You are right. Now I found the correct chip ID by enabling debug with 
Broadcom kernel module 'modprobe brcmfmac debug=0x3ffff6'

The module is Ampak AP6212A with Broadcom 43430 rev=1 inside it.

brcmfmac: brcmf_chip_recognition found AXI chip: BCM43430, rev=1
brcmfmac: brcmf_ops_sdio_probe sdio vendor ID: 0x02d0
brcmfmac: brcmf_ops_sdio_probe sdio device ID: 0xa9a6

IPv6: ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready

This information mostly match with https://wikidevi.com/wiki/AMPAK, except 
module is actually AP6212A. Some of the modules may not have 'A' printed on 
them. However the ones that identify as rev=1 is a  AP6212A.

FYI: there were two things that confused me
	- bcm4329-fmac also works.
	- I couldn't configure it to join WiFi network with password.

With change I will send a v4. Here is the propssed diff to v3.

arch/arm64/boot/dts/allwinner/sun50i-h5-nanopi-neo-plus2.dts

        /*
-        * WiFi driver support could be incomplete,
-        * wlan0 is able to see Base Stations, however not able to join.
+        * AMPAK AP6212A WiFi module with BCM43430, rev=1 inside
+        * sdio vendor ID: 0x02d0, sdio device ID: 0xa9a6
         */
	brcmf: wifi@1 {
		reg = <1>;
-               compatible = "brcm,bcm4329-fmac";
+               compatible = "brcm,bcm43430-fmac";
	}; 

I think now nanopi-neo-plus2.dts, v4, is in a good shape to merge.

thanks for the feedback and review.
