ASoC: tegra: Unify ASoC machine drivers

2021-06-15T10:43:10+00:00

Squash all machine drivers into a single-universal one. This reduces code duplication, eases addition of a new drivers and upgrades older code to a modern Linux kernel APIs.

ASoC: tegra: Set driver_name=tegra for all machine drivers

2021-06-15T10:43:09+00:00

The driver_name="tegra" is now required by the newer ALSA UCMs, otherwise Tegra UCMs don't match by the path/name. All Tegra machine drivers are specifying the card's name, but it has no effect if model name is specified in the device-tree since it overrides the card's name. We need to set the driver_name to "tegra" in order to get a usable lookup path for the updated ALSA UCMs. The new UCM lookup path has a form of driver_name/card_name. The old lookup paths that are based on driver module name continue to work as before. Note that UCM matching never worked for Tegra ASoC drivers if they were compiled as built-in, this is fixed by supporting the new naming scheme.

ASoC: tegra: Don't warn on probe deferral

2020-11-11T12:35:10+00:00

Deferred probe is an expected return value for snd_soc_register_card(). Given that the driver deals with it properly, there's no need to output a warning that may potentially confuse users.

ASoC: tegra: Use device managed resource APIs to get the clock

2020-04-21T14:53:12+00:00

tegra_asoc_utils uses clk_get() to get the clock and clk_put() to free them explicitly. This patch updates it to use device managed resource API devm_clk_get() so the clock will be automatically released and freed when the device is unbound and removes tegra_asoc_utils_fini() as its no longer needed.

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.

ALSA SoC is now supporting "no Platform". Sound card doesn't need to select "CPU component" as "Platform" anymore if it doesn't need special Platform. This patch removes such settings. Signed-off-by: Kuninori Morimoto Signed-off-by: Mark Brown
