[PATCH v2 2/2] dt-bindings: can: tcan4x5x: Document the ti,nwkrq-voltage-sel option
From: Sean Nyekjaer
Date: Mon Nov 11 2024 - 03:56:02 EST
nWKRQ supports an output voltage of either the internal reference voltage
(3.6V) or the reference voltage of the digital interface 0 - 6V.
Add the devicetree option ti,nwkrq-voltage-sel to be able to select
between them.
