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 ...

i2c: mux: Add i2c-arb-gpio-challenge 'mux' driver

2013-04-17T09:31:03Z

The i2c-arb-gpio-challenge driver implements an I2C arbitration scheme where masters need to claim the bus with a GPIO before they can start a transaction. This should generally only be used when standard I2C multimaster isn't appropriate for some reason (errata/bugs). This driver is based on code that Simon Glass added to the i2c-s3c2410 driver in the Chrome OS kernel 3.4 tree. The current incarnation as a mux driver is as suggested by Grant Likely. See for some history. Signed-off-by: Doug Anderson Signed-off-by: Simon Glass Signed-off-by: Naveen Krishna Chatradhi Reviewed-by: Stephen Warren Acked-by: Olof Johansson Signed-off-by: Wolfram Sang

tpm: Add support for new Infineon I2C TPM (SLB 9645 TT 1.2 I2C)

2013-04-12T17:17:28Z

This driver adds support for Infineon's new SLB 9645 TT 1.2 I2C TPMs, which supports clockstretching, combined reads and a bus speed of up to 400khz. The device also has a new device id. The driver works now also fine with device trees, so you can instantiate your device by adding: + tpm { + compatible = "infineon,slb9645tt"; + reg = <0x20>; + }; for SLB 9645 devices or + tpm { + compatible = "infineon,slb9635tt"; + reg = <0x20>; + }; for SLB 9635 devices to your device tree. tpm_i2c_infineon is also retained as a compatible id as a fallback to slb9635 protocol. The driver was tested on Beaglebone. Signed-off-by: Peter Huewe Signed-off-by: Kent Yoder

Merge tag 'tegra-for-3.10-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra into next/dt2

From Stephen Warren : ARM: tegra: device tree changes This branch contains the majority of the device tree changes for Tegra. Highlights include: * Many changes for Tegra114, and the Dalmore board, to enable pinctrl, SDHCI/MMC, PWM, DMA, I2C, KBC, SPI, battery, regulators. * Adding or enabling suspend wakeup sources on many boards, and adding suspend timing parameters, to support the system suspend patches. * Adding clocks to the audio-related nodes, so that in 3.11, the audio driver can pull these clocks from device tree rather than hard-coding clock names. * Some small DT fixes/cleanup. This branch is based on the previous clk pull request. * tag 'tegra-for-3.10-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra: (25 commits) clk: tegra: Fix cdev1 and cdev2 IDs ARM: dts: tegra: add the PM configurations of PMC ARM: tegra: add non-removable and keep-power-in-suspend property for MMC ARM: tegra: whistler: add wakeup source for KBC ARM: tegra: add power gpio keys to DT ARM: tegra: keep power on to SD slot on Dalmore ARM: tegra: add clocks property to AC'97 sound nodes ARM: tegra: add clocks property to sound nodes ARM: tegra: dalmore: add fixed regulator node ARM: tegra: dalmore: add TPS65090 node ARM: tegra: dalmore: add cpu regulator node ARM: tegra: Add sbs-battery node to Dalmore ARM: tegra: add DT binding for i2c-tegra ARM: tegra: add SPI nodes to Tegra114 DT ARM: tegra: add KBC nodes to Tegra114 DT ARM: tegra: add aliases and DMA requestor for serial nodes of Tegra114 ARM: tegra: add I2C nodes to Tegra114 DT ARM: tegra: add APB DMA nodes to Tegra114 DT ARM: tegra: add PWM nodes to Tegra114 DT ARM: tegra: fix the status of PWM DT nodes ...
