Merge branch 'i2c-embedded/for-next' of git://git.pengutronix.de/git/wsa/linux
Pull i2c-embedded changes from Wolfram Sang: "The changes for i2c-embedded include: - massive rework of the omap driver - massive rework of the at91 driver. In fact, the old driver gets removed; I am okay with this approach since the old driver was depending on BROKEN and its limitations made it practically unusable, so people used bitbanging instead. But even if there are users, there is no platform_data or module parameter which would need to be converted. It is just another driver doing I2C transfers, just way better. Modifications of arch/arm/at91 related files have proper acks from the maintainer. - new driver for R-Car I2C - devicetree and generic_clock conversions and fixes - usual driver fixes and changes. The rework patches have come a long way and lots of people have been involved in creating/testing them. Most patches have been in linux-next at least since 3.6-rc5. A few have been added in the last week, I have to admit. An unexpected (but welcome :)) peak in private life is the cause for that. The "late" patches shouldn't cause any merge conflicts and I will have a special eye on them during the stabilization phase. This is an exception and I want to have the patches in place properly in time again for the next kernels." * 'i2c-embedded/for-next' of git://git.pengutronix.de/git/wsa/linux: (44 commits) MXS: Implement DMA support into mxs-i2c i2c: add Renesas R-Car I2C driver i2c: s3c2410: use clk_prepare_enable and clk_disable_unprepare ARM: OMAP: convert I2C driver to PM QoS for MPU latency constraints i2c: nomadik: Add Device Tree support to the Nomadik I2C driver i2c: algo: pca: Fix chip reset function for PCA9665 i2c: mpc: Wait for STOP to hit the bus i2c: davinci: preparation for switch to common clock framework omap-i2c: fix incorrect log message when using a device tree i2c: omap: sanitize exit path i2c: omap: switch over to autosuspend API i2c: omap: remove unnecessary pm_runtime_suspended check i2c: omap: switch to threaded IRQ support i2c: omap: remove redundant status read i2c: omap: get rid of the "complete" label i2c: omap: resize fifos before each message i2c: omap: simplify IRQ exit path i2c: omap: always return IRQ_HANDLED i2c: omap: simplify errata check i2c: omap: bus: add a receiver flag ...
