These are the remaining dts patches from the series:
[PATCH v5 0/5] ASoC: add driver for Atmel I2S controller
v6 -> v7
- addressed some comments regarding pin conflicts;
v5 -> v6
- removed unnecessary phandles to audio PLL clock from the I2S nodes;
- using assigned clocks to set gclk as parent of i2smuxclk;
