dm: core: device: set pinctrl state for pinctrl device
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.
