Sameer Pujar bbdfef7609 ASoC: tegra: Fix redundant PLLA and PLLA_OUT0 updates ... [ Upstream commit e765886249 ] Tegra audio graph card has many DAI links which connects internal AHUB modules and external audio codecs. Since these are DPCM links, hw_params() call in the machine driver happens for each connected BE link and PLLA is updated every time. This is not really needed for all links as only I/O link DAIs derive respective clocks from PLLA_OUT0 and thus from PLLA. Hence add checks to limit the clock updates to DAIs over I/O links. This found to be fixing a DMIC clock discrepancy which is suspected to happen because of back to back quick PLLA and PLLA_OUT0 rate updates. This was observed on Jetson TX2 platform where DMIC clock ended up with unexpected value.
