From b9a1a743818ea3265abf98f9431623afa8c50c86 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 18 Nov 2015 15:25:23 +0100 Subject: ASoC: samsung: pass DMA channels as pointers 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.

I'm keeping this change separate, as there it's less obvious that this is a net win. Upsides of this are: - The ASoC drivers are completely independent from the DMA engine implementation, which simplifies the Kconfig logic and in theory allows the same sound drivers to be built in a kernel that supports different kinds of dmaengine drivers. - Consistency with other subsystems and drivers On the other hand, we have a few downsides: - The s3c24xx-dma driver now needs to be built-in for the ac97 platform device to be instantiated on s3c2440. - samsung_dmaengine_pcm_config cannot be marked 'const' any more because the filter function pointer needs to be set at runtime. This is safe as long we don't have multiple different DMA engines in thet same system at runtime, but is nonetheless ugly.

This changes the common device creation functions for s3c64xx (but not s3c24xx for now) to use the new driver. To do this, we have to pass the interrupt resources in the opposite order and pass the platform data in the adc device node.
