Interfacing IMX8QXP with IW611

[Rohith04]

Hi Team,

In our target board, we are using ENET pins as SDIO lines. Please find the attached screenshot of the schematics and the DTSI file. These SDIO lines are interfaced with IW611 and in this scenario, we are unable to detect the High-speed mode and ultra-high-speed mode. Please check and let us know if there is any mistake.

Hi,

Thank you for your interest in NXP Semiconductor products,

You can try the option 2 (based on you have tried option 1 already).

Hi,
Thanks for your reply
Initially, we had tried with these entries only since the issues were resolvable.
&usdhc2 {
assigned-clocks = <&clk IMX_SC_R_SDHC_1 IMX_SC_PM_CLK_PER>;
assigned-clock-rates = <200000000>;
pinctrl-names = "default", "state_100mhz", "state_200mhz";
pinctrl-0 = <&pinctrl_usdhc2>, <&pinctrl_usdhc2_gpio>;
pinctrl-1 = <&pinctrl_usdhc2>, <&pinctrl_usdhc2_gpio>;
pinctrl-2 = <&pinctrl_usdhc2>, <&pinctrl_usdhc2_gpio>;
bus-width = <4>;

enable-sdio-wakeup;
status = "okay";
