Adds support for the display subsystem in the Synopsys DesignWare IPK devices. The display pipeline is limited and does not have access to memory, the validation is done using a VPG (Video Pattern Generator), as DPI stimulus for the DW MIPI DSI Host. A Synopsys DesignWare MIPI DSI Host v1.40 is used in the IPK device, that so far, is fully compatible with the driver dw-mipi-dsi. To activate the VPG use the sysfs pattern variable, assigning values from 0 (shutdown) to 4. The usage of the VPG and the Synopsys DesignWare MIPI DSI Host internal video generator is mutually exclusive. The submission of this driver aims to be used as a work base for the submission of enhancements over the Synopsys DesignWare MIPI DSI Host.
