The I2S controllers are programmed with an "attention" level of 4 DWORDs. This must match the configuration passed to the DMA driver, so that when they burst in data, they don't overflow the available FIFO space. Also, the burst size is relevant to the destination for playback, and source for capture, not vice-versa as originally written.

Use the dmaengine based Tegra APB DMA driver for data transfer between SPI fifo and memory in place of legacy Tegra APB DMA. Because generic soc-dmaengine-pcm uses the DMAs API based on dmaengine, using the exported APIs provided by this generic driver. The new driver is selected if legacy driver is not selected and new dma driver is enabled through config file.

If mic detect is left enabled and the WM8903 detects a status change, the WM8903 driver will make a callback against the free()d jack, which will cause a crash.

Stop open-coding the caching of the ctrl registers; instead, use regmap_update_bits() to update parts of the register from different places. The removal of the open-coded cache will allow controls to be created which touch registers, which will be necessary if any of these modules are converted to CODECs.

Prior to this patch, the CPU side of a DAI link was specified using a single name. Often, this was the result of calling dev_name() on the device providing the DAI, but in the case of a CPU DAI driver that provided multiple DAIs, it needed to mix together both the device name and some device-relative name, in order to form a single globally unique name. However, the CODEC side of the DAI link was specified using separate fields for device (name or OF node) and device-relative DAI name. This patch allows the CPU side of a DAI link to be specified in the same way as the CODEC side, separating concepts of device and device-relative DAI name. I believe this will be important in multi-codec and/or dynamic PCM scenarios, where a single CPU driver provides multiple DAIs, while also booting using device tree, with accompanying desire not to hard-code the CPU side device's name into the original .cpu_dai_name field. Ideally, both the CPU DAI and CODEC DAI loops in soc_bind_dai_link() would now be identical. However, two things prevent that at present: 1) The need to save rtd->codec for the CODEC side, which means we have to search for the CODEC explicitly, and not just the CODEC side DAI. 2) Since we know the CODEC side DAI is part of a codec, and not just a standalone DAI, it's slightly more efficient to convert .codec_name/ .codec_of_node into a codec first, and then compare each DAI's .codec field, since this avoids strcmp() on each DAI's CODEC's name within the loop. However, the two loops are essentially semantically equivalent. Signed-off-by: NStephen Warren <swarren@nvidia.com> Signed-off-by: NMark Brown <broonie@opensource.wolfsonmicro.com>

In kernel 3.6, Seaboard will only be supported when booting using device tree; the board files are being removed. Hence, remove the non-DT support for Seaboard and derivatives Kaen and Aebl from the audio driver. Harmony is the only remaining board supported by this driver when not using DT. This support is currently scheduled for removal in 3.7. Signed-off-by: NStephen Warren <swarren@nvidia.com> Signed-off-by: NMark Brown <broonie@opensource.wolfsonmicro.com>

By the time any widget callbacks could be called, if the GPIO ID they will manipulate is valid, it must have already been requested, or the card would have failed to probe or initialize. So, testing for GPIO validity is equivalent to testing whether the GPIO was successfully requested at this point in the code. Making this change will allow later patches to remove the gpio_requested variable. Signed-off-by: NStephen Warren <swarren@nvidia.com> Signed-off-by: NMark Brown <broonie@opensource.wolfsonmicro.com>

The headphone jack GPIOs are added/initialized in the DAI link's init() method, and hence in theory may not always have been added before remove() is called in some unusual cases. In order to prevent calling snd_soc_jack_free_gpios() if snd_soc_jack_add_gpios() had not been, the code kept track of the initialization state to avoid the free call when necessary. However, it appears that snd_soc_jack_free_gpios() is robust in the face of being called without snd_soc_jack_add_gpios() first succeeding, so there is little point manually tracking this information. Hence, remove the tracking code. All other machine drivers already operate this way.
