* i2c: Split I2C_M_NOSTART support out of I2C_FUNC_PROTOCOL_MANGLINGMark Brown2012-05-30
| | | | | | | | | | | | | | | | | | Since there are uses for I2C_M_NOSTART which are much more sensible and standard than most of the protocol mangling functionality (the main one being gather writes to devices where something like a register address needs to be inserted before a block of data) create a new I2C_FUNC_NOSTART for this feature and update all the users to use it. Also strengthen the disrecommendation of the protocol mangling while we're at it. In the case of regmap-i2c we remove the requirement for mangling as I2C_M_NOSTART is the only mangling feature which is being used.

* i2c-dev: Add support for I2C_M_RECV_LENJean Delvare2012-05-30
| | | | | | | | | | | | | | As the bus driver side implementation of I2C_M_RECV_LEN is heavily tied to SMBus, we can't support received length over 32 bytes, but let's at least support that. In practice, the caller will have to setup a buffer large enough to cover the case where received length byte has value 32, so minimum 32 + 1 = 33 bytes, possibly more if there is a fixed number of bytes added for the specific slave (for example a checksum.)

I tried hard to make sure the bindings are proper. In more complicated cases, I requested acks from people having more experience with them than me. That took a bit of extra time and also some time went into discussions with developers about what bindings are and what not. I have the feeling that the workflow with bindings should be improved to scale better. I will spend some more thought on this... - i2c-muxes are succesfully used meanwhile, so we dropped EXPERIMENTAL for them and renamed the drivers to a standard pattern to match the rest of the subsystem. They can also be used with devicetree now. - ixp2000 was removed since the whole platform goes away. - cleanups (strlcpy instead of strcpy, NULL instead of 0) - The rest is typical driver fixes I assume. All patches have been in linux-next at least since v3.4-rc6." Fixed up trivial conflict in arch/arm/mach-lpc32xx/common.c due to the same patch already having come in through the arm/soc trees, with additional patches on top of it. * 'i2c-embedded/for-next' of git://git.pengutronix.de/git/wsa/linux: (35 commits) i2c: davinci: Free requested IRQ in remove i2c: ocores: register OF i2c devices i2c: tegra: notify transfer-complete after clearing status.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * i2c/of: Automatically populate i2c mux busses from device tree data.David Daney2012-05-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Main highlights are: - Support for the NX crypto engine in Power7+ - A bunch of Anton goodness, including some micro optimization of our syscall entry on Power7 - I converted a pile of our thermal control drivers to the new i2c APIs (essentially turning the old therm_pm72 into a proper set of windfarm drivers). That's one more step toward removing the deprecated i2c APIs, there's still a few drivers to fix, but we are getting close - kexec/kdump support for 47x embedded cores The big missing thing here is no updates from Freescale. Not sure what's up here, but with Kumar not working for them anymore things are a bit in a state of flux in that area." * 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: (71 commits) powerpc: Fix irq distribution Revert "powerpc/hw-breakpoint: Use generic hw-breakpoint interfaces for new PPC ptrace flags" powerpc: Fixing a cputhread code documentation powerpc/crypto: Enable the PFO-based encryption device powerpc/crypto: Build files for the nx device driver powerpc/crypto: debugfs routines and docs for the nx device driver powerpc/crypto: SHA512 hash routines for nx encryption powerpc/crypto: SHA256 hash routines for nx encryption powerpc/crypto: AES-XCBC mode routines for nx encryption powerpc/crypto: AES-GCM mode routines for nx encryption powerpc/crypto: AES-ECB mode routines for nx encryption powerpc/crypto: AES-CTR mode routines for nx encryption powerpc/crypto: AES-CCM mode routines for nx encryption powerpc/crypto: AES-CBC mode routines for nx encryption powerpc/crypto: nx driver code supporting nx encryption powerpc/pseries: Enable the PFO-based RNG accelerator powerpc/pseries/hwrng: PFO-based hwrng driver powerpc/pseries: Add PFO support to the VIO bus powerpc/pseries: Add pseries update notifier for OFDT prop changes powerpc/pseries: Add new hvcall constants to support PFO ...

| * | | | i2c/powermac: Register i2c devices from device-treeBenjamin Herrenschmidt2012-04-30
| | |/ / | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
