Controlling a PA with nRF52840 via Zephyr

[CktDesigner]

I'm attempting to control a PA attached to an nRF52840 in a way similar to Case ID: 212504

But I'm also using Zephyr...   

Are there equivalent calls available via the Zephyr Bluetooth driver to register the PA control pins, etc.?

Thanks!

After some additional searching, I found that support for the PA in Zephyr is handled via DeviceTree.

Adding the appropriate entry into my custom board .dts and assigning the pins there fixed things!
