+  The ADL8113 is a 10MHz to 12GHz Low Noise Amplifier with integrated bypass
+  switches controlled by two GPIO pins (VA and VB). The device supports four
+  operation modes:
+    - Internal Amplifier: VA=0, VB=0 - Signal passes through the internal LNA
+    - Internal Bypass: VA=1, VB=1 - Signal bypasses through internal path
+    - External Bypass A: VA=0, VB=1 - Signal routes from RFIN to OUT_A and from IN_A to RFOUT
+    - External Bypass B: VA=1, VB=0 - Signal routes from RFIN to OUT_B and from IN_B to RFOUT

Could make things simpler to make a single property and use it as
a gpio array. I would call it switch-gpios.

Seems like we would also want some binding to describe what is
connected to each of the bypasses. Maybe io-channels that link
to other amplifier channels?
