Can't make the driver work on Linux 4.9.170

[ruslanbyku]

I've got a custom board with a 4.9.170 kernel on Linux on aarch64 (Allwinner). I compiled the driver successfully, it is loaded on boot and dmesg shows me that the driver seems to be in the working state, the firmware has been loaded fine and the wlan interface is in the UP state. But every time I try to scan the devices I see in syslog that the driver loads the firmware again and with the success status. SDIO pins seems to be in the working state. Here is the log:

# cat /proc/net/rtl8723ds/log_level

  _DRV_WARNING_ = 3 = 3
  _DRV_INFO_ = 4 = 4

  _DRV_MAX_ = 6 = 6

This is a snippet of the SDIO parameters in the device tree file that are used (they work for other wifi modules such as rtl8822bs):

sdc1: sdmmc@04021000 {
		pinctrl-0 = <&sdc1_pins_a>;
		bus-width = <4>;
		no-mmc;
		no-sd;
		cap-sd-highspeed;
		/*sd-uhs-sdr12*/
		/*sd-uhs-sdr25*/
		sd-uhs-sdr50;
		sd-uhs-ddr50;
		sd-uhs-sdr104;
		/*sunxi-power-save-mode;*/
		sunxi-dis-signal-vol-sw;
		/*sdio-used-1v8;*/
		cap-sdio-irq;
		keep-power-in-suspend;
		ignore-pm-notify;
		max-frequency = <150000000>;
		ctl-spec-caps = <0x8>;
		status = "okay";
};

As I said earlier, every time I try to scan the devices I get:

What is interesting I have the exact same board (the same OS, kernel version, device tree and hardware) except for the wifi module rtl8822bs and it works out nice (with a respective driver, of course), so I am not sure my rootfs is configured wrong.
I also managed to compile Android OS on the Allwinner board (which used to be Linux) and compiled the 8723ds driver for it but wifi still does not work, the log is the same as for the LInux. So I believe it is not the kernel distinction that is to blame as well.

This issue might not be in the current driver software, but how can I troubleshoot it further?

Thanks in advance.
