Hi,
Did anyone observing error -110 and -84 during boot on rk3288 target?
full log here[1] and used dts node is[2].
Proper card detection is done, once we insert after console came-up
# [ 39.635614] mmc0: card 59b4 removed
[ 40.645537] mmc_host mmc0: Bus speed (slot 0) = 400000Hz (slot req
400000Hz, actual 400000HZ div = 0)
[ 41.004559] mmc_host mmc0: Bus speed (slot 0) = 50000000Hz (slot
req 50000000Hz, actual 50000000HZ div = 0)
[ 41.015553] mmc0: new high speed SDXC card at address 59b4
[ 41.022015] mmcblk0: mmc0:59b4 MS 59.1 GiB
[ 41.028458] mmcblk0: p1 p2
Any help?

-100 is -ETIMEDOUT and -84 is CRC error. So that seems much likely HW
relevant. Have you check the SI of SD slot?
You don't enable UHS mode so the tuning process won't help.
But rockchip platforms have a default setting for sample delay.
See rockchip,default-sample-phase and try add some sample delay.
FYI: Documentation/devicetree/bindings/mmc/rockchip-dw-mshc.txt

Does it means Serial Interface of SD, if yes. I've been added sdio0
for the same.
&sdio0 {
bus-width = <4>;
disable-wp;
non-removable;
pinctrl-names = "default";
pinctrl-0 = <&sdio0_bus4>, <&sdio0_cmd>, <&sdio0_clk>;
vmmc-supply = <&vcc_wl>;
vqmmc-supply = <&vccio_wl>;
status = "okay";
};

For UHS switch I've added vqmmc-supply
vccio_sd: vccio-sd-regulator {
compatible = "regulator-fixed";
regulator-name = "vccio_sd";
regulator-min-microvolt = <3300000>;
regulator-max-microvolt = <3300000>;
vin-supply = <&vcc_io>;
};
And the slot detecting still 50MHz and timeout still effecting.
