Merge branch 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c changes from Wolfram Sang: - an arbitration driver. While the driver is quite simple, it caused discussion if we need additional arbitration on top of the one specified in the I2C standard. Conclusion is that I accept a few generic mechanisms, but not very specific ones. - the core lost the detach_adapter() call. It has no users anymore and was in the way for other cleanups. attach_adapter() is sadly still there since there are users waiting to be converted. - the core gained a bus recovery infrastructure. I2C defines a way to recover if the data line is stalled. This mechanism is now in the core and drivers can now pass some data to make use of it. - bigger driver cleanups for designware, s3c2410 - removing superfluous refcounting from drivers - removing Ben Dooks as second maintainer due to inactivity. Thanks for all your work so far, Ben! - bugfixes, feature additions, devicetree fixups, simplifications... * 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (38 commits) i2c: xiic: must always write 16-bit words to TX_FIFO i2c: octeon: use HZ in timeout value i2c: octeon: Fix i2c fail problem when a process is terminated by a signal i2c: designware-pci: drop superfluous {get|put}_device i2c: designware-plat: drop superfluous {get|put}_device i2c: davinci: drop superfluous {get|put}_device MAINTAINERS: Ben Dooks is inactive regarding I2C i2c: mux: Add i2c-arb-gpio-challenge 'mux' driver i2c: at91: convert to dma_request_slave_channel_compat() i2c: mxs: do error checking and handling in PIO mode i2c: mxs: remove races in PIO code i2c-designware: switch to use runtime PM autosuspend i2c-designware: use usleep_range() in the busy-loop i2c-designware: enable/disable the controller properly i2c-designware: use dynamic adapter numbering on Lynxpoint i2c-designware-pci: use managed functions pcim_* and devm_* i2c-designware-pci: use dev_err() instead of printk() i2c-designware: move to managed functions (devm_*) i2c: remove CONFIG_HOTPLUG ifdefs i2c: s3c2410: Add SMBus emulation for block read ...
