[PATCH V2 1/2] dt-bindings: display: xlnx: Add DSI 2.0 Tx subsystem documentation

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

 



This patch adds dt binding for Xilinx DSI-TX subsystem.

The Xilinx MIPI DSI (Display serial interface) Transmitter Subsystem
implements the Mobile Industry Processor Interface (MIPI) based display
interface. It supports the interface with the programmable logic (FPGA).
