clk: sunxi-ng: sun4i: Use sigma-delta modulation for audio PLL The audio blocks require specific clock rates. Until now we were using the closest clock rate possible with integer N-M factors. This resulted in audio playback being slightly slower than it should be. The vendor kernel gets around this (for newer SoCs) by using sigma-delta modulation to generate a fractional-N factor. As the PLL hardware is identical in most chips, we can back port the settings from the newer SoC, in this case the H3, onto the A10 and A20.

* With sigma-delta modulation for fractional-N on the audio PLL,
* we have to use specific dividers. This means the variable divider
* can no longer be used, as the audio codec requests the exact clock
* rates we support through this mechanism. So we now hard code the
* variable divider to 1. This means the clock rates will no longer
* match the clock names.

clk: sunxi-ng: sun4i: Use sigma-delta modulation for audio PLL The audio blocks require specific clock rates. Until now we were using the closest clock rate possible with integer N-M factors. This resulted in audio playback being slightly slower than it should be. The vendor kernel gets around this (for newer SoCs) by using sigma-delta modulation to generate a fractional-N factor. As the PLL hardware is identical in most chips, we can back port the settings from the newer SoC, in this case the H3, onto the A10 and A20.

clk: sunxi-ng: sun4i: Set VCO and PLL bias current to lowest setting The default mid-level PLL bias current setting interferes with sigma delta modulation. This manifests as decreased audio quality at lower sampling rates, which sounds like radio broadcast quality, and distortion noises at sampling rates at 48 kHz or above. Changing the bias current settings to the lowest gets rid of the noise.

clk: sunxi-ng: sun4i: Use sigma-delta modulation for audio PLL The audio blocks require specific clock rates. Until now we were using the closest clock rate possible with integer N-M factors. This resulted in audio playback being slightly slower than it should be. The vendor kernel gets around this (for newer SoCs) by using sigma-delta modulation to generate a fractional-N factor. As the PLL hardware is identical in most chips, we can back port the settings from the newer SoC, in this case the H3, onto the A10 and A20.
