Subject: [Intel-gfx] [PATCH v2 12/22] drm/i915/rkl: Check proper SDEISR bits for TC1 and TC2 outputs
Date: Mon,  4 May 2020 15:52:17 -0700	[thread overview]
Message-ID: <20200504225227.464666-13-matthew.d.roper@intel.com> (raw)
In-Reply-To: <20200504225227.464666-1-matthew.d.roper@intel.com>

When Rocket Lake is paired with a TGP PCH, the last two outputs utilize
the TC1 and TC2 hpd pins, even though these are combo outputs.
