The Freescale arm64 device tree updates for 4.8:

Browse Source 
- Update address-cells and reg properties of cpu nodes, considering
    MPIDR_EL1[63:32] bits are not used for CPUs identification on ls1043a
    and ls2080a
  - Adds the cache nodes and next-level-cache property for ls1043a and
    ls2080a to get cacheinfo work on these platforms
  - Add dma-coherent for ls1043a PCI nodes to utilize the hardware
    capability on data coherency
  - Add dis_rxdet_inp3_quirk property for USB3 device to disable rx
    detection in P3 PHY mode

of the data transferred from/to the IP block. This can avoid the software
