Subject: [Intel-gfx] [PATCH v2 08/50] drm/i915/xelpd: Handle LPSP for XE_LPD
Date: Thu, 25 Mar 2021 11:06:38 -0700	[thread overview]
Message-ID: <20210325180720.401410-9-matthew.d.roper@intel.com> (raw)
In-Reply-To: <20210325180720.401410-1-matthew.d.roper@intel.com>

From: Uma Shankar <uma.shankar@intel.com>

Enable LPSP for XE_LPD and get the proper power well
enable check in place. For XE_LPD it is PW2 which
need to check for LPSP.

v2:
 - Move the XE_LPD check outside of the switch.  (Lucas)
