We're about to split the current API into two, where consumers will
be forced to be explicit when requesting reset lines. The choice
will be to either the call the *_exclusive or *_shared variant
depending on whether they can actually tolorate not being asserted
when that request is made.
The new API will look like this once reorded and complete:
reset_control_get_exclusive()
reset_control_get_shared()
reset_control_get_optional_exclusive()
reset_control_get_optional_shared()
of_reset_control_get_exclusive()
of_reset_control_get_shared()
of_reset_control_get_exclusive_by_index()
of_reset_control_get_shared_by_index()
devm_reset_control_get_exclusive()
devm_reset_control_get_shared()
devm_reset_control_get_optional_exclusive()
devm_reset_control_get_optional_shared()
devm_reset_control_get_exclusive_by_index()
devm_reset_control_get_shared_by_index()

Current ALSA SoC has simple-card driver which is supporting both
platform and DT probe.
Now, some sound cards driver are created based on simple-card.
They have similar feature or function, but implemented separately
on each drivers. This is a waste of code.
OTOH, merging these driver into same driver is highly risk,
because it will be very difficult to keep compatibility.
More over, ALSA SoC want to have graph base of DT feature in the
future. Maybe it want to use simple-card like feature / function.
Because of these background, this patch creates simple-card
helper utils, and provides common function to each drivers.
1st is asoc_simple_card_parse_daifmt()

usb: patches for v4.8 merge window
Here's the big pull request for Peripheral stack and
all related drivers.
This time around with 109 non-merge commits mostly
concentrated on drivers/usb/gadget/udc (41.5%) and
drivers/usb/dwc3 (28.1%).
There's a big rework on dwc3's transfer handling
which gave us almost 3x faster USB3 speeds with Mass
Storage on a particular test scenario I measured. We
are also removing platform_data from dwc3 after
converting all users to built-in properties instead.
For the Gadget API, we're just adding tracepoints to
aid debugging activities.
Other than these, there's the usual set of spelling
fixes, minor bug fixes and sparse warnings cleanups.

Some devices with a pen may have a switch that can be used to detect
when the pen is inserted or removed to a slot on the device. Let's add
a define to the input event codes so that everyone can be on the same
page for what event we should generate when the pen is inserted or
removed.
In general the pen switch could be used by the software on the device to
kick off any number of actions when the pen is inserted or removed.

On R-Car H1 and Gen2, the SYSC interrupt registers are always configured
using hardcoded values in platform code. For R-Car Gen2, values are
provided for H2 and M2-W only, other SoCs are not yet supported, and
never will be.
Move this configuration from SoC-specific platform code to the
rcar_sysc_init() wrapper, so it can be skipped if the SYSC is configured
from DT. This would be the case not only for H1, H2, and M2-W using a
modern DTS, but also for other R-Car Gen2 SoCs not supported by the
platform code, relying purely on DT.
There is no longer a need to return the mapped register block, hence
make the function return void.

Commit dead9f29ddcc ("perf: Fix race in BPF program unregister") moved
destruction of BPF program from free_event_rcu() callback to __free_event(),
which is problematic if used with tail calls: if prog A is attached as
trace event directly, but at the same time present in a tail call map used
by another trace event program elsewhere, then we need to delay destruction
via RCU grace period since it can still be in use by the program doing the
tail call (the prog first needs to be dropped from the tail call map, then
trace event with prog A attached destroyed, so we get immediate destruction).

The are already cases when pm_genpd_init() can fail. Currently we hide the
failures instead of propagating an error code, which is a better method.
Moreover, to prepare for future changes like moving away from using a
fixed array-size of the struct genpd_power_state, to instead dynamically
allocate data for it, the pm_genpd_init() API needs to be able to return
an error code, as allocation can fail.
Current users of the pm_genpd_init() is thus requested to start dealing
with error codes. In the transition phase, users will have to live with
only error messages being printed to log.

The max8903_charger.h file indicated that dcm and dok were not optional
when dc_valid is set.
It makes sense to have dok as a compulsory pin when dc_valid is given.
However dcm can be optionally wired to a fixed level especially when the
circuit is configured for dc power exclusively.
The previous implementation already allowed for this somewhat, however no
error was given if dok wasn't given whilst dc_valid was.
The new implementation enforces dok presence when dc_valid is given. Whilst
allowing dcm to be optional.

Calling the fixed-phy functions when CONFIG_FIXED_PHY=m as a previous
change tried cannot work if the caller is in built-in code:
drivers/of/built-in.o: In function `of_phy_register_fixed_link':
of_reserved_mem.c:(.text+0x85e0): undefined reference to `fixed_phy_register'
Making of_mdio depend on 'FIXED_PHY || !FIXED_PHY' would solve this
dependency by enforcing that OF_MDIO itself becomes a loadable module
when FIXED_PHY=y, but that creates a different dependency as it
breaks any built-in ethernet driver that uses of_mdio.
Making FIXED_PHY a bool option also cannot work, since it depends on
PHYLIB, which again is tristate.
This version now uses 'select FIXED_PHY' to ensure that the fixed-phy
portion of of_mdio is not optional. The main downside of this is
a small increase in code size for cases that do not need fixed phy
support, but it should avoid all of the link-time problems.

context. This is particularly intended for make the new callbacks for
driver specific events easier for AFU drivers to use, as they can easily
get back to any private data structures they may use.

This adds an afu_driver_ops structure with fetch_event() and
event_delivered() callbacks. An AFU driver such as cxlflash can fill
this out and associate it with a context to enable passing custom AFU
specific events to userspace.
This also adds a new kernel API function cxl_context_pending_events(),
that the AFU driver can use to notify the cxl driver that new specific
events are ready to be delivered, and wake up anyone waiting on the
context wait queue.
The current count of AFU driver specific events is stored in the field
afu_driver_events of the context structure.
The cxl driver checks the afu_driver_events count during poll, select,
read, etc. calls to check if an AFU driver specific event is pending,
and calls fetch_event() to obtain and deliver that event. This way, the
cxl driver takes care of all the usual locking semantics around these
calls and handles all the generic cxl events, so that the AFU driver
only needs to worry about it's own events.
fetch_event() return a struct cxl_event_afu_driver_reserved, allocated
by the AFU driver, and filled in with the specific event information and
size. Total event size (header + data) should not be greater than
CXL_READ_MIN_SIZE (4K).
Th cxl driver prepends an appropriate cxl event header, copies the event
to userspace, and finally calls event_delivered() to return the status of
the operation to the AFU driver. The event is identified by the context
and cxl_event_afu_driver_reserved pointers.
Since AFU drivers provide their own means for userspace to obtain the
AFU file descriptor (i.e. cxlflash uses an ioctl on their scsi file
descriptor to obtain the AFU file descriptor) and the generic cxl driver
will never use this event, the ABI of the event is up to each individual
AFU driver.

All the clocksource drivers's init function are now converted to return
an error code. CLOCKSOURCE_OF_DECLARE is no longer used as well as the
clksrc-of table.
Let's convert back the names:
- CLOCKSOURCE_OF_DECLARE_RET => CLOCKSOURCE_OF_DECLARE
- clksrc-of-ret => clksrc-of

The init functions do not return any error. They behave as the following:
- panic, thus leading to a kernel crash while another timer may work and
make the system boot up correctly
or
- print an error and let the caller unaware if the state of the system
Change that by converting the init functions to return an error conforming
to the CLOCKSOURCE_OF_RET prototype.
Proper error handling (rollback, errno value) will be changed later case
by case, thus this change just return back an error or success in the init
function.
