[RFC patch 0/5] Support BCLK input clock in tlv320aic31xx

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The tlv320aic31xx codec allows using BCLK as the input clock for PLL,
deriving all the frequencies through a set of divisors.

In this case, codec sysclk is determined by the hwparams sample
rate/format. So its frequency must be updated from the codec itself when
these are changed.

This patchset modifies the tlv320aic31xx driver to update its sysclk if
BCLK is used as the input clock. This allows to be used by the generic
fsl-asoc-card, without having to add a specific driver.

Ariel D'Alessandro (5):
  ASoC: tlv320aic31xx: Fix typo in BCLK clock name
  ASoC: tlv320aic31xx: Add support for pll_r coefficient
  ASoC: tlv320aic31xx: Add divs for bclk as clk_in
  ASoC: tlv320aic31xx: Handle BCLK set as PLL input configuration
  ASoC: fsl-asoc-card: Support fsl,imx-audio-tlv320aic31xx codec
