- compatible:
Usage: required
Value type: <stringlist>
Definition: Value should contain one of:
- "qcom,msm8916-venus"
- "qcom,msm8996-venus"
- "qcom,sdm845-venus"
- reg:
Usage: required
Value type: <prop-encoded-array>
Definition: Register base address and length of the register map.
- interrupts:
Usage: required
Value type: <prop-encoded-array>
Definition: Should contain interrupt line number.
- clocks:
Usage: required
Value type: <prop-encoded-array>
Definition: A List of phandle and clock specifier pairs as listed
in clock-names property.
- clock-names:
Usage: required for msm8916
Value type: <stringlist>
Definition: Should contain the following entries:
- "core" Core video accelerator clock
- "iface" Video accelerator AHB clock
- "bus" Video accelerator AXI clock
- clock-names:
Usage: required for msm8996
Value type: <stringlist>
Definition: Should contain the following entries:
- "core" Core video accelerator clock
- "iface" Video accelerator AHB clock
- "bus" Video accelerator AXI clock
- "mbus" Video MAXI clock
- power-domains:
Usage: required
Value type: <prop-encoded-array>
Definition: A phandle and power domain specifier pairs to the
power domain which is responsible for collapsing
and restoring power to the peripheral.
- iommus:
Usage: required
Value type: <prop-encoded-array>
Definition: A list of phandle and IOMMU specifier pairs.
- memory-region:
Usage: required
Value type: <phandle>

memory region.
* Subnodes
The Venus video-codec node must contain two subnodes representing
video-decoder and video-encoder, and one optional firmware subnode.
Firmware subnode is needed when the platform does not have TrustZone.
Every of video-encoder or video-decoder subnode should have:
- compatible:
Usage: required
Value type: <stringlist>
Definition: Value should contain "venus-decoder" or "venus-encoder"
- clocks:
Usage: required for msm8996
Value type: <prop-encoded-array>
Definition: A List of phandle and clock specifier pairs as listed
in clock-names property.
- clock-names:
Usage: required for msm8996
Value type: <stringlist>
Definition: Should contain the following entries:
- "core" Subcore video accelerator clock
- power-domains:
Usage: required for msm8996
Value type: <prop-encoded-array>
Definition: A phandle and power domain specifier pairs to the
power domain which is responsible for collapsing
and restoring power to the subcore.
The firmware subnode must have:
- iommus:
Usage: required
Value type: <prop-encoded-array>
Definition: A list of phandle and IOMMU specifier pairs.
