Hi All,
We are trying to bring up Qualcomm's QCA6134 SDIO WiFi chip in to i.mx6 custom board. Log messages shows it is detected as a mmc sdio card. But while loading the ath6kl drivers, it shows some error.
The device tree and other software details:
&usdhc2 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_usdhc2_2>;
bus-width = <4>;
no-1-8-v;
keep-power-in-suspend;
enable-sdio-wakeup;
non-removable;
status = "okay";
};
Two gpios - WLAN_PWD_L and BT_PWD_L (These two gpios configured based on the datasheet)
Freescale BSP 3.10.17,
Wireless Backport drivers v4.1.1-1-0-g8286954,
i.MX6 Solo Processor
The below messages got while power up the board and attached file have the logs, which got while loading the ath6kl backport drivers.

Is the message " mmc0: no vqmmc regulator found mmc0: no vmmc regulator found " have any issue? or the device tree configurations need any modification??
The ios file contetns:
root@imx6qdlsolo:/sys/kernel/debug/mmc0# cat ios
clock: 50000000 Hz
actual clock: 49500000 Hz
vdd: 17 (2.9 ~ 3.0 V)
bus mode: 2 (push-pull)
chip select: 0 (don't care)
power mode: 2 (on)
bus width: 2 (4 bits)
timing spec: 2 (sd high-speed)
signal voltage: 0 (3.30 V)
root@imx6qdlsolo:/sys/kernel/debug/mmc0#
Every help is very appreciated
