2016-06-09ASoC: adau: Factor out shared PLL configuration codeLars-Peter Clausen1-0/+7
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.
