From e9b95485c12c31e07dbb1694e794f18565144099 Mon Sep 17 00:00:00 2001 From: Jeremy Gebben Date: Mon, 4 Feb 2019 13:19:06 -0700 Subject: [PATCH] hwmon: (lm85) add support for LM96000 high frequencies The LM96000 expands the freqency field from 3 to 4 bits, to add more frequencies in the 22.5 to 30 kHz ranges.
