ASoC: sprd: Allow the MCDT driver to build into modules
Change the config to 'tristate' for MCDT driver to allow it to build into
modules, as well as changing to use IS_ENABLED() to validate if need supply
dummy functions when building the MCDT driver as a module.

ASoC: sprd: Drop superfluous ioctl PCM ops
ASoC PCM core deals the empty ioctl field now as default.
Let's kill the redundant lines.

ASoC: Remove dev_err() usage after platform_get_irq()
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).

ASoC: sprd: Add reserved DMA memory support
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.

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

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

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

ASoC: sprd: Add Spreadtrum audio compress offload support
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.
