- qcom,dec-ocmem-ab-ib : list of bus vectors(ab, ib pair) for ocmem
bandwidth request by different video decoder usecases.
- qcom,enc-ddr-ab-ib : list of bus vectors(ab,ib pair) for ddr bandwidth
request by different video encoder usecases.
- qcom,dec-ddr-ab-ib : list of bus vectors(ab, ib pair) for ddr bandwidth
request by different video decoder usecases.
- qcom,buffer-type-tz-usage-table : a key-value pair, mapping a buffer type
(enum hal_buffer) to its corresponding TZ usage. The TZ usages are defined
as "enum cp_mem_usage" in include/linux/msm_ion.h
- qcom,has-ocmem: indicate the target has ocmem if this property exists
- qcom,vidc-iommu-domains: node containing individual domain nodes, each with:
- a unique domain name for the domain node (e.g vidc,domain-ns)
- qcom,vidc-domain-phandle: phandle for the domain as defined in
<target>-iommu-domains.dtsi (e.g msm8974-v1-iommu-domains.dtsi)
- qcom,vidc-partition-buffer-types: bitmap of buffer types that can
be mapped into each IOMMU domain partition. There must be exactly
one buffer bitmap per partition in the domain, with order of the
bitmaps to be the same as the order of the respective partitions.
- Buffer types are defined as the following:
input = 0x1
output = 0x2
output2 = 0x4
extradata input = 0x8
extradata output = 0x10
extradata output2 = 0x20
internal scratch = 0x40
internal scratch1 = 0x80
internal scratch2 = 0x100
internal persist = 0x200
internal persist1 = 0x400
internal cmd queue = 0x800
