These changes have no effect if CONFIG_GCOV_KERNEL is not set in defconfig. It is easier to trigger GCOV for kernel if this patch is in by only setting the before mentioned flag.

2011-03-21i2c-pxa2xx: Add PCI support for PXA I2C controllerSebastian Andrzej Siewior
The Sodaville I2C controller is almost the same as found on PXA2xx. The difference: - the register are at a different offset - no slave support The PCI probe code adds three platform devices which are probed then by the platform code. The X86 part also adds dummy clock defines because we don't have HW clock support.

2010-10-28i2c-intel-mid: support for Moorestown and Medfield platformAlan Cox
(Updated to address Ben's comments. With regard to the message segment restriction it's not something we hit on the actual platform so while I will investigate that further I don't think its a blocker to submission. At worst its a spot over-restrictive) From: Wen Wang <wen.w.wang@intel.com> Initial release of the driver. Updated and verified on hardware. Cleaned up as follows Alan Cox: Squash down the switches into tables, and use the PCI ident field. We could perhaps take this further and put the platform and port number into this. uint32t -> u32 bracketing of case statements spacing and '!' usage Check the speed (which is now 0/1/2) is valid and ignore otherwise. Fix remaining problems/suggestions from Jean's review Fix items from Ben's review Arjan van de Ven: Initial power management hooks Yong Wang <youg.y.wang@intel.com>: Shared IRQ support Wen Wang <wen.w.wang@intel.com>: D3 support Fixes for OCT test runs Interrupt optimisations Hong Liu <hong.liu@intel.com> The runtime PM code is working on the wrong device (i2c_adapter->dev). The correct one should be pci_dev->dev. This breaks attached i2c slave devices with runtime PM enabled. Slave device needs to runtime resume parent device before runtime resuming itself, but we always get error since we don't have pm_runtime callback for i2c_adapter->dev.

2008-07-14i2c-nforce2: Add support for multiplexing on the Tyan S4985Jean Delvare
Just like the Tyan S4882, the S4985 uses a multiplexer to give access to all 16 memory module SPD EEPROMs. This specific i2c-nforce2-s4985 driver adds support for this. It is heavily based on the older i2c-amd756-s4882 driver. As more mainboards will use multiplexer chips, we will have to find a way to support them without having to write a new specfic driver for each. The recent changes to the i2c subsystem should help us, and the new gpio subsystem might help, too. Signed-off-by: Jean Delvare <khali@linux-fr.org>

2007-05-01i2c: Bitbanging I2C bus driver using the GPIO APIHaavard Skinnemoen
This is a very simple bitbanging I2C bus driver utilizing the new arch-neutral GPIO API. Useful for chips that don't have a built-in I2C controller, additional I2C busses, or testing purposes. To use, include something similar to the following in the board-specific setup code: #include <linux/i2c-gpio.h> static struct i2c_gpio_platform_data i2c_gpio_data = { .sda_pin = GPIO_PIN_FOO, .scl_pin = GPIO_PIN_BAR, }; static struct platform_device i2c_gpio_device = { .name = "i2c-gpio", .id = 0, .dev = { .platform_data = &i2c_gpio_data, }, }; Register this platform_device, set up the I2C pins as GPIO if required and you're ready to go. This will use default values for udelay and timeout, and will work with GPIO hardware that does not support open drain mode, but allows sensing of the SDA and SCL lines even when they are being driven.
