2020-12-28ASoC: sprd: Switch to use list_entry_is_head() helperAndy Shevchenko1-5/+5
Since we got list_entry_is_head() helper in the generic header, we may switch driver to use it. This eliminates the need in additional variable.

2019-08-02ASoC: Remove dev_err() usage after platform_get_irq()Stephen Boyd1-3/+1
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. // <smpl> @@ 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(...); ) ... } // </smpl> While we're here, remove braces on if statements that only have one statement (manually).

2019-05-06ASoC: sprd: Add reserved DMA memory supportBaolin Wang1-0/+7
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.

2019-04-25ASoC: sprd: Add Spreadtrum multi-channel data transfer supportBaolin Wang4-0/+1128
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.

2019-04-02ASoC: sprd: Add Spreadtrum audio compress offload supportBaolin Wang5-2/+721
We use 2-stage DMA mode to support Spreadtrum audio compress offload, which means we use one DMA source channel to transfer data from IRAM buffer to the DSP fifo to do decoding/encoding, once IRAM buffer is empty by transferring done, another DMA destination channel will be triggered automatically to start to transfer data from DDR buffer to the IRAM buffer. This can reduce the AP subsystem wakeup times to save power.
