2009-09-18i2c: Clearly mark ACPI drivers as suchJean Delvare
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. This is exactly the same as we just did for hwmon drivers. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Crane Cai <crane.cai@amd.com>

2008-10-14i2c: Renesas Highlander FPGA SMBus supportPaul Mundt
This adds support for the SMBus adapter found in the various FPGAs on the Renesas Highlander platforms. Particularly the R0P7780LC0011RL and R0P7785LC0011RL FPGAs. Functionality is fairly restricted, in that only byte and block data transfers are supported. Normal/fast mode and IRQ/polling are also supported. Primarily used for various RTCs and thermal sensors.

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.

2006-01-09[PATCH] 2/5 powerpc: Rework PowerMac i2c part 2Benjamin Herrenschmidt
This is the continuation of the previous patch. This one removes the old PowerMac i2c drivers (i2c-keywest and i2c-pmac-smu) and replaces them both with a single stub driver that uses the new PowerMac low i2c layer. Now that i2c-keywest is gone, the low-i2c code is extended to support interrupt driver transfers. All i2c busses now appear as platform devices. Compatibility with existing drivers should be maintained as the i2c bus names have been kept identical, except for the SMU bus but in that later case, all users has been fixed. With that patch added, matching a device node to an i2c_adapter becomes trivial. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-09-22[PATCH] ppc64: SMU driver update & i2c supportBenjamin Herrenschmidt
The SMU is the "system controller" chip used by Apple recent G5 machines including the iMac G5. It drives things like fans, i2c busses, real time clock, etc... The current kernel contains a very crude driver that doesn't do much more than reading the real time clock synchronously. This is a completely rewritten driver that provides interrupt based command queuing, a userland interface, and an i2c/smbus driver for accessing the devices hanging off the SMU i2c busses like temperature sensors. This driver is a basic block for upcoming work on thermal control for those machines, among others.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
