关于device tree的问题

我看到FSL 官网上 linux-imx-3.10.17源码中 arch\arm\boot\dts\imx6qdl-sabresd.dts文件中关于ov5640的node，其中pwn-gpios = <&gpio1 16 1>; 这段描述中我没有找到相关的iomux，请问它是在哪进行iomux或pinctrl?
ov564x: ov564x@3c {
compatible = "ovti,ov564x";
reg = <0x3c>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_ipu1_2>;
clocks = <&clks 201>;
clock-names = "csi_mclk";
DOVDD-supply = <&vgen4_reg>; /* 1.8v */
AVDD-supply = <&vgen3_reg>; /* 2.8v, on rev C board is VGEN3,
on rev B board is VGEN5 */
DVDD-supply = <&vgen2_reg>; /* 1.5v*/
pwn-gpios = <&gpio1 16 1>; /* active low: SD1_DAT0 */
rst-gpios = <&gpio1 17 0>; /* active high: SD1_DAT1 */
csi_id = <0>;
mclk = <24000000>;
mclk_source = <0>;
};
