Merge branch 'i2c/for-4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang: - Peter Rosin did some major rework on the locking of i2c muxes by seperating parent-locked muxes and mux-locked muxes. This avoids deadlocks/workarounds when the mux itself needs i2c commands for muxing. And as a side-effect, other workarounds in the media layer could be eliminated. Also, Peter stepped up as the i2c mux maintainer and will keep an eye on these changes. - major updates to the octeon driver - add a helper to the core to generate the address+rw_bit octal and make drivers use it - quite a bunch of driver updates * 'i2c/for-4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (84 commits) i2c: rcar: add DMA support i2c: st: Implement bus clear i2c: only check scl functions when using generic recovery i2c: algo-bit: declare i2c_bit_quirk_no_clk_stretch as static i2c: tegra: disable clock before returning error [media] rtl2832: regmap is aware of lockdep, drop local locking hack [media] rtl2832_sdr: get rid of empty regmap wrappers [media] rtl2832: change the i2c gate to be mux-locked [media] si2168: change the i2c gate to be mux-locked iio: imu: inv_mpu6050: change the i2c gate to be mux-locked i2c: mux: document i2c muxes and elaborate on parent-/mux-locked muxes i2c: mux: relax locking of the top i2c adapter during mux-locked muxing i2c: muxes always lock the parent adapter i2c: allow adapter drivers to override the adapter locking i2c: uniphier: add "\n" at the end of error log i2c: mv64xxx: remove CONFIG_HAVE_CLK conditionals i2c: mv64xxx: use clk_{prepare_enable,disable_unprepare} i2c: mv64xxx: handle probe deferral for the clock i2c: mv64xxx: enable the driver on ARCH_MVEBU i2c: octeon: Add workaround for broken irqs on CN3860 ...
