Pull char / misc / IIO / other driver updates from Greg KH:
"Here is the big set of char/misc/iio and other smaller driver
subsystems for 6.17-rc1. It's a big set this time around, with the
huge majority being in the iio subsystem with new drivers and dts
files being added there.
Highlights include:
- IIO driver updates, additions, and changes making more code const
and cleaning up some init logic
- bus_type constant conversion changes
- misc device test functions added
- rust miscdevice minor fixup
- unused function removals for some drivers
- mei driver updates
- mhi driver updates
- interconnect driver updates
- Android binder updates and test infrastructure added
- small cdx driver updates
- small comedi fixes
- small nvmem driver updates
- small pps driver updates
- some acrn virt driver fixes for printk messages
- other small driver updates
All of these have been in linux-next with no reported issues"

of_node_to_fwnode() is an irqdomain's reimplementation of the
"officially" defined of_fwnode_handle(). The former is in the process of
being removed, so use the latter instead.
This is the last in-tree user.

struct gpio_chip now has callbacks for setting line values that return
an integer, allowing to indicate failures. Convert the driver to using
them.

As of commit 92ac7de3175e3 ("gpiolib: don't allow setting values on input
lines"), the GPIO core makes sure values cannot be set on input lines.
Remove the unnecessary check.

Some I2C ATRs do not support dynamic remapping, only static mapping
of direct children.
Mappings will only be added or removed as a result of devices being
added or removed from a child bus.
The ATR pool will have to be big enough to accommodate all devices
expected to be added to the child buses.
Add a new flag that prevents old mappings to be replaced or new mappings
to be created in the alias finding code paths. That mens adding a flags
parameter to i2c_atr_new() and an i2c_atr_flags enum.

The TI FPC202 dual port controller serves as a low-speed signal aggregator
for common port types such as SFP, QSFP, Mini-SAS HD, and others.
It aggregates GPIO and I2C signals across two downstream ports, acting as
both a GPIO controller and an I2C address translator for up to two logical
devices per port.
