Subject: [PATCH 00/10] bus/fsl-mc: Extend mc-bus driver functionalities in preparation for mc-bus VFIO support

The vfio-mc bus driver needs some additional services to be exported by the
mc-bus driver like:
- a way to reset the DPRC container
- support for driver_override such taht the objects within a DPRC to be
bind to the VFIO driver
- functions to setup/tear dowan a DPRC
- functions for allocating the pool of interrupts. In case of VFIO the
interrupts are not configured at probe time, but later, when the userspace
configures the interrupts.

Bharat Bhushan (3):
  bus/fsl-mc: add support for 'driver_override' in the mc-bus
  bus/fsl-mc: Propagate driver_override for a child DPRC's children
  bus/fsl-mc: Add dprc-reset-container support

Diana Craciun (7):
  bus/fsl-mc: Do no longer export the total number of irqs outside dprc_scan_objects
  bus/fsl-mc: Add a new parameter to dprc_scan_objects function
  bus/fsl-mc: Set the QMAN/BMAN region flags
  bus/fsl-mc: Export a dprc scan function to be used by multiple
    entities
  bus/fsl-mc: Export a cleanup function for DPRC
  bus/fsl-mc: Add a container setup function
  bus/fsl-mc: Export IRQ pool handling functions to be used by VFIO
