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";

  };

};

Could you mention how you compiled/ go this dts file from? Are you using Type 1MW? if yes, have you checked with murata on setting the particular phandler for mmc power sequence?

Warm Regards,
