2013-11-15i2c: bcm-kona: Introduce Broadcom I2C DriverTim Kryger
Introduce support for Broadcom Serial Controller (BSC) I2C bus found in the Kona family of Mobile SoCs. FIFO hardware is utilized but only standard mode (100kHz), fast mode (400kHz), fast mode plus (1MHz), and I2C high-speed (3.4 MHz) bus speeds are supported.

(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.

Superseded by tdfxfb. I2C/DDC support used to live in a separate driver but this caused driver conflicts. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Krzysztof Helt <krzysztof.h1@wp.pl>
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>
2009-09-18i2c: Add driver for SMBus Control Method InterfaceCrane Cai

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: Add support for I2C bus on Freescale CPM1/CPM2 controllersJochen Friedrich
This driver uses the port of 2.4 code from Vitaly Bordug <vitb@kernel.crashing.org> and the actual algorithm used by the i2c driver of the DBox code on cvs.tuxboc.org from Felix Domke (tmbinc@gmx.net) and Gillem (htoa@gmx.net) converted to an of_platform_driver. Tested on CPM1 (MPC823 on dbox2 hardware) and CPM2 (MPC8272).
