From 6495567981be6f91eccb48e058ca88dd7acad181 Mon Sep 17 00:00:00 2001 From: Sean Nyekjaer Date: Thu, 14 Nov 2024 10:14:49 +0100 Subject: [PATCH] dt-bindings: can: tcan4x5x: Document the ti,nwkrq-voltage-vio option The nWKRQ pin supports an output voltage of either the internal reference voltage (3.6V) or the reference voltage of the digital interface 0-6V (VIO). Add the devicetree option ti,nwkrq-voltage-vio to set it to VIO. If this property is omitted the reset default, the internal reference voltage, is used.
