+Subject: [PATCH 370/423] simple: add sound-dai-cells to I2S def
+
+Add '#sound-dai-cells = <0>;' to the I2S definition in
+bcm2708_common.dtsi
+
+Not having it specified, whilst not causing an issue right now with
+rpi-4.4.y, is going to cause an issue going forward with the use of
+simple-card driver. So it doesn't fall through the cracks, patch it
+in now.
+
+Hopefully Martin has taken care of getting a patch submitted for the
+upstream Pi dts, as it was he who first run into the issue with the
+current upstream kernel....
