Subject: [PATCH 3/6] drm/aspeed: Add AST2600 support
Date: Tue, 28 Sep 2021 10:57:00 +0800	[thread overview]
Message-ID: <20210928025703.10909-4-tommy_huang@aspeedtech.com> (raw)
In-Reply-To: <20210928025703.10909-1-tommy_huang@aspeedtech.com>

From: Joel Stanley <joel@jms.id.au>

The values for the threshold and scan line size come from the ASPEED
SDK.

The DAC register is SCUC0 in the AST2600 datasheet. It has the same
layout as the previous generations.
