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