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."
