[OpenWrt-Devel] How to initialize multiple phy radios

Hello,
So with some modifications to pci.c, hw.h and core.c I was able to get
the radio initialized! :)
pci.c: added QCA9887_DEVICE_ID, modified ath10k_pci_id_table and
ath10k_pci_supp_chips
core.c: Duplicated QCA988X entry in ath10k_hw_params_list and passed
0x4100016d as the ID ( left everything else the same )
hw.h: added definitions for QCA9887
I found "https://github.com/kvalo/ath10k-firmware/blob/master/QCA9887/firmware-5.bin_10.2.3.31.7-1"
on your github and replaced
/lib/firmware/ath10k/QCA988X/hw2.0/firmware-5.bin on my board.
hotplug.d then loaded QCA9887 firmware on next boot.
Of course my approach was very much a hack. If there is anything I can
contribute to creating a patch for ath10k, please let me know. I would
love to help!
