Merge branch 'i2c/for-4.15' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang: "This contains two bigger than usual tree-wide changes this time. They all have proper acks, caused no merge conflicts in linux-next where they have been for a while. They are namely: - to-gpiod conversion of the i2c-gpio driver and its users (touching arch/* and drivers/mfd/*) - adding a sbs-manager based on I2C core updates to SMBus alerts (touching drivers/power/*) Other notable changes: - i2c_boardinfo can now carry a dev_name to be used when the device is created. This is because some devices in ACPI world need fixed names to find the regulators. - the designware driver got a long discussed overhaul of its PM handling. img-scb and davinci got PM support, too. - at24 driver has way better OF support. And it has a new maintainer. Thanks Bartosz for stepping up! The rest is regular driver updates and fixes" * 'i2c/for-4.15' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (55 commits) ARM: sa1100: simpad: Correct I2C GPIO offsets i2c: aspeed: Deassert reset in probe eeprom: at24: Add OF device ID table MAINTAINERS: new maintainer for AT24 driver i2c: nuc900: remove platform_data, too i2c: thunderx: Remove duplicate NULL check i2c: taos-evm: Remove duplicate NULL check i2c: Make i2c_unregister_device() NULL-aware i2c: xgene-slimpro: Support v2 i2c: mpc: remove useless variable initialization i2c: omap: Trigger bus recovery in lockup case i2c: gpio: Add support for named gpios in DT dt-bindings: i2c: i2c-gpio: Add support for named gpios i2c: gpio: Local vars in probe i2c: gpio: Augment all boardfiles to use open drain i2c: gpio: Enforce open drain through gpiolib gpio: Make it possible for consumers to enforce open drain i2c: gpio: Convert to use descriptors power: supply: sbs-message: fix some code style issues power: supply: sbs-battery: remove unchecked return var ...
