ASoC: sprd: Drop superfluous ioctl PCM ops

2019-12-11T15:59:40+00:00

ASoC PCM core deals the empty ioctl field now as default. Let's kill the redundant lines. Cc: Orson Zhai Cc: Baolin Wang Cc: Chunyan Zhang Signed-off-by: Takashi Iwai Reviewed-by: Baolin Wang Link: https://lore.kernel.org/r/20191210145406.21419-18-tiwai@suse.de Signed-off-by: Mark Brown

snd_pcm_ops is no longer needed. Let's use component driver callback. Signed-off-by: Kuninori Morimoto Link: https://lore.kernel.org/r/874l0raf0c.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown

ASoC: Remove dev_err() usage after platform_get_irq()

2019-08-02T11:12:31+00:00

We don't need dev_err() messages when platform_get_irq() fails now that platform_get_irq() prints an error message itself when something goes wrong. Let's remove these prints with a simple semantic patch. // @@ expression ret; struct platform_device *E; @@ ret = ( platform_get_irq(E, ...) | platform_get_irq_byname(E, ...) ); if ( \( ret < 0 \| ret <= 0 \) ) { ( -if (ret != -EPROBE_DEFER) -{ ... -dev_err(...); -... } | ... -dev_err(...); ) ... } // While we're here, remove braces on if statements that only have one statement (manually).

ASoC: sprd: Add reserved DMA memory support

2019-05-06T13:48:03+00:00

For Spreadtrum audio platform driver, it need allocate a larger DMA buffer dynamically to copy audio data between userspace and kernel space, but that will increase the risk of memory allocation failure especially the system is under heavy load situation. To make sure the audio can work in this scenario, we usually reserve one region of memory to be used as a shared pool of DMA buffers for the platform component. So add of_reserved_mem_device_init_by_idx() function to initialize the shared pool of DMA buffers to be used by the platform component. Signed-off-by: Baolin Wang Signed-off-by: Mark Brown

ASoC: sprd: Fix to use list_for_each_entry_safe() when delete items

2019-05-02T02:01:53+00:00

Since we will remove items off the list using list_del() we need to use a safe version of the list_for_each_entry() macro aptly named list_for_each_entry_safe().

ASoC: sprd: Fix return value check in sprd_mcdt_probe()

2019-05-02T02:01:17+00:00

In case of error, the function devm_ioremap_resource() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().

ASoC: sprd: Add Spreadtrum multi-channel data transfer support

2019-04-25T18:43:49+00:00

On Spreadtrum platform, the audio subsystem will use the multi-channel data transfer controller to transfer sound stream between audio subsystem and other AP/CP subsystem. It can support 10 DAC channel and 10 ADC channel, and each channel has 512 bytes depth data fifo. Moreover each channel can be used DMA mode or interrupt mode to transfer data.
