2014-12-30ASoC: fsl_spdif: Use dev_name() for registering the irqFabio Estevam
The 'name' array is currently stored inside the fsl_spdif_priv private structure only for registering the interrupt name. This can be simplified by registering it with dev_name() instead.

2014-07-31ASoC: fsl_spdif: Add stream names for DPCM usageNicolin Chen
DPCM needs extra dapm routes in the machine driver to route audio between Front-End and Back-End. In order to differ the stream names in the route map from CODECs, we here add specific stream names to SPDIF driver so that we can implement ASRC via DPCM to it.

2014-06-09ASoC: fsl_spdif: Fix integer overflow when calculating divisorsAnssi Hannula
The calculation code does u64 = (u32 - u32) * 100000; The 64 bits are of no help here as the type is casted only after the multiplication, and therefore the result may overflow, possibly causing inoptimal or wrong clock setup in an unfortunate case (the maximum result value of the first substraction is currently 47999). Fix the code to cast before multiplication. Signed-off-by: Anssi Hannula <anssi.hannula@iki.fi> Acked-by: Nicolin Chen <Guangyu.Chen@freescale.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-06-09ASoC: fsl_spdif: Fix incorrect usage of regmap_read()Nicolin Chen
We should not copy the return value into this val since it's supposed to get the value of the register not the success result of regmap_read(). Thus fix it. Signed-off-by: Nicolin Chen <Guangyu.Chen@freescale.com> Signed-off-by: Mark Brown <broonie@linaro.org>

2014-05-05ASoC: fsl_spdif: Add sysclk df support to derive txclk from sysclkNicolin Chen
The sysclk is one the clock sources that could be selected to derive tx clock. But the route for sysclk is a bit different that it does not only contain txclk df divider but also have an extra sysclk df. So this patch mainly adds syclk df configuration support so as to let the driver be able to get clock from sysclk.

2014-05-05ASoC: fsl_spdif: Use clk_set_rate() for spdif root clock onlyNicolin Chen
The clock mux for the Freescale S/PDIF controller has eight clock sources while most of them are from other moudles and even system clocks that do not allow a rate-changing operation. So we here only allow the clk_set_rate() and clk_round_rate() happened to spdif root clock, the private clock for S/PDIF controller.

2014-04-29ASoC: fsl_spdif: Fix clock source for rxclk rate measurementNicolin Chen
The rxclk rate actually uses sysclk, ipg clock for example, as its reference clock to calculate it. But the driver currently doesn't pass a correct clock source. So fix it. Signed-off-by: Nicolin Chen <Guangyu.Chen@freescale.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-04-24ASoC: fsl_spdif: Add core clock control for DMA accessNicolin Chen
Regmap is able to enable/disable the core clock automatically each time it's going to access the registers. But for DMA cases during playback or recording, it's totally beyong control of regmap. So we have to open the clock manually. Signed-off-by: Nicolin Chen <Guangyu.Chen@freescale.com> Signed-off-by: Mark Brown <broonie@linaro.org>
