Subject: [PATCH 06/12] drm/ast: Base support for AST2500
Date: Fri, 24 Feb 2017 09:53:51 +1100 [thread overview]
Message-ID: <20170223225357.9572-6-benh@kernel.crashing.org> (raw)
In-Reply-To: <20170223225357.9572-1-benh@kernel.crashing.org>
From: "Y.C. Chen" <yc_chen@aspeedtech•com>
Add detection and mode setting updates for AST2500 generation chip,
code originally from Aspeed and slightly reworked for coding style
mostly by Ben. This doesn't contain the BMC DRAM POST code which
is in a separate patch.
