2019-06-28ASoC: atmel: atmel-classd: consider CPU-Platform possibilityKuninori Morimoto1-1/+4
commit 02602401e5316 ("ASoC: atmel: atmel-classd: 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.

2019-06-19ASoC: atmel: atmel-classd: don't select unnecessary PlatformKuninori Morimoto1-4/+1
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 <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2017-12-04ASoC: use snd_soc_component_init_regmap() on atmel-classdKuninori Morimoto1-6/+0
To setup regmap, ALSA SoC has snd_soc_component_init_regmap() and .get_regmap. But these are duplicated feature. This driver is using .get_regmap and set regmap by using dev_get_regmap(), but it is automatically done by snd_soc_component_add_unlocked(). let's remove .get_regmap.

2017-09-02ASoC: atmel-classd: remove aclk clockQuentin Schulz1-33/+14
Since gclk (generated-clk) is now able to determine the rate of the audio_pll, there is no need for classd to have a direct phandle to the audio_pll while already having a phandle to gclk. Thus, remove all mentions to aclk in classd driver and update macros and variable names.

2017-08-21ASoC: atmel: Remove unnecessary function callDonglin Peng1-1/+0
The function platform_set_drvdata copies the value the variable card to card->dev->driver_data, then the address of &pdev->dev is assigned to card->dev in atmel_classd_asoc_card_init, but when calling snd_soc_register_card,the function dev_set_drvdata(card->dev, card) will do the same copy operation, so i think that the former copy operation can be removed.
