These are for the wireless chips that come built in with various
Atheros/QCA SoCs. dts wise, the difference between pcie and the wmac is
AHB > PCIE > WIFI
AHB > WIFI
These will be used to replace the platform_device code with OF in the

I assume you're referring to

They do. An example being the ar71xx driver which has
- qca,ar9130-eth # Atheros AR9130
- qca,ar9330-eth # Atheros AR9330
- qca,ar9340-eth # Atheros AR9340
- qca,qca9530-eth # Qualcomm Atheros QCA9530
- qca,qca9550-eth # Qualcomm Atheros QCA9550
- qca,qca9560-eth # Qualcomm Atheros QCA9560
I was advised earlier to change it to qcom instead of qca. Qualcomm
itself uses the qcom, prefix for its maintained drivers while the non
Qualcomm maintained stuff uses qca.
