2013-08-05ASoC: kirkwood: merge struct kirkwood_dma_priv with struct kirkwood_dma_dataRussell King
Merge these two structures together; nothing other than the I2S and DMA driver makes use of struct kirkwood_dma_data, and it's not like struct kirkwood_dma_data is really just used to convey DMA specific data to the backend; it's more a general shared structure between the two halves. This will later allow kirkwood-dma.c and kirkwood-i2s.c to be merged together. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by: Mark Brown <broonie@linaro.org>
2013-07-16ASoC: kirkwood-i2s: fix a compilation warningJean-Francois Moine
In the function kirkwood_set_rate, when the rate cannot be satisfied by the internal nor by an external clock, the clock source in undefined: warning: ‘clks_ctrl’ may be used uninitialized in this function The ALSA subsystem should never gives such a rate because: - the rates with the internal clock are limited to 44.1, 48 and 96 kHz as specified by the kirkwood_i2s_dai structure, - the other rates are proposed in the structure kirkwood_i2s_dai_extclk only when the external clock is present. In case of programming error (bad rate for internal clock and no external clock), the function will simply cause a backtrace.

2013-07-16ASoC: kirkwood-i2s: Inline KIRKWOOD_I2S_RATESMark Brown

2012-11-21ASoC: kirkwood-dma: remove channel restrictionsRussell King
This is part of a patch found in Rabeeh Khoury's git tree for the cubox. With SPDIF passthrough, we are not restricted to just two channels of audio; we can support however many channels the non-audio stream can itself support. In any case, kirkwood-dma is not involved in the format selection. So yet rid of this restriction.

2012-11-21ASoC: kirkwood-i2s: add support for external clock ratesRussell King
This is part of a patch found in Rabeeh Khoury's git tree for the cubox, and cleaned up by me. Some platforms provide an external clock which can be used to allow other sample rates to be selected. Provide support for this. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-11-21ASoC: kirkwood-dma: remove restriction on sample ratesRussell King
This is part of a patch found in Rabeeh Khoury's git tree for the cubox. The kirkwood DMA hardware for ASoC does not impose any restrictions on the sample rates available, so it's silly to impose an artificial set in the DMA code. The restrictions come from the availble clocks to the I2S module, which are already handled in the I2S part of the driver.

2012-11-21ASoC: kirkwood-i2s: more pause-mode fixesRussell King
Don't even momentarily set the pause status when starting the channel; if we do, we should check the busy bit to ensure that we comply with the spec. In any case, it isn't necessary; we will not active on a START event so there is no need to pause the DMA.

2012-11-21ASoC: kirkwood-i2s: fix DMA underrunsRussell King
Stress testing the driver with multiple start/stop events causes kirkwood-dma to report underrun errors (which used to cause the kernel to lock up solidly). This is because kirkwood-i2s is not respecting the restrictions imposed on clearing the 'pause' bit. Follow what the spec says; the busy bit must be read as being clear twice before the pause bit can be released. This solves the underruns. However, it has been noticed that the busy bit occasionally does not clear itself, hence the waiting is bounded to 5ms maximum to avoid a new reason for the kernel to lockup.

2012-11-21ASoC: kirkwood-i2s: fix DCO lock detectionRussell King
This is part of a patch found in Rabeeh Khoury's git tree for the cubox, which is further attributed to Sebastian Hesselbrath. Rather than masking the KIRKWOOD_DCO_SPCR_STATUS register contents against the registers virtual address, let's actually use the bit definition for the locked status, as required in the documentation.

2012-11-21ASoC: kirkwood-dma: don't ignore other irq causes on errorRussell King
Ignoring the real cause of the interrupt is not a good idea; this behaviour has been observed to bring Dove platforms to silently lockup. Instead, on error fall through to the normal interrupt processing. This is especially important on Dove platforms as errors are handled separately, and allows us to clear down the real cause of the interrupt.

2012-11-21ASoC: kirkwood-dma: fix use of virt_to_phys()Russell King
This is part of a patch found in Rabeeh Khoury's git tree for the cubox. You can not use virt_to_phys() on the address returned from dma_alloc_coherent(); it may not be part of the kernel direct-mapped memory. Fix this to use the DMA address instead.
