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."
