Subject: [Intel-gfx] [PATCH 1/9] drm/i915/adl_s: Update PHY_MISC programming
Date: Wed, 27 Jan 2021 21:30:16 -0800	[thread overview]
Message-ID: <20210128053024.23540-2-aditya.swarup@intel.com> (raw)
In-Reply-To: <20210128053024.23540-1-aditya.swarup@intel.com>

From: Matt Roper <matthew.d.roper@intel.com>

ADL-S switches up which PHYs are considered a master to other PHYs;
PHY-C is no longer a master, but PHY-D is now.
