And the manuals don't have anything on the SPDIF clock, so I can't comment on it. > usb_clk: clk@01c200cc { > #clock-cells = <1>; > #reset-cells = <1>; > @@ -352,6 +375,22 @@ > clock-output-names = "spi3"; > }; > > + iis1_clk: clk@01c200d8 { > + #clock-cells = <0>; > + compatible = "allwinner,sun4i-a10-mod1-clk"; > + reg = <0x01c200d8 0x4>; > + clocks = <&pll2 0>, <&pll2 1>, <&pll2 2>, <&pll2 3>; > + clock-output-names = "iis1"; > + }; > + > + iis2_clk: clk@01c200dc { > + #clock-cells = <0>; > + compatible = "allwinner,sun4i-a10-mod1-clk"; > + reg = <0x01c200dc 0x4>; > + clocks = <&pll2 0>, <&pll2 1>, <&pll2 2>, <&pll2 3>; > + clock-output-names = "iis2"; > + }; > + > codec_clk: clk@01c20140 { > #clock-cells = <0>; > compatible = "allwinner,sun4i-a10-codec-clk"; > -- Apart from the title and the clock orders, everything looks good.

Otherwise, beside Chen-Yu's comment, it looks fine. Maxime

We do have this much SPDIF doc. http://linux-sunxi.org/SPDIF Based on the Allwinner code I see no reason to think that the SPDIF clock varies from any of the other audio clocks.

I'd say whatever is the most common, this is why we ended up using i2c instead of allwinner's twi, pinctrl over port controller, etc. Maxime
