Tool/software: Linux
We use WL1837MODCOM8I eval board to test WL1837MOD wifi module with TI linux 4.4.41 version.
We include wl18xx components and mmc1 in dts.
After every reboot we see the following error
[ 2.249440] sdio_enable_4bit_bus MMC_TYPE_SDIO
[ 2.271245]
[ 2.278686] mmc1: error -110 whilst initialising SDIO card

Does anyone know what can the problem be?
The configuration is bellow:
&mmc2 {
status = "okay";
bus-width = <0x4>;
cap-power-off-card;
pinctrl-names = "default";
pinctrl-0 = <&mmc2_pins>;
vmmc-supply = <&wl12xx_vmmc>;
ti,non-removable;
keep-power-in-suspend;
enable-sdio-wakeup;
ti,needs-special-hs-handling;
#address-cells = <1>;
#size-cells = <0>;
wlcore: wlcore@2 {
compatible = "ti,wl1837";
reg = <2>;
interrupt-parent = <&gpio0>;
interrupts = <31 IRQ_TYPE_LEVEL_HIGH>; /* gpio 31 */
ref-clock-frequency = <38400000>;
};
};
