This series presents ongoing work with the scaler partition algorithm. It is based upon the previous partition algorithm improvements submission [0] This series has been pushed to a tag [1] for convenience in testing. Patches 1-3, provide fixes and additions to the register definitions needed for controlling the phases of the UDS. Patches 4 and 5 rework the partition data configuration storage, opening the path for Patch 6 to implement a new entity operation API. This new '.partition' operation gives each entity an opportunity to adapt the partition data based on its configuration. A new helper function "vsp1_pipeline_propagate_partition()" is provided by the vsp1_pipe to walk the pipeline in reverse, with each entity having the opportunity to define it's input requirements to the predecessors. Partition data is stored somewhat inefficiently in this series, whilst the process is established and can be considered for improvement later. Patch 7 begins the implementation of calculating the phase values in the UDS, and applying them in the VI6_UDS_HPHASE register appropriately. Phase calculations have been established from the partition algorithm pseudo code provided by renesas, although the 'end phase' is always set as 0 in this code, it is yet to be determined if this has an effect. Finally Patch 8, begins to allow the UDS entity to perform extra overlap at the partition borders to provide the filters with the required data to generate clean transitions from one partition to the next.
