HI
We use the RTL8723BS to enable the wifi feature.but the wifi do not work.the dts is followed.

why i use the insmod 8723bs.ko,it init the wifi driver,but not call the wifi probe function.
the mmc function is follow,in dts, i set mmc volt 3.3v,why the log show me 1.8v. is this caused the wifi can not work?
