   4 Subject: [PATCH 1293/1295] overlays: Sets i2s_clk_producer as default for
   5  Hifiberry DACplusADC
   6
   7 As we have never released a (standard) DACplusADC board with onboard
   8 clocks, we can simply use a fixed setup avoiding incompatibilities
   9 with Pi5 during driver init. Setting 'hifiberry-dacplusadc,slave' in
  10 the overlays disables the failing clock probing mechanism.
  11
  12 Removes 'slave' parameter description from README which is still
  13 supported but not needed.
