   4 Subject: [PATCH] simple: add sound-dai-cells to I2S def
   5
   6 Add '#sound-dai-cells = <0>;' to the I2S definition in
   7 bcm2708_common.dtsi
   8
   9 Not having it specified, whilst not causing an issue right now with
  10 rpi-4.4.y, is going to cause an issue going forward with the use of
  11 simple-card driver. So it doesn't fall through the cracks, patch it
  12 in now.
  13
  14 Hopefully Martin has taken care of getting a patch submitted for the
  15 upstream Pi dts, as it was he who first run into the issue with the
  16 current upstream kernel....
