Merge tag 'soc-fsl-next-v5.1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/leo/linux into arm/drivers

NXP/FSL SoC driver updates for v5.1

DPIO driver
- Clean up the remove path in the dpio driver so that successive
  bind/unbind commands behave properly
- Add the ability to automatically create a device link between a
  consumer device on the fsl-mc bus and a supplier one
- Add prefetch to dpio dequeue to improve performance
- Update the type of dpio APIs to align with buffer pool id register
  field

guts driver
- Prevent allocation failure by reuse the machine type data from device
  tree directly

* tag 'soc-fsl-next-v5.1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/leo/linux:
  soc: fsl: guts: reuse machine name from device tree
  soc: fsl: dpio: Change bpid type to u16
  soc: fsl: dpio: Add prefetch instruction
  bus: fsl-mc: automatically add a device_link on fsl_mc_[portal,object]_allocate
  soc: fsl: dpio: add a device_link at dpaa2_io_service_register
  soc: fsl: dpio: store a backpointer to the device backing the dpaa2_io
  soc: fsl: dpio: keep a per dpio device MC portal
  soc: fsl: dpio: perform DPIO Reset on Probe
  soc: fsl: dpio: use a cpumask to identify which cpus are unused
  soc: fsl: dpio: cleanup the cpu array on dpaa2_io_down
