Linus Torvalds 44aeec836d Char/Misc and other driver subsystem updates for 6.5-rc1
Here is the big set of char/misc and other driver subsystem updates for
 6.5-rc1.
 
 Lots of different, tiny, stuff in here, from a range of smaller driver
 subsystems, including pulls from some substems directly:
   - IIO driver updates and additions
   - W1 driver updates and fixes (and a new maintainer!)
   - FPGA driver updates and fixes
   - Counter driver updates
   - Extcon driver updates
   - Interconnect driver updates
   - Coresight driver updates

 on top of that, lots of small driver updates as patches, including:
   - static const updates for class structures
   - nvmem driver updates
   - pcmcia driver fix
   - lots of other small driver updates and fixes
 
 All of these have been in linux-next for a while with no reported
 problems.

Ilpo Järvinen 867cae44f8 mfd: intel-m10-bmc: Manage access to MAX 10 fw handshake registers
On some MAX 10 cards, the BMC firmware is not available to service
handshake registers during secure update erase and write phases at
normal speeds. This problem affects at least hwmon driver. When the MAX
10 hwmon driver tries to read the sensor values during a secure update,
the reads are slowed down (e.g., reading all D5005 sensors takes ~24s
which is magnitudes worse than the normal <0.02s).

Manage access to the handshake registers using a rw semaphore and a FW
state variable to prevent accesses during those secure update phases
and return -EBUSY instead.

If handshake_sys_reg_nranges == 0, don't update bwcfw_state as it is not
used. This avoids the locking cost.

fpga: zynq-fpga: Ensure proper xCAP interface switch
The Zynq platform has PCAP, ICAP and JTAG interfaces for configuring
programmable logic (PL). The existing driver implementation uses the
PCAP interface to configure the PL. Before switching the PL configuration
interface from PCAP to ICAP make sure that all outstanding Transactions
relevant to the PL configuration should be completed by the PCAP interface
otherwise it may lead to PL configuration issues.

This patch provides a required fix to ensure that all existing PL
transactions are completed before switching from PCAP to ICAP.

For detailed information relevant to PL configuration interfaces refer
Zynq 7000 TRM (section 6.5.1).

Linus Torvalds cec24b8b6b Char/Misc drivers for 6.4-rc1
Here is the "big" set of char/misc and other driver subsystems for
 6.4-rc1.
 
 It's pretty big, but due to the removal of pcmcia drivers, almost breaks
 even for number of lines added vs. removed, a nice change.
 
 Included in here are:
   - removal of unused PCMCIA drivers (finally!)
   - Interconnect driver updates and additions
   - Lots of IIO driver updates and additions
   - MHI driver updates
   - Coresight driver updates
   - NVMEM driver updates, which required some OF updates
   - W1 driver updates and a new maintainer to manage the subsystem
   - FPGA driver updates
   - New driver subsystem, CDX, for AMD systems
   - lots of other small driver updates and additions
 
 All of these have been in linux-next for a while with no reported
 issues.

Linus Torvalds 556eb8b791 Driver core changes for 6.4-rc1
Here is the large set of driver core changes for 6.4-rc1.
 
 Once again, a busy development cycle, with lots of changes happening in
 the driver core in the quest to be able to move "struct bus" and "struct
 class" into read-only memory, a task now complete with these changes.
 
 This will make the future rust interactions with the driver core more
 "provably correct" as well as providing more obvious lifetime rules for
 all busses and classes in the kernel.
 
 The changes required for this did touch many individual classes and
 busses as many callbacks were changed to take const * parameters
 instead.  All of these changes have been submitted to the various
 subsystem maintainers, giving them plenty of time to review, and most of
 them actually did so.
 
 Other than those changes, included in here are a small set of other
 things:
   - kobject logging improvements
   - cacheinfo improvements and updates
   - obligatory fw_devlink updates and fixes
   - documentation updates
   - device property cleanups and const * changes
   - firwmare loader dependency fixes.
 
 All of these have been in linux-next for a while with no reported
 problems.

fpga: bridge: properly initialize bridge device before populating children
The current code path can lead to warnings because of uninitialized device,
which contains, as a consequence, uninitialized kobject. The uninitialized
device is passed to of_platform_populate, which will at some point, while
creating child device, try to get a reference on uninitialized parent,
resulting in the following warning:

kobject: '(null)' ((ptrval)): is not initialized, yet kobject_get() is
being called.

The warning is observed after migrating a kernel 5.10.x to 6.1.x.
Reverting commit 0d70af3c25 ("fpga: bridge: Use standard dev_release for
class driver") seems to remove the warning.
This commit aggregates device_initialize() and device_add() into
device_register() but this new call is done AFTER of_platform_populate

fpga: xilinx-pr-decoupler: Use readl wrapper instead of pure readl
Driver has IO wrappers but xlnx_pr_decouple_read() is not used and readl is
used instead which is just wrong.
It is also generating sparse issue that xlnx_pr_decouple_read() is unused.

Greg Kroah-Hartman 1aaba11da9 driver core: class: remove module * from class_create()
The module pointer in class_create() never actually did anything, and it
shouldn't have been requred to be set as a parameter even if it did
something.  So just remove it and fix up all callers of the function in
the kernel tree at the same time.

fpga: dfl-pci: Drop redundant pci_enable_pcie_error_reporting()
pci_enable_pcie_error_reporting() enables the device to send ERR_*
Messages.  Since f26e58bf6f ("PCI/AER: Enable error reporting when AER is
native"), the PCI core does this for all devices during enumeration, so the
driver doesn't need to do it itself.

