Subject: [PATCH v2 08/18] smiapp-pll: Don't validate OP clocks if there are none
Date: Thu,  2 Oct 2014 11:45:58 +0300	[thread overview]
Message-ID: <1412239568-8524-9-git-send-email-sakari.ailus@iki.fi> (raw)
In-Reply-To: <1412239568-8524-1-git-send-email-sakari.ailus@iki.fi>

From: Sakari Ailus <sakari.ailus@linux.intel.com>

For profile 0 sensors (which have no OP clocks), the OP limits are in fact
VT limits. Do not verify them again.
