DMA channels as pointers

2016-04-12T16:08:32Z

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.

dmaengine: edma: DT: Change memcpy channel array from 16bit to 32bit type

2015-12-10T03:01:10Z

This change makes the DT file to be easier to read since the memcpy channels array does not need the '/bits/ 16' to be specified, which might confuse some people. Signed-off-by: Peter Ujfalusi Acked-by: Arnd Bergmann Acked-by: Rob Herring Acked-by: Tony Lindgren Signed-off-by: Vinod Koul

leds: netxbig: add device tree binding

2015-11-03T07:59:25Z

This patch adds device tree support for the netxbig LEDs. This also introduces a additionnal DT binding for the GPIO extension bus (netxbig-gpio-ext) used to configure the LEDs. Since this bus could also be used to control other devices, then it seems more suitable to have it in a separate DT binding.
