Subject: dt-bindings: display: meson-vpu: Add the CVBS DAC properties
|
|
|
|
The CVBS DAC converts the digital video signal to the (analog) composite
|
|
video baseband signal (CVBS). This DAC is part of the HHI registers.
|
|
Add the phy and phy-names property to describe the relation between the
|
|
VPU (which outputs the digital signal) and the CVBS DAC.
|
|
