From 302fdb1688e33a33495d5e1f294da5b72a46e263 Mon Sep 17 00:00:00 2001 From: Christian Marangi Date: Tue, 4 Jun 2024 18:43:42 +0200 Subject: dt-bindings: hwmon: g76x: Add support for g761 Add support for g761 PWM Fan controller. This is an exact copy of g763 with the difference that it does also support an internal clock oscillator. With clocks property not defined, the internal clock oscillator is used.
