13  This document defines device tree properties for the Synopsys DesignWare HDMI
14  TX controller (DWC HDMI TX) IP core. It doesn't constitute a full device tree
15  binding specification by itself but is meant to be referenced by device tree
16  bindings for the platform-specific integrations of the DWC HDMI TX.
17
18  When referenced from platform device tree bindings the properties defined in
19  this document are defined as follows. The platform device tree bindings are
20  responsible for defining whether each property is required or optional.

51    description:
52      The HDMI DDC bus can be connected to either a system I2C master or the
53      functionally-reduced I2C master contained in the DWC HDMI. When connected
54      to a system I2C master this property contains a phandle to that I2C
55      master controller.
56
57      This property is deprecated, the system I2C master controller should
58      be referenced through the ddc-i2c-bus property of the HDMI connector
59      node.
