    ASoC: adau: Factor out shared PLL configuration code · 0eadaa9c
    Lars-Peter Clausen authored
    Multiple devices from the ADAU family share the same PLL structure and
    configuration register layout. Introduce a new helper module that can be
    used to calculated the PLL configuration registers based on a specified
    input frequency and the desired output frequency of the PLL.
    
    The ADAU1761/ADAU1781 and ADAU1373 drivers are updated to make use of this
    new helper module. But future drivers for additional devices from the ADAU
    family are also expected to make use of it.
    
    In anticipation of sharing more infrastructure code between different
    devices from the ADAU family the new module is called adau-utils.
