Merge branch 'stmp_device' of git://git.pengutronix.de/git/wsa/linux into next/stmp-dev
Wolfram Sang <w.sang@pengutronix.de> writes:
This series makes support for a certain type of devices mach independant. We
want that because such devices (having a special register layout) have been
found in mach-mxs and mach-mx6 meanwhile.
Since there is no subsystem maintainer for lib/ and the use case is
currently only for ARM systems, I have agreed to merge these through
the arm-soc tree.
* 'stmp_device' of git://git.pengutronix.de/git/wsa/linux:
i2c: mxs: use global reset function
lib: add support for stmp-style devices
