Right now, ath10k wireless driver has support for PCI based wlan devices. There is a plan to extend ath10k driver to support wifi devices which are connected over AHB as well (enumeration will happen via device tree node). For AHB based devices (ie, ipq4019), all wifi properties are supplied via device tree (including irq, reg addr, cal data,etc).
