This patch adds GPIO jack detection to Nokia N900/RX-51. At the moment only SND_JACK_VIDEOOUT type is reported. More types could be reported after getting more audio features supported and necessary drivers integrated for implementing automated accessory detection. Signed-off-by:

Nokia RX-51/N900 has multifunction 4-pole audio-video jack that can be used as headphone, headset or audio-video connector. This patch implements the control 'Jack Function' which is used to select the desired function. At the moment only TV-out without audio is supported. Signed-off-by:

in tlv320aic23_set_bias_level, for the case SND_SOC_BIAS_ON, the comment says "vref/mid, osc on, dac unmute" but the code doesn't clear the corresponding bits, thus when resuming, several bits are not cleared preventing the codec from working. in tlv320aic23_suspend, clearing the active register is not needed as it will be done by tlv320aic23_set_bias_level, when setting bias to SND_SOC_BIAS_OFF Signed-off-by:

After mass production started it was found that several boards exhibit noise problems during sound playback. After some investigation it was determined that CLKX polarity is set incorrectly, and even if most boards can tolerate the wrong setting, there are some that don't. Fix polarity setup in the board file. As the clock settings for input and output now match, merge in and out functions and structures to simplify code. Signed-off-by:

When SX_TLV widgets are read, if the gain is set to a value below 0dB, the mixer control is erroniously read as being at maximum volume. The value read out of the CODEC register is never sign-extended, and when the minimum value is subtracted (read; added, since the minimum is negative) the result is a number greater than the maximum allowed value for the control, and hence it saturates. Solution: Mask the result so that it "wraps around", emulating sign-extension. Signed-off-by:

The config option SND_FSI_AK4642 selects SND_SOC_AK4642 which in turn enables the compilation of ak4642.c - however this codec uses I2C to communicate with the HW. Same applies to DA7210. Consequently when I2C is not set, the compilation fails [1] This patch fixes this issues, by adding a depencdency on the related HW- controller. Signed-off-by:

On DA830/OMAP-L137 and DA850/OMAP-L138 SoCs, the McASP peripheral has FIFO support. This FIFO provides additional data buffering. It also provides tolerance to variation in host/DMA controller response times. More details of the FIFO operation can be found at http://focus.ti.com/general/docs/lit/getliterature.tsp?literatureNumber=sprufm1&fileType=pdf Existing sequence of steps for audio playback/capture are: a. DMA configuration b. McASP configuration (configures and enables FIFO) c. Start DMA d. Start McASP (enables FIFO) During McASP configuration, while FIFO was being configured, FIFO was being enabled in davinci_hw_common_param() function of sound/soc/davinci/davinci-mcasp.c file. This generated a transmit DMA event, which gets serviced when DMA is started. https://patchwork.kernel.org/patch/84611/ patch clears the DMA events before starting DMA, which is the right thing to do. But this resulted in a state where DMA was waiting for an event from McASP (after step c above), but the event which was already there, has got cleared (because of step b above). The fix is not to enable the FIFO during McASP configuration as FIFO was being enabled as part of McASP start. Signed-off-by:

Upper threshold is used in mode7 of DAC33. Instead of hard wired UTHR, add control to change the upper threshold value. Changing upper threshold is not allowed when the playback is already running, since wrongly timed change in the UTHR can cause problems with the codec. With this control the length of the burst in mode7 can be changed. Signed-off-by:

OMAP McBSP FIFO is word structured: McBSP2 has 1024 + 256 = 1280 word long buffer, McBSP1,3,4,5 has 128 word long buffer This means, that the size of the FIFO depends on the McBSP word size configuration. For example on McBSP3: 16bit samples: size is 128 * 2 = 256 bytes 32bit samples: size is 128 * 4 = 512 bytes It is simpler to place constraint for buffer and period based on channels. McBSP3 as example again (16 or 32 bit samples): 1 channel (mono): size is 128 frames (128 words) 2 channels (stereo): size is 128 / 2 = 64 frames (2 * 64 words) 4 channels: size is 128 / 4 = 32 frames (4 * 32 words) Use the second method to place hw_rule on buffer size, and in threshold mode to period size.

Use the actual FIFO size in words as buffer_size on OMAP3. Change the threshold configuration to use 1 based numbering, when specifying the allowed threshold maximum or the McBSP threshold value. Set the default maximum threshold to (buffer_size - 0x10) intialy. >From users of McBSP, now it is expected to use this method. Asking for threshold 1 means that the value written to threshold registers are going to be 0, which means 1 word threshold. Signed-off-by:
