Good question, for vidc-msm8916 it is one power-domain, for vidc-msm8996 the power domains should be 3. Here the problem is that the genpd doesn't permit more than one power-domain per device. > >> + >> +- clocks: >> + Usage: required >> + Value type: <prop-encoded-array> >> + Definition: List of phandle and clock specifier pairs as listed >> + in clock-names property >> +- clock-names: >> + Usage: required >> + Value type: <stringlist> >> + Definition: Should contain the following entries >> + - "core" Core video accelerator clock >> + - "iface" Video accelerator AHB clock >> + - "bus" Video accelerator AXI clock >> +- rproc: >> + Usage: required >> + Value type: <prop-encoded-array> >> + Definition: A phandle to remote processor responsible for >> + firmware loading >> + >> +- iommus: >> + Usage: required >> + Value type: <prop-encoded-array> >> + Definition: A list of phandle and IOMMU specifier pairs >> + >> +* An Example >> + qcom,vidc@1d00000 { > > node names should be generic: video-codec@ correct, will update it in next version. -- regards, Stan ^ permalink raw reply [flat|nested] 3+ messages in thread
