2022-11-17genirq: Get rid of GENERIC_MSI_IRQ_DOMAINThomas Gleixner
Adjust to reality and remove another layer of pointless Kconfig indirection. CONFIG_GENERIC_MSI_IRQ is good enough to serve all purposes.

2021-01-27bus: fsl-mc: add fsl-mc userspace supportIoana Ciornei
Adding userspace support for the MC (Management Complex) means exporting an ioctl capable device file representing the root resource container. This new functionality in the fsl-mc bus driver intends to provide userspace applications an interface to interact with the MC firmware. Commands that are composed in userspace are sent to the MC firmware through the FSL_MC_SEND_MC_COMMAND ioctl. By default the implicit MC I/O portal is used for this operation, but if the implicit one is busy, a dynamic portal is allocated and then freed upon execution. The command received through the ioctl interface is checked against a known whitelist of accepted MC commands. Commands that attempt a change in hardware configuration will need CAP_NET_ADMIN, while commands used in debugging do not need it.

2018-02-22staging: fsl-mc: Move core bus out of stagingBogdan Purcareata
Move the source files out of staging into their final locations: -mc.h include file in drivers/staging/fsl-mc/include go to include/linux/fsl -source files in drivers/staging/fsl-mc/bus go to drivers/bus/fsl-mc -overview.rst, providing an overview of DPAA2, goes to Documentation/networking/dpaa2/overview.rst Update or delete other remaining staging files -- Makefile, Kconfig, TODO. Update dpaa2_eth and dpio staging drivers. Add integration bits for the documentation build system.
