This patch series 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. Changes in v2: - Fixed dt-bindings issues, see https://patchwork.ozlabs.org/patch/1260819/.
