2022-06-27ASoC: atmel: Migrate to new style legacy DAI naming flagCharles Keepax1-0/+1
Change the legacy DAI naming flag from opting in to the new scheme (non_legacy_dai_naming), to opting out of it (legacy_dai_naming). These drivers appear to be on the CPU side of the DAI link and currently uses the legacy naming, so add the new flag.

2022-05-09ASoC: atmel-pdmic: Remove endianness flag on pdmic componentCharles Keepax1-1/+0
The endianness flag should have been removed when the driver was ported across from having both a CODEC and CPU side component, to just having a CPU component and using the dummy for the CODEC. The endianness flag is used to indicate that the device is completely ambivalent to the endianness of the data, typically due to the endianness being lost over the hardware link (ie. the link defines bit ordering). It's usage didn't have any effect when the driver had both a CPU and CODEC component, since the union of those equals the CPU side settings, but now causes the driver to falsely report it supports big endian. Correct this by removing the flag.

2020-07-10ASoC: atmel-pdmic: remove codec componentCodrin Ciubotariu1-69/+41
The CPU and the codec both are represented now as components, so for PDMIC we are registering two componenets with the same name. Since there is no actual codec, we will merge the codec component into the CPU one and use a dummy codec instead, for the DAI link. As a bonus, debugfs will no longer report an error when will try to create entries for both componenets with the same name.

2019-08-02ASoC: Remove dev_err() usage after platform_get_irq()Stephen Boyd1-5/+2
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).

2019-06-28ASoC: atmel: atmel-pdmic: consider CPU-Platform possibilityKuninori Morimoto1-1/+4
commit 7baf32e164da5d4 ("ASoC: atmel: atmel-pdmic: 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.

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_pdmic_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.
