Merge branch 'i2c/for-4.8' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang: "Here is the I2C pull request for 4.8: - the core and i801 driver gained support for SMBus Host Notify - core support for more than one address in DT - i2c_add_adapter() has now better error messages. We can remove all error messages from drivers calling it as a next step. - bigger updates to rk3x driver to support rk3399 SoC - the at24 eeprom driver got refactored and can now read special variants with unique serials or fixed MAC addresses. The rest is regular driver updates and bugfixes" * 'i2c/for-4.8' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (66 commits) i2c: i801: use IS_ENABLED() instead of checking for built-in or module Documentation: i2c: slave: give proper example for pm usage Documentation: i2c: slave: describe buffer problems a bit better i2c: bcm2835: Don't complain on -EPROBE_DEFER from getting our clock i2c: i2c-smbus: drop useless stubs i2c: efm32: fix a failure path in efm32_i2c_probe() Revert "i2c: core: Cleanup I2C ACPI namespace" Revert "i2c: core: Add function for finding the bus speed from ACPI" i2c: Update the description of I2C_SMBUS i2c: i2c-smbus: fix i2c_handle_smbus_host_notify documentation eeprom: at24: tweak the loop_until_timeout() macro eeprom: at24: add support for at24mac series eeprom: at24: support reading the serial number for 24csxx eeprom: at24: platform_data: use BIT() macro eeprom: at24: split at24_eeprom_write() into specialized functions eeprom: at24: split at24_eeprom_read() into specialized functions eeprom: at24: hide the read/write loop behind a macro eeprom: at24: call read/write functions via function pointers eeprom: at24: coding style fixes eeprom: at24: move at24_read() below at24_eeprom_write() ...
