We may have pinmux settings for pinctrl device, like the following example: " &iomuxc { pinctrl-names = "default"; pinctrl-0 = <&pinctrl_hog_1>; imx6ul-evk { pinctrl_hog_1: hoggrp-1 { fsl,pins = < MX6UL_PAD_UART1_RTS_B__GPIO1_IO19 0x17059 /* SD1 CD */ MX6UL_PAD_GPIO1_IO05__USDHC1_VSELECT 0x17059 /* SD1 VSELECT */ MX6UL_PAD_GPIO1_IO09__GPIO1_IO09 0x17059 /* SD1 RESET */ MX6UL_PAD_SNVS_TAMPER0__GPIO5_IO00 0x80000000 >; }; [......] }; "
We should not only select pinctrl state for non pinctrl devices, we need also to handle pin mux settings such as pinctrl_log for pinctrl devices.
So at the end of probing process of pinctrl device, select the default state of pinctrl device.

V2: To pinctrl node, it is not root node. No need to check dev->parent.
