ASoC: sun4i-codec: Set quirks.playback_only for H616 codec

2026-07-14T14:23:08Z

The H616 codec does not have capture capabilities. Set the .playback_only quirks flag to denote this. This was somehow missing from the original driver patch, even though the patch prior to it in the series added this quirk.

ASoC: sun4i-codec: add h616 card long_name

2025-03-13T22:50:07Z

Adding jack detection requires sound servers to act on the emitted events, which are described by ALSA Use Case Manager configurations in userspace. These configurations include the long card name in the file path (falling back to card->name if this is not present), so add a long card name for the H616 without spaces, making UCM referencing easier. The corresponding ALSA UCM patch is here (now merged): https://github.com/alsa-project/alsa-ucm-conf/pull/491 Signed-off-by: Ryan Walklin -- Changelog v1..v2: - Separate patch for card->long_name - Note UCM patch link Changelog v2..v3: - Add card->long_name rather than change existing card->name Link: https://patch.msgid.link/20250214220247.10810-6-ryan@testtoast.com Signed-off-by: Mark Brown

ASoC: sun4i-codec: support hp-det-gpios property

2025-03-13T22:50:06Z

Add support for GPIO headphone detection with the hp-det-gpios property. In order for this to properly disable the path upon removal of headphones, the output must be labelled Headphone which is a common sink in the driver. Describe a headphone jack and detection GPIO in the driver, check for a corresponding device tree node, and enable jack detection in a new machine init function if described.

ASoC: sun4i-codec: correct dapm widgets and controls for h616

2025-03-13T22:50:05Z

The previous H616 support patch added a single LINEOUT DAPM pin switch to the card controls. As the codec in this SoC only has a single route, this seemed reasonable at the time, however is redundant given the existing DAPM codec widget definitions controlling the digital and analog sides of the codec. It is also insufficient to describe the scenario where separate components (muxes, jack detection etc) are used to modify the audio route external to the SoC. For example the Anbernic RG(##)XX series of devices uses a headphone jack detection switch, GPIO-controlled speaker amplifier and a passive external mux chip to route audio. Remove the redundant LINEOUT card control, and add a Speaker pin switch control and Headphone DAPM widget to allow control of the above hardware.

ASoC: sun4i-codec: Use new devm clk and reset APIs

2025-01-14T14:31:14Z

Clean up error handling by using the new devm_ clock and reset functions. This should make it easier to add new code, as we can eliminate the "goto ladder" in probe().

ASoC: sun4i-codec: support allwinner H616 codec

2024-10-24T12:22:18Z

The H616 SoC codec is playback-only with a single line-out route, and has some register differences from prior codecs. Add the required compatible string, registers, quirks, DAPM widgets, codec controls and routes, based on existing devices and the H616 datasheet.

ASoC: sun4i-codec: Add playback only flag to quirks

2024-10-24T12:22:17Z

Some devices only have the playback side of the codec implemented so add a quirk to check for this. This flag is only required internally within the codec driver, as the DAI is configured for playback only (capture disabled) separately in the create_card() function for these devices.
