ba1dc7f273 Char / Misc driver changes for 5.15-rc1
Here is the big set of char/misc driver changes for 5.15-rc1.
 
 Lots of different driver subsystems are being updated in here, notably:
 	- mhi subsystem update
 	- fpga subsystem update
 	- coresight/hwtracing subsystem update
 	- interconnect subsystem update
 	- nvmem subsystem update
 	- parport drivers update
 	- phy subsystem update
 	- soundwire subsystem update
 and there are some other char/misc drivers being updated as well:
 	- binder driver additions
 	- new misc drivers
 	- lkdtm driver updates
 	- mei driver updates
 	- sram driver updates
 	- other minor driver updates.
 
 Note, there are no habanna labs driver updates in this pull request,
 that will probably come later before -rc1 is out in a different request.
 
 All of these have been in linux-next for a while with no reported
 problems.

27cfdadd68 bus: fsl-mc: extend fsl_mc_get_endpoint() to pass interface ID
In case of a switch DPAA2 object, the interface ID is also needed when
querying for the object endpoint. Extend fsl_mc_get_endpoint() so that
users can also pass the interface ID that are interested in.

8990f96a01 bus: fsl-mc: fix mmio base address for child DPRCs
Some versions of the MC firmware wrongly report 0 for register base
address of the DPMCP associated with child DPRC objects thus rendering
them unusable. This is particularly troublesome in ACPI boot scenarios
where the legacy way of extracting this base address from the device
tree does not apply.
Given that DPMCPs share the same base address, workaround this by using
the base address extracted from the root DPRC container.

8567494ceb bus: fsl-mc: rescan devices if endpoint not found
If the endpoint of a device is not yet probed on the bus, force
a rescan of the devices and retry to get a reference to the
endpoint device. If the device is still not found then we assume
it's in a different isolation context (container/DPRC) thus
unavailable and return a permission error.

8c97a4fc1b bus: fsl-mc: pause the MC firmware before IOMMU setup
Add a bus notifier to pause the MC firmware as soon as its device
gets discovered. This is needed as the firmware is live thus, as soon
as the SMMU gets probed and enabled, it will crash the firmware due to
SMMU context faults. The firmware will be resumed at probe time, after
the required IOMMU setup was completed.

e229b429bb Char/Misc driver patches for 5.12-rc1
Here is the large set of char/misc/whatever driver subsystem updates for
 5.12-rc1.  Over time it seems like this tree is collecting more and more
 tiny driver subsystems in one place, making it easier for those
 maintainers, which is why this is getting larger.
 
 Included in here are:
 	- coresight driver updates
 	- habannalabs driver updates
 	- virtual acrn driver addition (proper acks from the x86
 	  maintainers)
 	- broadcom misc driver addition
 	- speakup driver updates
 	- soundwire driver updates
 	- fpga driver updates
 	- amba driver updates
 	- mei driver updates
 	- vfio driver updates
 	- greybus driver updates
 	- nvmeem driver updates
 	- phy driver updates
 	- mhi driver updates
 	- interconnect driver udpates
 	- fsl-mc bus driver updates
 	- random driver fix
 	- some small misc driver updates (rtsx, pvpanic, etc.)
 
 All of these have been in linux-next for a while, with the only reported
 issue being a merge conflict in include/linux/mod_devicetable.h that you
 will hit in your tree due to the dfl_device_id addition from the fpga
 subsystem in here.  The resolution should be simple.

2cf1e703f0 bus: fsl-mc: add fsl-mc userspace support
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.
