2021-08-26ASoC: rockchip: spdif: Mark SPDIF_SMPDR as volatileSugar Zhang
This patch marks SPDIF_SMPDR as volatile to make it resaonable, which also requires marking it as readable, even though it isn't.

Disable the clocks in rk_spdif_probe when an error occurs after one of the clocks has been enabled previously. Found by Linux Driver Verification project (linuxtesting.org).

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>

2016-03-05ASoC: rockchip: use __maybe_unused to hide st_irq_syscfg_resumeArnd Bergmann
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. This fixes audio glitches when playing back at 192k rate. At the same time, fix a trivial typo in the TDL mask definition Signed-off-by: Sjoerd Simons <sjoerd.simons@collabora.co.uk> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-11-16ASoC: fix rockchip 64-bit build warningArnd Bergmann
The rk_spdif_probe uses the device match data as a token to identify a particular device, but accidentally casts a pointer to 'int', which is not portable, as gcc points out in this warning on arm64: rockchip_spdif.c: In function 'rk_spdif_probe': rockchip_spdif.c:283:6: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] This changes the logic to compare two pointer values instead, using the same cast that was used for initializing the value in the first place.
