Subject: [Intel-gfx] [PATCH v2 2/8] drm/i915: Use intel_de_write_fw() for skl+ scaler registers
Date: Wed, 12 Feb 2020 18:17:32 +0200	[thread overview]
Message-ID: <20200212161738.28141-3-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <20200212161738.28141-1-ville.syrjala@linux.intel.com>

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

We have to write quite a few registers when programming the
pipe scaler. Let's use intel_de_write_fw() for these to reduce
the lockdep overhead a bit. All plane registers (including plane
scaler) already do this.

We already had a few accidental intel_de_write_fw() in there.
