Hi Fabio,
In order NOT to permit the SDIO core controller to communicate in 3.3v
signal voltage, you need to define the vqmmc, voltage-ranges and vmmc
(see the example below).
I've tested this settings on 3.19 kernel and able to backport on 3.13.
wlan_en_reg: fixedregulator {
compatible = "regulator-fixed";
regulator-name = "wlan-en-regulator";
regulator-min-microvolt = <1800000>;
regulator-max-microvolt = <1800000>;
enable-active-high;
regulator-always-on;
};
reg_1p8v: 1p8v {
compatible = "regulator-fixed";
regulator-name = "1p8v";
regulator-min-microvolt = <1800000>;
regulator-max-microvolt = <1800000>;
};
/* WiLink8 WIFI module */
&usdhc2 {
status = "okay";
vmmc-supply = <&wlan_en_reg>;
vqmmc-supply = <®_1p8v>;
voltage-ranges = <1800 1800>;
};
Regards,
John
