Dasharo EC port for NovaCustom MTL dGPU models

[mkopec]

The problem you're addressing (if any)

The dGPU boards are different to iGPU models and require a separate EC port.

Describe the solution you'd like

Develop a port of Dasharo EC for NovaCustom Meteor Lake models with discrete graphics.

• Add GPIO configuration
• Add dGPU config
• Verify USB-PD config
• potentially also handle display mux override

Where is the value to a user, and who might that user be?
