[USRP-users] device tree and GPIO pin for x4xx

[hiroki_iwata--- via USRP-users]

I am trying to understand the device tree and pin configuration of x4xx.

Especially, “RFDC_POWERD“ GPIO pin.

Now, I am searching the python 
script(mpm/python/usrp_mpm/periph_manager/x4xx.py) and I found that 
“RFDC_POWERED“ pin is GPIO pin. 

But, I cannot identify its corresponding device tree description. 

self._rfdc_powered = Gpio('RFDC_POWERED', Gpio.INPUT)

Where is the device tree definition for x4xx?  

BR,

Hiroki
