Merge branch 'i2c-embedded/for-next' of git://git.pengutronix.de/git/wsa/linux
Pull embedded i2c changes from Wolfram Sang: "Changes for the "embedded" part of the I2C subsystem: - lots of devicetree conversions of drivers (and preparations for that) - big cleanups for drivers for OMAP, Tegra, Nomadik, Blackfin - Rafael's struct dev_pm_ops conversion patches for I2C - usual driver cleanups and fixes All patches have been in linux-next for an apropriate time and all patches touching files outside of i2c-folders should have proper acks from the maintainers." * 'i2c-embedded/for-next' of git://git.pengutronix.de/git/wsa/linux: (60 commits) Revert "i2c: tegra: convert normal suspend/resume to *_noirq" I2C: MV64XYZ: Add Device Tree support i2c: stu300: use devm managed resources i2c: i2c-ocores: support for 16bit and 32bit IO V4L/DVB: mfd: use reg_shift instead of regstep i2c: i2c-ocores: Use reg-shift property i2c: i2c-ocores: DT bindings and minor fixes. i2c: mv64xxxx: remove EXPERIMENTAL tag i2c-s3c2410: Use plain pm_runtime_put() i2c: s3c2410: Fix pointer type passed to of_match_node() i2c: mxs: Set I2C timing registers for mxs-i2c i2c: i2c-bfin-twi: Move blackfin TWI register access Macro to head file. i2c: i2c-bfin-twi: Move TWI peripheral pin request array to platform data. i2c:i2c-bfin-twi: include twi head file i2c:i2c-bfin-twi: TWI fails to restart next transfer in high system load. i2c: i2c-bfin-twi: Tighten condition when failing I2C transfer if MEN bit is reset unexpectedly. i2c: i2c-bfin-twi: Break dead waiting loop if i2c device misbehaves. i2c: i2c-bfin-twi: Improve the patch for bug "Illegal i2c bus lock upon certain transfer scenarios". i2c: i2c-bfin-twi: Illegal i2c bus lock upon certain transfer scenarios. i2c-mv64xxxx: allow more than one driver instance ...
