From 55c63aaa6952c819e772e9c2d4a7602c062f012c Mon Sep 17 00:00:00 2001 From: Jiri Pirko Date: Tue, 22 Nov 2016 11:24:12 +0100 Subject: [PATCH] mlxsw: reg: Add Management Fan Speed Limit register The MFSL register is used to configure the fan speed event / interrupt notification mechanism. Fan speed threshold are defined for both under-speed and over-speed. Signed-off-by: Jiri Pirko Reviewed-by: Ido Schimmel Signed-off-by: David S.
