Please check if the cd-gpios, vmmc-supply matches your board design.
hello Wayne.
vmmc-supply = <&max77620_ldo6>;
By the way, 3.3V is always input without controlling VDD.
However, the SD card cannot be detected and the following dmesg is output.

Is there something wrong with the device tree settings?
max77620_ldo6 is a regulator from 1.8v to 3.3.v. Please write a always-on regulator with voltage fixed in 3.3v.
hello Wayne.
Is it okay to set “regulator-min-microvolt” to “3300000” to fix the voltage to 3.3V as shown below?
max77620_ldo6: ldo6 {
regulator-name = "vddio-sdmmc3-ap";
maxim,active-fps-source = <MAX77620_FPS_SRC_NONE>;
maxim,active-fps-power-up-slot = <0>;
maxim,active-fps-power-down-slot = <7>;
/*regulator-min-microvolt = <1800000>;*/
regulator-min-microvolt = <3300000>;
regulator-max-microvolt = <3300000>;
regulator-enable-ramp-delay = <36>;
regulator-disable-ramp-delay = <674>;
regulator-ramp-delay = <100000>;
regulator-ramp-delay-scale = <200>;
};
In that case, the following log will not be output, but other errors will be output and the SD card will not be detected.
vddio-sdmmc3-ap: Restricting voltage, 3300000-1950000uV
Is the device tree setting wrong?
You can just check “sdmmc3” keywords on this nano forum and there would be bunches of same issue as yours.
Please refer to their case first. Also, just check the latest post first.

hello Wayne.
It is the result of “/sys/kernel/debug/mmc1/ios”.
clock: 0 Hz
vdd: 0 (invalid)
bus mode: 2 (push-pull)
chip select: 0 (don't care)
power mode: 0 (off)
bus width: 0 (1 bits)
timing spec: 0 (legacy)
signal voltage: 0 (3.30 V)
driver type: 0 (driver type B)
There are only 2 lines of mmc1 search result from your log. Which means the device is not provided by the power at all.
I have no idea what is vmmc-supply = <0x3b>; in your device tree here.
Please check this “0x3b” is matching your board design or not. This is a regulator phandle in somewhere else.

hello Wayne.
The source code I use comes from l4t 32.5.1 public sources (Jetson nano)
When I modify (/ hardware / NVIDIA / platform / t210 / porg / kernel DTS / tegra210-porg-p3448-common.dtsi), as shown in the following figure, the SD card cannot be read out.

When I modify (/ hardware / NVIDIA / platform / t210 / porg / kernel DTS / tegra210-porg-p3448-common.dtsi) as shown in the figure below, the SD card can be read out, but the reading and writing speed is very slow.

hello Wayne.
Set p3448_vdd_3v3_sd(regulator@3 above) to vmmc-supply and the following was added.
sd-uhs-sdr104;
sd-uhs-sdr50;
sd-uhs-sdr25;
sd-uhs-sdr12;
mmc-hs200-1_8v;
no-sdio;
no-mmc;
please assign the vqmmc-supply to max77620_ldo6. sd3 is 1.8v so has error here.
