1. Add functionality in qdutils to get the DP test config from the sysfs node. 2. Add support to generate ColorRamp, ColorSquare and Black and White vertical line test pattern for 18/24/30 bpp DP display 3. Create layer stack with test layer and ignore all layers from the SF framework. 4. Generate the pattern with 18/24/30 bpp based on pattern type and bpp read from sysfs node and send it to DP interface. 5. Add support to calculate CRC to validate the color pattern.
