ASoC: tegra: Revert 24 and 32 bit support

2020-02-02T12:07:47+00:00

Commit f3ee99087c8ca0ecfdd549ef5a94f557c42d5428 ("ASoC: tegra: Allow 24bit and 32bit samples") added 24-bit and 32-bit support for to the Tegra30 I2S driver. However, there are two additional commits that are also needed to get 24-bit and 32-bit support to work correctly. These commits are not yet applied because there are still some review comments that need to be addressed. With only this change applied, 24-bit and 32-bit support is advertised by the I2S driver, but it does not work and the audio is distorted. Therefore, revert this patch for now until the other changes are also ready. Furthermore, a clock issue with 24-bit support has been identified with this change and so if we revert this now, we can also fix that in the updated version.

ASoC: soc-core: remove bus_control

2020-01-21T17:07:08+00:00

Now, snd_soc_dai_driver::bus_control is used for how to resume. But, no driver which has bus_control has DAI driver suspend/resume support. This patch removes pointless bus_control from ALSA SoC.

ASoC: soc-core: find rtd via dai_link pointer at snd_soc_get_pcm_runtime()

2019-12-10T13:15:21+00:00

Current snd_soc_get_pcm_runtime() is finding rtd by checking dai_link name. But, it is strange and waste of CPU power, because its user want to get from rtd from dai_link, not from dai_link name. This patch find rtd via dai_link pointer instead of its name.

ASoC: tegra: disable rx_fifo after disable stream

2019-10-25T10:07:33+00:00

We see odd FIFO overruns with this, we assume the best thing to do is to disable the RX I2S frontend first, and then disable the FIFO that is using it. This also fixes an issue where using multi-word frames (TDM) have partial samples stuck in the FIFO which then get read out when the next capture is started.

ASoC: tegra: trimslice: consider CPU-Platform possibility

2019-06-28T14:18:45+00:00

commit 567b374d9973 ("ASoC: tegra: trimslice: don't select unnecessary Platform") Current ALSA SoC avoid to add duplicate component to rtd, and this driver was selecting CPU component as Platform component. Thus, above patch removed Platform settings from this driver, because it assumed these are same component. But, some CPU driver is using generic DMAEngine, in such case, both CPU component and Platform component will have same of_node/name. In other words, there are some components which are different but have same of_node/name. In such case, Card driver definitely need to select Platform even though it is same as CPU. It is depends on CPU driver, but is difficult to know it from Card driver. This patch reverts above patch.
