+* Rockchip I2S controller
+
+The I2S bus (Inter-IC sound bus) is a serial link for digital

+
+- compatible: should be one of the followings
+ - "rockchip,rk3066-i2s": for rk3066
+ - "rockchip,rk3188-i2s", "rockchip,rk3066-i2s": for rk3188

+- reg: physical base address of the controller and length of memory mapped

+- interrupts: should contain the I2S interrupt.
+- #address-cells: should be 1.
+- #size-cells: should be 0.
+- dmas: DMA specifiers for tx and rx dma. See the DMA client binding,
+ Documentation/devicetree/bindings/dma/dma.txt
+- dma-names: should include "tx" and "rx".

Can these be quoted for consistency with clock-names below?

Can this be written in terms of clock-names, e.g.
- clocks: a list of phandle + clock-specifer pairs, one for each entry
in clock-names.
