bcmdhd_wlan probing fails on imx8mqevk board

[ysandeepkumar07]

Hi all,

I am using imx8mqevk boardv3 development board Release - Linux 4.9.88_2.0.0_ga. wireless interface is missing. So on checking dmesg, I can see that bcmdhd_wlan probing fails. see below log.

[    2.448885] bcmdhd_wlan@0 supply wlreg_on not found, using dummy regulator
[    2.449100] bcmdhd_wlan: probe of bcmdhd_wlan@0 failed with error -1

So its a pre-build, hence wifi/bt  module should be working directly, what may be the solution to start wifi and bluetooth both.

Actually we are planning to use Release - Linux 4.9.88_2.0.0_ga only for our custom board development. So may I know, how can we support QCA6174 for this release. Or may I know when will NXP officially releases 4.9.88_2.0.0_ga with full working stack.
