   4 Subject: [PATCH 1268/1295] ASoC: DACplusADCPro - fix 16bit sample support in
   5  clock consumer mode
   6
   7 The former code did not adjust the physical sample width when in
   8 clock consumer mode and has taken the fixed 32 bit default. This
   9 has caused the audio to be played at half its frequency due to
  10 the fixed bclk_ratio of 64.
  11
  12 Problem appears only on PI5 as on the former PIs the I2S module
  13 did simply run at fixed 64x rate.
