+title: Bindings for Ingenic JZ4780 HDMI Transmitter
+maintainers:
- H. Nikolaus Schaller hns@goldelico.com
+description: |
- The HDMI Transmitter in the Ingenic JZ4780 is a Synopsys
DesignWare HDMI 1.4
- TX controller IP with accompanying PHY IP.
My dmesg disagrees: dw-hdmi-ingenic 10180000.hdmi: Detected HDMI TX controller v1.31a with HDCP (DWC HDMI 3D TX PHY)
Or am I comparing apples to oranges?
+allOf:
- $ref: bridge/synopsys,dw-hdmi.yaml#
+properties:
- compatible:
- const: ingenic,jz4780-dw-hdmi
- reg-io-width:
- const: 4
- clocks:
- maxItems: 2
- hdmi-5v-supply:
- description: Optional regulator to provide +5V at the connector
- ddc-i2c-bus:
- description: An I2C interface if the internal DDC I2C driver is
not to be used
This property is used within (drivers/gpu/drm/bridge/synopsys/dw-hdmi.c); I think it would make sense to move it to bridge/synopsys,dw-hdmi.yaml.
Cheers, -Paul
