Pull char/misc and other driver subsystem updates from Greg KH:
 "Here is the big set of char/misc and other driver subsystem updates
  for 6.10-rc1. Nothing major here, just lots of new drivers and updates
  for apis and new hardware types. Included in here are:

   - big IIO driver updates with more devices and drivers added

   - fpga driver updates

   - hyper-v driver updates

   - uio_pruss driver removal, no one uses it, other drivers control the
     same hardware now

   - binder minor updates

   - mhi driver updates

   - excon driver updates

   - counter driver updates

   - accessability driver updates

   - coresight driver updates

   - other hwtracing driver updates

   - nvmem driver updates

   - slimbus driver updates

   - spmi driver updates

   - other smaller misc and char driver updates

  All of these have been in linux-next for a while with no reported
  issues"

mfd: intel-m10-bmc: Change staging size to a variable

2024-05-10T14:39:16+00:00

The secure update driver does a sanity-check of the image size in
comparison to the size of the staging area in FLASH. Instead of
hard-wiring M10BMC_STAGING_SIZE, move the staging size to the
m10bmc_csr_map structure to make the size assignment more flexible.

fpga: dfl-pci: add PCI subdevice ID for Intel D5005 card

2024-04-26T04:14:28+00:00

Add PCI subdevice ID for the Intel D5005 Stratix 10 FPGA card as
used with the Open FPGA Stack (OFS) FPGA Interface Manager (FIM).

Unlike the Intel D5005 PAC FIM which exposed a separate PCI device ID,
the OFS FIM reuses the same device ID for all DFL-based FPGA cards
and differentiates on the subdevice ID. The subdevice ID values were
chosen as the numeric part of the FPGA card names in hexadecimal.

fpga: region: add owner module and take its refcount

2024-04-23T07:37:20+00:00

The current implementation of the fpga region assumes that the low-level
module registers a driver for the parent device and uses its owner pointer
to take the module's refcount. This approach is problematic since it can
lead to a null pointer dereference while attempting to get the region
during programming if the parent device does not have a driver.

To address this problem, add a module owner pointer to the fpga_region
struct and use it to take the module's refcount. Modify the functions for
registering a region to take an additional owner module parameter and
rename them to avoid conflicts. Use the old function names for helper
macros that automatically set the module that registers the region as the
owner. This ensures compatibility with existing low-level control modules
and reduces the chances of registering a region without setting the owner.

Also, update the documentation to keep it consistent with the new interface
for registering an fpga region.

fpga: tests: use KUnit devices instead of platform devices

2024-04-09T04:13:15+00:00

KUnit now provides helper functions to create fake devices, so use them
instead of relying on platform devices.

Other changes: remove an unnecessary white space in the fpga region suite.
