Merge tag 'stmp-dev' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull arm-soc stmp-dev library code from Olof Johansson: "A number of devices are using a common register layout, this adds support code for it in lib/stmp_device.c so we do not need to duplicate it in each driver." Fix up trivial conflicts in drivers/i2c/busses/i2c-mxs.c and lib/Makefile * tag 'stmp-dev' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: i2c: mxs: use global reset function lib: add support for stmp-style devices
