2016-03-05ASoC: rockchip: add bindings for spdif controllerSugar Zhang1-3/+10
this patch add compatible for rk3366/rk3368/rk3399 spdif, these three spdifs share the same type. Signed-off-by: Sugar Zhang <sugar.zhang@rock-chips.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2016-03-05ASoC: rockchip: use __maybe_unused to hide st_irq_syscfg_resumeArnd Bergmann1-2/+2
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 Simons2-3/+5
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: rockchip: i2s: compatible with different chipsSugar Zhang1-5/+15
there maybe more than one i2s module inside chip, and these i2s modules have different channels features. for example: there are 3 i2s in rk3066, one support 8 channels playback and 2 channels capture, but the others only support 2 channels playback and 2 channels capture. in order to compatible with these various chips, we add playback and capture property to specify these values. there are default channels configuration in driver: 8 channels playback and 2 channels capture. if not add property, we use the default values.

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.

This patch sets the dividers autonomously. when i2s works on master mode, and sample rates changed. We need to change bclk and lrck at the same time for cpu internal side. As the input source clock to the module is MCLK_I2S, and by the divider of the module, the clock generator generates SCLK and LRCK to transmitter and receiver.

Currently, CONFIG_SND_SOC_ROCKCHIP_I2S could also be selected without having CONFIG_SND_SOC_ROCKCHIP enabled. As this makes no sense, a Kconfig dependency is added to CONFIG_SND_SOC_ROCKCHIP_I2S. This will make the item visible only if CONFIG_SND_SOC_ROCKCHIP is enabled. Additionally, as the code connected to CONFIG_SND_SOC_ROCKCHIP_I2S depends on CONFIG_SND_SOC_GENERIC_DMAENGINE_PCM, the dependency is moved to reflect this more clearly.
