2023-03-20ASoC: rockchip: rockchip_spdif: Convert to platform remove callback ↵Uwe Kleine-König
returning void The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2022-06-27ASoC: rockchip: Migrate to new style legacy DAI naming flagCharles Keepax
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.

2016-07-18ASoC: rockchip: correct the spdif clkChris Zhong
The spdif mclk should be 128 times of sample rate, and there is a internal divider, the real rate of spdif mclk is mclk / (div + 1). Hence, the original driver always get the good frequency for 48000/96000/44100/192000. But for 32000, the mclk is incorrect, it should be 32000*128, but get 48000*128. Do not use the internal divider here, just set all mclk to 128 * sample rate directly. Signed-off-by: Chris Zhong <zyw@rock-chips.com> Signed-off-by: Mark Brown <broonie@kernel.org>

The rockchip spdif driver uses SIMPLE_DEV_PM_OPS to conditionally set its power management functions, but we get a warning about rk_spdif_runtime_resume being unused when CONFIG_PM is not set: sound/soc/rockchip/rockchip_spdif.c:67:12: error: 'rk_spdif_runtime_resume' defined but not used [-Werror=unused-function] This adds a __maybe_unused annotation so the compiler knows it can silently drop it instead of warning.

2015-12-12ASoC: rockchip: spdif: Set transmit data level to 16 samplesSjoerd Simons
Explicitly set the transmit data level on the transceiver to 16 samples rather then the default 0. This matches both the level set in the vendor kernel and the (seemingly very similar) i2s engine.
