From: Diana Craciun <diana.craciun@oss.nxp.com>
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 - driver_override support - functions to setup/tear down a DPRC - functions for allocating the pool of interrupts. In case of VFIO the interrupts are not configured at probe time, but later by userspace request
v2 -> v3 - Add a new version for dprc_get_obj_region - Export the cacheability bus specific bits defines
v1 -> v2 - Remove driver_override propagation through various functions - Cache the DPRC API version
The patches are related with "vfio/fsl-mc: VFIO support for FSL-MC devices" patches, but the series were split because they are targeting different subsystems. However, the mc-bus patches may suffer changes when addressing the VFIO review comments.
Bharat Bhushan (3): bus/fsl-mc: add support for 'driver_override' in the mc-bus bus/fsl-mc: Add dprc-reset-container support bus/fsl-mc: Extend ICID size from 16bit to 32bit
Diana Craciun (10): 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: Cache the DPRC API version 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: Do not rely on caller to provide non NULL mc_io bus/fsl-mc: Export IRQ pool handling functions to be used by VFIO bus/fsl-mc: Add a new version for dprc_get_obj_region command
