Hi Team,
In the DTS node property mwifiex mentioned below, the default operating frequency is 25 MHz. I would like to update my SDMMC1 clock to 50 MHz and require assistance with configuring it accordingly. Could you please provide me with details or reference documents?
&sdmmc1 {
pinctrl-names = "default", "opendrain", "sleep";
pinctrl-0 = <&sdmmc1_pins_mx>;
pinctrl-1 = <&sdmmc1_opendrain_pins_mx>;
pinctrl-2 = <&sdmmc1_sleep_pins_mx>;
non-removable;
st,neg-edge;
bus-width = <4>;
vmmc-supply = <&scmi_vdd_sd>;
mmc-pwrseq = <&wifi_pwrseq>;
mmc-ddr-3_3v;
#address-cells = <1>;
#size-cells = <0>;
status = "okay";
mwifiex: mwifiex@1 {
compatible = "marvell,sd8978";
reg = <1>;
interrupt-parent = <&gpiof>;
interrupts =
//marvell,wakeup-pin = <3>; /* FIXME: check */
};
};
Regards,

What MCU? What Board?
Tag properly and post to right subforum.

Hi Tesla DELorean,
I am using MPU not MCU. STM32MP133C
