snd_soc_dapm_new_widgets will call dapm_power_widgets at the end, so there is no need to call snd_soc_dapm_sync after snd_soc_dapm_new_widgets. Signed-off-by:

While I2S/TDM/AC97 DAI is built-in, others are compiled as modules, SND_BF5XX_SOC_SPORT will be module, then DAI can't get some symbols. Except that, SND_BF5XX_AC97 depends on SND_BF5XX_SOC_AC97 too. Signed-off-by:

Changelog: 1. I2S module of EP93xx should be feed by 32bit DMA transfers. This is hardware limitation and that's the way original Cirrus's driver worked. This will fix distorted sound playback and make capture actually work in present ep93xx drivers. I've found, that author of code, on which modern ep93xx-i2s.c and ep93xx-pcm.c are based, had faced this problem also in 2007: http://blog.gmane.org/gmane.linux.ports.arm.cirrus/month=20070101/page=3 Now SoC code uses his developments, but not overcomes the hardware issues. Some details from EP93xx users guide: Both I2S transmitter and receiver have similar 16x32bit FIFO, where they store 8 samples for both left and right channels. The FIFO is always 32bit wide and should be properly aligned if you use samples of other width. Transmitter and receiver have configuration registers for selection of I2S word length (16, 24, 32). They are I2STXWrdLen and I2SRXWrdLen. Yes, EP93xx DMA can do byte, word and quad-word transfers. The width for transfers to and from peripherals is selected by particular module configuration. Lucky AC97 module has such configuration: AC97RXCRx registers, bit CM (Compact mode enable) switches between 16 and 32 bit samples. AC97TXCRx registers have the same bits for transmitters. ep93xx-ac97.c enables this compact mode and so has all the rights to use S16_LE format. No one has found such a configuration in I2S module until now in any Cirrus manuals. I2S module always feeds it's 32bit wide FIFO with 32bit samples consecutively for left and right channels. You cannot use 32-bit DMA transfers to transfer two 16-bit samples. So we can use two formats for AC97, but should remove all but S32_LE for I2S. Always using 32 bit chunks is not a problem for I2S, the codec I use uses less bits too (24), it's permitted by I2S standard. In proposed patch formats list shortened to just S32_LE, this makes all the DMA transactions right, while ALSA will do all sample format translation for us. 2. Incorrect setting of LRCLK (2 times slower) in original ep93xx-i2s.c masks the first problem. DMA takes two 16 bit samples instead of one, overall sound speed seems to be normal, but you get actually 4000 sampling rate instead of requested 8000 and therefore some noise... This is also the reason why the capture function not worked at all in this driver... If we take a look into I2S specification, we will figure that LRCLK MUST be equal to sample rate, if we are talking about stereo (in mono too, but it's not our case at all). In proposed patch SCLK and LRCLK rates are corrected, assuming we always send 32 bits * 2 channels to codec. Signed-off-by:

That config variable doesn't exist in the mainline kernel, and hence the dependency shouldn't either. In linux-tegra-2.6.36, the dependency did exist to avoid a conflict with the old non-ALSA Tegra I2S driver. However, this isn't and won't be upstreamed. Signed-off-by:

These changes are needed to keep up with the changes in the MFD core and V4L2 parts of the wl1273 FM radio driver. Use function pointers instead of exported functions for I2C IO. Also move all preprocessor constants from the wl1273.h to include/linux/mfd/wl1273-core.h. Signed-off-by:

Currently the soc_probe initializes the card hence it does the card list initialzation. But if machines directly register the card they would need to do these steps, so putting them as inline would save lot of code This patch adds an inline to do list initialzation Signed-off-by:

In soc_remove() the card resources are cleaned up. This can also be done in card_unregister() This patch move this cleanup into a new function and calls it from card_unregister. This paves way for further work to allow card registartion from machine. Signed-off-by:

A recent discussion on linux-arm-kernel noted that the value returned by clk_get_sys is an opaque token, and not strictly a pointer; it is meaningful only to the clock API, clients should not dereference the value, and the clock API must accept any non-IS_ERR value it returned. Hence, only IS_ERR is appropriate to interpret the result, not IS_ERR_OR_NULL. I checked that clk_get_sys in both ASoC's for-next and Tegra's for-next do behave as described; NULL is not returned in the case of error. Signed-off-by:

Ensure that all calls to readable_register()/volatile_register() go via the snd_soc_codec function pointers. If the default register access table has been given but no functions for handling readable()/volatile() registers, use the default ones provided by soc-cache. Signed-off-by:

For common scenarios, device drivers can provide a table of all the registers that are at least either readable/writable/volatile. The idea is that if a register lookup fails, all of its read/write/vol members will be zero and will be treated as default. This also reduces the size of the register access array. Signed-off-by:

The L/R LOM line can be invertined side of the corresponding DAC, or inverted from the corresponding LOP. Add control for user space to select the source of the LOM inversion. When only the analog bypass is enabled, and the LOM is inverted from DAC output, we need to power the corresponding DAC. Signed-off-by:
