The newly added driver tries to 'select' a symbol that it has an
implicit dependency on, which confuses Kconfig:
subsection "Kconfig recursive dependency limitations"
drivers/remoteproc/Kconfig:3: symbol REMOTEPROC is selected by QCOM_ADSP_PIL
As REMOTEPROC is itself user-visible, we clearly should not select
it from a driver, removing the line fixes the problem.

The tie between the main WCNSS driver and the IRIS driver causes a
circular dependency between the two modules. Neither part makes sense to
have on their own so lets merge them into one module.
For the sake of picking up the clock and regulator resources described
in the iris of_node we need an associated struct device. But, to keep
the size of the patch down we continue to represent the IRIS part as its
own platform_driver, within the same module, rather than setting up a
dummy device.

As all vdev resources are allocated before we boot the remote processor
we no longer need to support modifying the resource table while the
remote is running.
This saves us from the table_ptr dance, but more importantly allow the
remote processor to enable security lock down of the loaded table memory
region.

Vrings are now allocated as we parse the resource table, before we

Instead of having the vrings being allocated and freed as they are
requested by the virtio device tie their life cycle to the vdev
resource. This allows us to decouple the vdev resource management from

Allow the associated smd edge to be described within the wcnss

The newly added st_fdma driver introduces a build warning for
allmodconfig when we add '-Wmaybe-uninitialized':
drivers/dma/st_fdma.c: In function 'st_fdma_probe':
drivers/dma/st_fdma.c:777:5: error: 'ret' may be used uninitialized in this function [-Werror=maybe-uninitialized]
The warning is correct, though this can't happen in practice
as the check is redundant (we don't get to this function if
the pointer is NULL). Even if the function were called with a
NULL of_node, the check is not needed because of_property_read_u32
can deal with a NULL argument by returning an error.
Removing the unnecessary code simplifies the function and avoids
the condition that we get the warning for.

Make REMOTEPROC core a selectable kconfig option, and update
remoteproc client drivers to 'depends on' the core. This avoids
some nasty Kconfig recursive dependency issues. Also when using
menuconfig client drivers will be hidden until the core has been
enabled.
Documentation/kbuild/kconfig-language.txt:
Note:
select should be used with care. select will force
a symbol to a value without visiting the dependencies.
By abusing select you are able to select a symbol FOO even
if FOO depends on BAR that is not set.
In general use select only for non-visible symbols
(no prompts anywhere) and for symbols with no dependencies.
That will limit the usefulness but on the other hand avoid
the illegal configurations all over.

slim core is used as a basis for many IPs in the STi
chipsets such as fdma and demux. To avoid duplicating
the elf loading code in each device driver a slim
rproc driver has been created.
This driver is designed to be used by other device drivers
such as fdma, or demux whose IP is based around a slim core.
The device driver can call slim_rproc_alloc() to allocate
a slim rproc and slim_rproc_put() when finished.
This driver takes care of ioremapping the slim
registers (dmem, imem, slimcore, peripherals), whose offsets
and sizes can change between IP's. It also obtains and enables
any clocks used by the device. This approach avoids having
a double mapping of the registers as slim_rproc does not register
its own platform device. It also maps well to device tree
abstraction as it allows us to have one dt node for the whole
device.
All of the generic rproc elf loading code can be reused, and
we provide start() stop() hooks to start and stop the slim
core once the firmware has been loaded. This has been tested
successfully with fdma driver.

sb_wait_write()->percpu_rwsem_release() fools lockdep to avoid the
false-positives. Now that xfs was fixed by Dave's commit dbad7c993053
("xfs: stop holding ILOCK over filldir callbacks") we can remove it and
change freeze_super() and thaw_super() to run with s_writers.rw_sem locks
held; we add two trivial helpers for that, lockdep_sb_freeze_release()
and lockdep_sb_freeze_acquire().
xfstests-dev/check `grep -il freeze tests/*/???` does not trigger any
warning from lockdep.
