ASoC: sunxi: use devm_platform_get_and_ioremap_resource()

2022-11-14T11:30:31Z

Convert platform_get_resource(), devm_ioremap_resource() to a single call to devm_platform_get_and_ioremap_resource(), as this is exactly what this function does.

ASoC: sunxi: sun4i-codec: set debugfs_prefix for CPU DAI component

2022-09-19T16:53:14Z

At present, succesfull probing of H3 Codec results in an error debugfs: Directory '1c22c00.codec' with parent 'H3 Audio Codec' already present! This is caused by a directory name conflict between codec components. Fix it by setting debugfs_prefix for the CPU DAI component.

ASoC: sunxi: sun4i-codec: silence misleading error in probe

2022-09-13T16:12:07Z

In the case when a codec device is probed before codec analog controls, snd_soc_register_card() returns -EPROBE_DEFER, resulting in a misleading error message sun4i-codec 1c22c00.codec: Failed to register our card even if the device is probed successfully later. Use dev_err_probe() to demote the above error to a debug message.

ASoC: Refactor non_legacy_dai_naming flag

2022-06-29T15:58:08Z

Merge series from Charles Keepax : Historically, the legacy DAI naming scheme was applied to platform drivers and the newer scheme to CODEC drivers. During componentisation the core lost the knowledge of if a driver was a CODEC or platform, they were all now components. To continue to support the legacy naming on older platform drivers a flag was added to the snd_soc_component_driver structure, non_legacy_dai_naming, to indicate to use the new scheme and this was applied to all CODECs as part of the migration. However, a slight issue appears to be developing with respect to this flag being opt in for the non-legacy scheme, which presumably we want to be the primary scheme used. Many codec drivers appear to forget to include this flag: grep -l -r "snd_soc_component_driver" sound/soc/codecs/*.c | xargs grep -L "non_legacy_dai_naming" | wc 48 48 556 Whilst in many cases the configuration of the DAIs themselves will cause the core to apply the new scheme anyway, it would seem more sensible to change the flag to legacy_dai_naming making the new scheme opt out. This patch series migrates across to such a scheme.

ASoC: sun50i-codec-analog: Add support for internal bias

2022-06-27T12:18:04Z

In order to properly bias headset microphones, there should be a pull-up resistor between pins HBIAS and MIC2P. This can be an external resistor, but the codec also provides an internal 2.2K resistor which is enabled by a register. This patch enables or disables the internal bias resistor based on a device tree property.

ASoC: sunxi: Remove now redundant non_legacy_dai_naming flag

2022-06-27T12:16:51Z

The ASoC core has now been changed to default to the non-legacy DAI naming, as such drivers using the new scheme no longer need to specify the non_legacy_dai_naming flag.

ASoC: sunxi: Migrate to new style legacy DAI naming flag

2022-06-27T12:16:26Z

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.
