由 Alan Cox 提交于
(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.

This patch adds support for the Xilinx XPS IIC Bus Interface. The driver uses the dynamic mode, supporting to put several I2C messages in the FIFO to reduce the number of interrupts. It has the same feature as ocores, it can be passed a list of devices that will be added when the bus is probed.

Now that we have ACPI-based SMBus controller drivers, and we will start telling users to use them instead of native drivers when I/O resources conflict, I think it would be good to clearly mark ACPI drivers as such in Kconfig.

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: NJean Delvare <khali@linux-fr.org>

由 Haavard Skinnemoen 提交于
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.
