From: Leonardo Costa <[email protected]> Add a device tree overlay for the VGA output available on the Apalis Evaluation Board, which is driven from a parallel RGB interface passing through a non-programmable video DAC to a VGA connector, without VESA DDC I2C signals.
The overlay is also combined with the various Apalis Evaluation Board device trees to provide ready-to-use DTBs.
