kernel/sound/soc/sprd/Kconfig, branch linux-6.2.yHosts the 0x221E linux distro kernel.https://universe.0xinfinity.dev/distro/kernel/atom?h=linux-6.2.y2020-03-05T13:15:17ZASoC: sprd: Allow the MCDT driver to build into modules2020-03-05T13:15:17ZBaolin Wangbaolin.wang7@gmail.com2020-03-05T06:00:53Zurn:sha1:fd357ec595d36676c239d8d16706a270a961ac32
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: Add Spreadtrum multi-channel data transfer support2019-04-25T18:43:49ZBaolin Wangbaolin.wang@linaro.org2019-04-23T02:26:22Zurn:sha1:d7bff893e04f4e7b4a0789486da1435df5920f5a
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 support2019-04-02T05:57:03ZBaolin Wangbaolin.wang@linaro.org2019-03-27T11:47:03Zurn:sha1:cce1396936ef2b347d622b4d49718818eb32029d
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.

The Spreadtrum DMA engine uses the link-list mode to support audio playback
or capture, thus this patch adds audio DMA platform support for CPU DAI to
trigger DMA link-list transfer.
