Subject: [PATCH 18/26] drm/i915/slpc: Add slpc support for max/min freq
Date: Tue,  8 Mar 2016 16:34:21 -0800	[thread overview]
Message-ID: <1457483669-155235-19-git-send-email-tom.orourke@intel.com> (raw)
In-Reply-To: <1457483669-155235-1-git-send-email-tom.orourke@intel.com>

From: Tom O'Rourke <Tom.O'Rourke@intel.com>

Update sysfs and debugfs functions to set SLPC
parameters when setting max/min frequency.

v2: Update for SLPC 2015.2.4 (params for both slice and unslice)
    Replace HAS_SLPC with intel_slpc_active() (Paulo)
