Subject: [Intel-gfx] [PATCH 01/37] drm/i915/rkl: Add DPLL4 support
Date: Wed, 20 May 2020 17:37:27 -0700	[thread overview]
Message-ID: <20200521003803.18936-2-lucas.demarchi@intel.com> (raw)
In-Reply-To: <20200521003803.18936-1-lucas.demarchi@intel.com>

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

Rocket Lake has a third DPLL (called 'DPLL4') that must be used to
enable a third display.  Unlike EHL's variant of DPLL4, the RKL variant
behaves the same as DPLL0/1.  And despite its name, the DPLL4 registers
are offset as if it were DPLL2, so no extra offset handling is needed
either.
