    Device Tree of CYW43455 with i.MX8M Mini

    MaMa_4565926

      Hi All,

       

      We would like to implement dts of  CYW43455 on i.MX8M Mini.

      After refering to the following post >> CYW43455 with i.MX8M Mini, we find "usdhc1_pwrseq_wifibt" is not defined, could you help us what is the content of "usdhc1_pwrseq_wifibt" ? Thanks for your help.

       

      DTS:

      pinctrl_wlan: wlangrp {

        fsl,pins = <

          MX8MM_IOMUXC_GPIO1_IO00_ANAMIX_REF_CLK_32K   0x141

          MX8MM_IOMUXC_SD1_RESET_B_GPIO2_IO10           0x1c4   /* WL_REG_ON */

          MX8MM_IOMUXC_SD1_DATA5_GPIO2_IO7              0xC6    /* BT_DEV_WAKE */

        >;

      };

       

      &usdhc1 {

      #address-cells = <1>;

      #size-cells = <0>;

      pinctrl-names = "default", "state_100mhz", "state_200mhz";

      pinctrl-0 = <&pinctrl_usdhc1>, <&pinctrl_wlan>;

      pinctrl-1 = <&pinctrl_usdhc1_100mhz>, <&pinctrl_wlan>;

      pinctrl-2 = <&pinctrl_usdhc1_200mhz>, <&pinctrl_wlan>;

      bus-width = <4>;

      pm-ignore-notify;

      keep-power-in-suspend;

      non-removable;

      status = "okay";

      enable-sdio-wakeup;

      wifi-host;

      mmc-pwrseq = <&usdhc1_pwrseq_wifibt>;

        brcmf: bcrmf@1 {

        reg = <1>;

        compatible = "brcm,bcm4329-fmac";

        };

      };