Remove the redundant pci_enable_pcie_error_reporting() call from the
driver.  Also remove the corresponding pci_disable_pcie_error_reporting()
from the driver .remove() path.

Note that this only controls ERR_* Messages from the device.  An ERR_*
Message may cause the Root Port to generate an interrupt, depending on the
AER Root Error Command register managed by the AER service driver.

Linus Torvalds a93e884edf Driver core changes for 6.3-rc1
Here is the large set of driver core changes for 6.3-rc1.
 
 There's a lot of changes this development cycle, most of the work falls
 into two different categories:
   - fw_devlink fixes and updates.  This has gone through numerous review
     cycles and lots of review and testing by lots of different devices.
     Hopefully all should be good now, and Saravana will be keeping a
     watch for any potential regression on odd embedded systems.
   - driver core changes to work to make struct bus_type able to be moved
     into read-only memory (i.e. const)  The recent work with Rust has
     pointed out a number of areas in the driver core where we are
     passing around and working with structures that really do not have
     to be dynamic at all, and they should be able to be read-only making
     things safer overall.  This is the contuation of that work (started
     last release with kobject changes) in moving struct bus_type to be
     constant.  We didn't quite make it for this release, but the
     remaining patches will be finished up for the release after this
     one, but the groundwork has been laid for this effort.
 
 Other than that we have in here:
   - debugfs memory leak fixes in some subsystems
   - error path cleanups and fixes for some never-able-to-be-hit
     codepaths.
   - cacheinfo rework and fixes
   - Other tiny fixes, full details are in the shortlog
 
 All of these have been in linux-next for a while with no reported
 problems.

Ilpo Järvinen acf63c458b fpga: m10bmc-sec: Add support for N6000
Add support for PMCI-based flash access path and N6000 sec update
support. Access to flash staging area is different for N6000 from that
of the SPI interfaced counterparts.

Introduce intel_m10bmc_flash_bulk_ops to allow interface specific
differentiations for the flash access path for sec update and make
m10bmc_sec_read/write() in sec update driver to use the new operations.
The .flash_mutex serializes read/read. Flash update (erase+write) must
use ->lock/unlock_write() to prevent reads during update (reads would
timeout on setting flash MUX as BMC will prevent it).

Create a type specific RSU status reg handler for N6000 because the
field has moved from doorbell to auth result register.

If a failure is detected while altering the flash MUX, it seems safer
to try to set it back and doesn't seem harmful. Likely there are enough
troubles in that case anyway so setting it back fails too (which is
harmless sans the small extra delay) or just confirms that the value
wasn't changed.

fpga: bridge: return errors in the show() method of the "state" attribute
This patch changes the show() method of the "state" sysfs attribute to
propagate errors returned by the enable_show() op. In this way,
userspace can distinguish between when the bridge is actually "enabled"
(i.e., allowing signals) or "disabled" (i.e., gating signals), or when
there is an error.

Currently, enable_show() returns an integer representing the bridge's
state (enabled or disabled) or an error code. However, this integer
value is interpreted in state_show() as a bool, resulting in the method
printing "enabled" (i.e., the bridge allows signals to pass), without
propagating the error, even when enable_show() returns an error code.

While at it, fix polling stop condition to met function's original

condition is that it stops if any of mask bits is set, while intention
was to stop if all mask bits is set. This was not noticible because only

As spi-summary doc says:
 > I/O buffers use the usual Linux rules, and must be DMA-safe.
 > You'd normally allocate them from the heap or free page pool.
 > Don't use the stack, or anything that's declared "static".

Replace spi_write() with spi_write_then_read(), which is dma-safe for
on-stack buffers. Use cacheline aligned buffers for transfers used in
spi_sync_transfer().

Although everything works OK with stack-located I/O buffers, better
follow the doc to be safe.

Russ Weight dfd1033259
fpga: m10bmc-sec: Fix kconfig dependencies
The secure update driver depends on the firmware-upload functionality of
the firmware-loader. The firmware-loader is carried in the firmware-class
driver which is enabled with the tristate CONFIG_FW_LOADER option. The
firmware-upload functionality is included in the firmware-class driver if
the bool FW_UPLOAD config is set.

The current dependency statement, "depends on FW_UPLOAD", is not adequate
because it does not implicitly turn on FW_LOADER. Instead of adding a
dependency, follow the convention used by drivers that require the
FW_LOADER_USER_HELPER functionality of the firmware-loader by using
select for both FW_LOADER and FW_UPLOAD.

fpga: lattice-sysconfig-spi: add Lattice sysCONFIG FPGA manager
Add support to the FPGA manager for programming Lattice ECP5 FPGA over
slave SPI sysCONFIG interface.

sysCONFIG interface core functionality is separate from both ECP5 and
SPI specifics, so support for other FPGAs with different port types can
be added in the future.

fpga: zynq: Switch to use dev_err_probe() helper
In the probe path, dev_err() can be replaced with dev_err_probe()
which will check if error code is -EPROBE_DEFER and prints the
error name. It also sets the defer probe reason which can be
checked later through debugfs. It's more simple in error path.

fpga: m10bmc-sec: Fix possible memory leak of flash_buf
There is an error check following the allocation of flash_buf that returns
without freeing flash_buf. It makes more sense to do the error check
before the allocation and the reordering eliminates the memory leak.

Add a driver name for the D5005 BMC secure update driver. Different
driver names are used for the N3000 and D5005 devices because future
changes will add conditional code based on the device type (N3000
vs D5005). This change enables D5005 secure updates of BCM images,
BMC firmware, static-region images, etc.
