2012-05-12i2c: muxes: rename first set of drivers to a standard patternWolfram Sang
Apply a naming pattern like in the rest of the subsystem to a first set of mux drivers. Those drivers are the low-hanging fruit; we want to pick them to motivate upcoming drivers to follow the new pattern. The missing GPIO driver will be converted in a later patch.

2012-05-12i2c-s3c2410: Add HDMIPHY quirk for S3C2440Karol Lewandowski
This patch adds support for s3c2440 I2C bus controller dedicated HDMIPHY device on Exynos4 platform. Some quirks are introduced due to differences between HDMIPHY and other I2C controllers on Exynos4. These differences are: - no GPIOs, HDMIPHY is inside the SoC and the controller is connected internally - due to unknown reason (probably HW bug in HDMIPHY and/or the controller) a transfer fails to finish. The controller hangs after sending the last byte, the workaround for this bug is resetting the controller after each transfer Signed-off-by: Tomasz Stanislawski <t.stanislaws@samsung.com> Signed-off-by: Karol Lewandowski <k.lewandowsk@samsung.com> Tested-by: Tomasz Stanislawski <t.stanislaws@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Signed-off-by: Wolfram Sang <w.sang@pengutronix.de>

2012-05-12i2c: muxes are not EXPERIMENTAL anymoreWolfram Sang
We got multiple patches to add mux support to device tree, so people are using it happily already and build up on it.

2012-05-12i2c/of: Automatically populate i2c mux busses from device tree data.David Daney
For 'normal' i2c bus drivers, we can call of_i2c_register_devices() and have the device tree framework automatically populate the bus with the devices specified in the device tree. This patch adds a common code to the i2c mux framework to have the mux sub-busses be populated by the of_i2c_register_devices() too. If the mux device has an of_node, we populate the sub-bus' of_node so that the subsequent call to of_i2c_register_devices() will find the corresponding devices. It seemed better to put this logic in i2c_add_mux_adapter() rather than the individual mux drivers, as they will all probably want to do the same thing.

2012-04-30i2c/powermac: Register i2c devices from device-treeBenjamin Herrenschmidt
This causes i2c-powermac to register i2c devices exposed in the device-tree, enabling new-style probing of devices. Note that we prefix the IDs with "MAC," in order to prevent the generic drivers from matching. This is done on purpose as we only want drivers specifically tested/designed to operate on powermacs to match. This removes the special case we had for the AMS driver, and updates the driver's match table instead. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2012-04-27i2c: mxs: disable QUEUE when sending is doneWolfram Sang
Since the last fixes to this driver ensure now the queue termination is done correctly, we can finally disable the queue after a transfer without problems. The gain is that it will only be reenabled after the next transfer is fully set up. Before, the queue was running all the time and if the setup of the next message was interrupted by another thread, an incomplete buffer could have been sent, padded with zeroes.

git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system Pull "Disintegrate and delete asm/system.h" from David Howells: "Here are a bunch of patches to disintegrate asm/system.h into a set of separate bits to relieve the problem of circular inclusion dependencies. I've built all the working defconfigs from all the arches that I can and made sure that they don't break. The reason for these patches is that I recently encountered a circular dependency problem that came about when I produced some patches to optimise get_order() by rewriting it to use ilog2(). This uses bitops - and on the SH arch asm/bitops.h drags in asm-generic/get_order.h by a circuituous route involving asm/system.h. The main difficulty seems to be asm/system.h. It holds a number of low level bits with no/few dependencies that are commonly used (eg. memory barriers) and a number of bits with more dependencies that aren't used in many places (eg. switch_to()). These patches break asm/system.h up into the following core pieces: (1) asm/barrier.h Move memory barriers here. This already done for MIPS and Alpha. (2) asm/switch_to.h Move switch_to() and related stuff here. (3) asm/exec.h Move arch_align_stack() here. Other process execution related bits could perhaps go here from asm/processor.h. (4) asm/cmpxchg.h Move xchg() and cmpxchg() here as they're full word atomic ops and frequently used by atomic_xchg() and atomic_cmpxchg(). (5) asm/bug.h Move die() and related bits. (6) asm/auxvec.h Move AT_VECTOR_SIZE_ARCH here. Other arch headers are created as needed on a per-arch basis."

2012-03-27Merge tag 'drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-socLinus Torvalds
Pull "ARM: driver specific updates" from Arnd Bergmann: "These are all specific to some driver. They are typically the platform side of a change in the drivers directory, such as adding a new driver or extending the interface to the platform. In cases where there is no maintainer for the driver, or the maintainer prefers to have the platform changes in the same branch as the driver changes, the patches to the drivers are included as well. A much smaller set of driver updates that depend on other branches getting merged first will be sent later. The new export of tegra_chip_uid conflicts with other changes in fuse.c. In rtc-sa1100.c, the global removal of IRQF_DISABLED conflicts with the cleanup of the interrupt handling of that driver.
