[PATCH v3 0/4] drm: Add support for IPK DSI Host Driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
