Pull i2c updates from Wolfram Sang:
"i2c core:
- huge improvements and refactorizations of the Linux I2C
documentation (lots of thanks to Luca for doing it and Jean for the
careful review)
- subsystem wide API conversion to i2c_new_client_device()
- remove obsolete parport-light driver
- smaller core updates (removal of 'extern', enabling more compile
testing, use more helper macros)
- and quite a bunch of driver updates (new IDs, simplifications,
better PM, support of atomic transfers and other improvements)
i2c-mux:
- The main feature is the idle-state rework of the pca954x driver
from Biwen Li
at24 driver:
- minor maintenance: update the license tag, sort headers
- move support for the write-protect pin into nvmem core
- add a reference to the new wp-gpios property in nvmem to at25
bindings
- add support for regulator and pm_runtime control"

Some i2c controllers have a built-in digital or analog filter.
This is specifically required depending on the hardware PCB/board.
Some controllers also allow specifying the maximum width of the
spikes that can be filtered for digital filter. The width length can be
specified in nanoseconds.
Analog filters can be configured to have a cutoff frequency (low-pass filter).
This frequency can be specified in Hz.
Added an optional property for such types of analog filters.

Even though the binding claims that the frequency can go up to 6MHz, the
common i2c binding sets a limit at 3MHz, which then triggers a warning.

"The biggest highlight here is the start of using json-schema for DT
bindings. Being able to validate bindings has been discussed for years
with little progress.
- Initial support for DT bindings using json-schema language. This is
the start of converting DT bindings from free-form text to a
structured format.
- Reworking of initrd address initialization. This moves to using the
phys address instead of virt addr in the DT parsing code. This
rework was motivated by CONFIG_DEV_BLK_INITRD causing unnecessary
rebuilding of lots of files.
- Fix stale phandle entries in phandle cache
- DT overlay validation improvements. This exposed several memory
leak bugs which have been fixed.
- Use node name and device_type helper functions in DT code
- Last remaining conversions to using %pOFn printk specifier instead
of device_node.name directly
- Create new common RTC binding doc and move all trivial RTC devices
out of trivial-devices.txt.

'interrupt-parent' is often documented as part of define bindings, but
it is really outside the scope of a device binding. It's never required
in a given node as it is often inherited from a parent node. Or it can
be implicit if a parent node is an 'interrupt-controller' node. So
remove it from all the binding files.

controller, MT2712 has timing adjust registers which can adjust
the internal divider of i2c source clock, SCL duty cycle, SCL
compare point, start(repeated start) and stop time, SDA change
time.

Merge tag 'at24-4.16-updates-for-wolfram' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux into i2c/for-4.16
"AT24 updates for 4.16 merge window
The driver has been converted to using regmap instead of raw i2c and
smbus calls which shrank the code significantly.
Device tree binding document has been cleaned up. Device tree support in
the driver has been improved and we now support all at24 models as well
as two new DT properties (no-read-rollover and wp-gpios).
We no longer user unreadable magic values for driver data as the way it
was implemented caused problems for some EEPROM models - we switched to
regular structs.
Aside from that, there's a bunch of coding style fixes and minor
improvements all over the place."
This patch extends the current i2c-mux-pca954x driver and adds support for
a newer PCA984x family of the I2C switches and multiplexers from NXP.

DT unit addresses should be lower case hex. Fix all the
binding examples.
