The driver supports the use of ACPI table to describe device resources. On loongson 7axxx platforms, the audio device is an ACPI device.
I'm not seeing any ACPI IDs added here, this is all DT other than this:
I use the special ACPI ID "PRP0001", it provides a means to use the existing
DT-compatible device identification in ACPI.
As described in the document "ACPI Based Device Enumeration".
- if (has_acpi_companion(&pdev->dev)) {
device_property_read_string(&pdev->dev, "codec-name",&codec_name);for (i = 0; i < card->num_links; i++)loongson_dai_links[i].codecs->name = codec_name;device_property_read_string(&pdev->dev, "codec-dai-name",&codec_dai_name);for (i = 0; i < card->num_links; i++)loongson_dai_links[i].codecs->dai_name = codec_dai_name;- } else {
which doesn't look *great* from an ACPI point of view TBH. I thought there were now some (semi?) standard ACPI bindings these days to support referencing other devices better?
Got it! I will rewrite this part.
