[PATCH 3/6] drm/aspeed: Add AST2600 support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Joel Stanley <joel@xxxxxxxxx>

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.
