Merge branch 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang: "Highlights: - OF and ACPI helpers are now included in the core, and not in external files anymore. This removes dependency problems for modules and is cleaner, in general. - mv64xxx-driver gains fifo usage to support mv78230 - imx-driver overhaul to support VF610 - various cleanups, most notably related to devm_* and CONFIG_PM usage - driver bugfixes and smaller feature additions" * 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (51 commits) i2c: rcar: add rcar-H2 support i2c: sirf: retry 3 times as sometimes we get random noack and timeout i2c: sirf: support reverse direction of address i2c: sirf: fix the typo for setting bitrate to less than 100k i2c: sirf: we need to wait I2C_RESET status in resume i2c: sirf: reset i2c controller early after we get a noack i2c: designware: get SDA hold time, HCNT and LCNT configuration from ACPI i2c: designware: make HCNT/LCNT values configurable i2c: mpc: cleanup clock API use i2c: pnx: fix error return code in i2c_pnx_probe() i2c: ismt: add error return code in probe() i2c: mv64xxx: fix typo in binding documentation i2c: imx: use exact SoC revision to document binding i2c: move ACPI helpers into the core i2c: move OF helpers into the core i2c: mv64xxx: Fix timing issue on Armada XP (errata FE-8471889) i2c: mv64xxx: Add I2C Transaction Generator support i2c: powermac: fix return path on error Documentation: i2c: Fix example in instantiating-devices i2c: tiny-usb: do not use stack as URB transfer_buffer ...
