2024-10-10ASoC: loongson: Fix component check failed on FDT systemsBinbin Zhou
Add missing snd_soc_dai_link.platforms assignment to avoid soc_dai_link_sanity_check() failure. Fixes: d24028606e76 ("ASoC: loongson: Add Loongson ASoC Sound Card Support") Signed-off-by: Binbin Zhou <zhoubinbin@loongson.cn> Link: https://patch.msgid.link/6645888f2f9e8a1d8d799109f867d0f97fd78c58.1728459624.git.zhoubinbin@loongson.cn Signed-off-by: Mark Brown <broonie@kernel.org>
2024-09-10ASoC: loongson: Add the correct judgement returnTang Bin
Use the function dev_err_probe can simplify code, but the error return should not be deleted, that is unreasonable, thus fix it.

2024-09-09ASoC: loongson: Factor out loongson_card_acpi_find_device() functionBinbin Zhou
The operations for reading the cpu and codec nodes in loongson_card_parse_acpi() are similar, so we convert them into a simple helper function called loongson_card_acpi_find_device().

Deal with illegal conditions first and put the normal process code outside the if condition to improve code readability.

2024-09-09ASoC: loongson: Simplify with dev_err_probe()Binbin Zhou
Error handling in probe() can be a bit simpler with dev_err_probe(). Signed-off-by: Binbin Zhou <zhoubinbin@loongson.cn> Link: https://patch.msgid.link/07855aa6c290ec826d63e68b898e7f4afac5e30d.1725844530.git.zhoubinbin@loongson.cn Signed-off-by: Mark Brown <broonie@kernel.org>

2024-09-06ASoC: loongson: remove redundant variable assignmentsTang Bin
In the function loongson_asoc_card_probe, it is simpler to return the value of function devm_snd_soc_register_card directly.

2024-09-03ASoC: loongson: fix error releasetangbin
In function loongson_card_parse_of(), when get device_node 'codec' failed, the function of_node_put(codec) should not be invoked, thus fix error release.

The ASoC Sound Card driver can be compile tested with !CONFIG_OF making 'loongson_asoc_dt_ids' unused: sound/soc/loongson/loongson_card.c:200:34: warning: unused variable 'loongson_asoc_dt_ids' [-Wunused-const-variable] As krzysztof advice, we drop of_match_ptr so the device id can also be used on ACPI.

2023-06-19ASoC: loongson: fix error codes in loongson_card_parse_acpi()Dan Carpenter
The acpi_node_get_property_reference() function returns kernel error codes and not ACPI error codes. So, although it does not affect the compiled code, using the ACPI_FAILURE() macro is wrong. Secondly, if the is_acpi_device_node() function returns false, then we should return -ENOENT instead of returning success.

2023-06-15ASoC: loongson: Add Loongson ASoC Sound Card SupportYingkun Meng
The Loongson ASoC Sound Card is a general ASoC DAI Link driver that can be used for Loongson CPU DAI drivers and external CODECs. The driver supports the use of ACPI table to describe device resources. On loongson 7axxx platforms, the audio device is an ACPI device.
