Okay.

Otherwise looks good.

It's three different hardware blocks (WiFi, BT and FM-radio) with shared
RF-hardware and an ARM core for control logic.

There seems to be some control commands going towards the BT part that
controls coexistence properties of the RF-hardware, but other than that
I see it as logically separate blocks.


So I think it's fine to model this as separate pieces in DT.

Are BT/FM functions completely separate? If so, separate bindings are 
okay. If not, then we need to describe the full chip.

+Qualcomm WCN36xx WiFi Binding
+
+This binding describes the Qualcomm WCN36xx WiFi hardware. The hardware block
+is part of the Qualcomm WCNSS core, a WiFi/BT/FM combo chip, found in a variety
+of Qualcomm platforms.
+
+- compatible:
+   Usage: required
+   Value type: 
+   Definition: must be one of:
+   "qcom,wcn3620-wlan",
+   "qcom,wcn3660-wlan",
+   "qcom,wcn3680-wlan"
+
+- qcom,smd-channel:
+   Usage: required
+   Value type: 
+   Definition: standard SMD property specifying the SMD channel used for
+   communication with the WiFi firmware
+
+- interrupts:
+   Usage: required
+   Value type: 
+   Definition: should specify the two IRQs for tx and rx respectively
+
+- qcom,wcnss-mmio:
+   Usage: required
+   Value type: 
+   Definition: should specify base address and size of the WiFi related
+   registers of WCNSS
+
+- qcom,state:
+   Usage: required
