  1. Synopsys DesignWare HDMI TX Encoder
  2. ===================================
  3. This document defines device tree properties for the Synopsys DesignWare HDMI
  4. TX Encoder (DWC HDMI TX). It doesn't constitue a device tree binding
  5. specification by itself but is meant to be referenced by platform-specific
  6. device tree bindings.
  7. When referenced from platform device tree bindings the properties defined in
  8. this document are defined as follows. The platform device tree bindings are
  9. responsible for defining whether each property is required or optional.
  10. - reg: Memory mapped base address and length of the DWC HDMI TX registers.
  11. - reg-io-width: Width of the registers specified by the reg property. The
  12. value is expressed in bytes and must be equal to 1 or 4 if specified. The
  13. register width defaults to 1 if the property is not present.
  14. - interrupts: Reference to the DWC HDMI TX interrupt.
  15. - clocks: References to all the clocks specified in the clock-names property
  16. as specified in Documentation/devicetree/bindings/clock/clock-bindings.txt.
  17. - clock-names: The DWC HDMI TX uses the following clocks.
  18. - "iahb" is the bus clock for either AHB and APB (mandatory).
  19. - "isfr" is the internal register configuration clock (mandatory).
  20. - "cec" is the HDMI CEC controller main clock (optional).
  21. - ports: The connectivity of the DWC HDMI TX with the rest of the system is
  22. expressed in using ports as specified in the device graph bindings defined
  23. in Documentation/devicetree/bindings/graph.txt. The numbering of the ports
  24. is platform-specific.
