* TSPP ( QTI Transport Stream Packet Processor )

Hardware driver for QTI TSIF 12seg wrapper core, which consists of a TSPP, a
BAM (Bus access manager, used for DMA) and two TSIF inputs.

The TSPP driver is responsible for:
 - TSPP/TSIF hardware configuration (using SPS driver to configure BAM hardware)
 - TSIF GPIO/Clocks configuration
 - Memory resource management
 - Handling TSIF/TSPP interrupts and BAM events
 - TSPP Power management

Required properties:
- compatible : Should be "qcom,msm_tspp"
- reg : Specifies the base physical addresses and sizes of TSIF, TSPP & BAM registers.
- reg-names : Specifies the register names of TSIF, TSPP & BAM base registers.
- interrupts : Specifies the interrupts associated with TSIF 12 seg core.
- interrupt-names: Specifies interrupt names for TSIF, TSPP & BAM interrupts.
- clock-names: Specifies the clock names used for interface & reference clocks.
- clocks: GCC_TSIF_AHB_CLK clock for interface clock & GCC_TSIF_REF_CLK clock for reference clock.
- qcom, msm_bus,name: Should be "tsif"
- qcom, msm_bus,num_cases: Depends on the use cases for bus scaling
- qcom, msm_bus,num_paths: The paths for source and destination ports
- qcom, msm_bus,vectors: Vectors for bus topology.
- pinctrl-names: Names for the TSIF mode configuration to specify which TSIF interface is active.
- qcom,smmu-s1-bypass : Boolean flag to bypass SMMU stage 1 translation.
- iommus : A list of phandle and IOMMU specifier pairs that describe the IOMMU master interfaces of the device.
