This allows using OpenCores I2C controller attached to its host in
native-endian mode with bi-endian CPUs. Example of such system is Xtensa
XTFPGA platform.

i2c: i2c-ocores: support for 16bit and 32bit IO2012-07-14T11:30:25ZGanesan Ramalingamganesanr@broadcom.com2012-07-13T13:44:25Zurn:sha1:7326e38ffe894d0cd2904704b7d8c53d4a55d752
Some architectures supports only 16-bit or 32-bit read/write access to
their IO space. Add a 'reg-io-width' platform and OF parameter which
specifies the IO width to support these platforms.
reg-io-width can be specified as 1, 2 or 4, and has a default value
of 1 if it is unspecified.

i2c: i2c-ocores: Use reg-shift property2012-07-14T11:30:24ZGanesan Ramalingamganesanr@broadcom.com2012-07-13T13:44:23Zurn:sha1:8bb986a816148d6e8fbaae23be0fee33d6a1ae3f
Deprecate 'regstep' property and use the standard 'reg-shift' property
for register offset shifts. 'regstep' will still be supported as an
optional property, but will give a warning when used.

i2c-ocores: Can add I2C devices to the bus2009-06-13T09:39:28ZRichard Röjforsrichard.rojfors.ext@mocean-labs.com2009-06-05T13:40:32Zurn:sha1:dd14be4c274fc484eccace03ae9726e516630331
There is sometimes a need for the ocores driver to add devices to the
bus when installed.
i2c_register_board_info can not always be used, because the I2C devices
are not known at an early state, they could for instance be connected
on a I2C bus on a PCI device which has the Open Cores IP.
i2c_new_device can not be used in all cases either since the resulting
bus nummer might be unknown.
The solution is the pass a list of I2C devices in the platform data to
the Open Cores driver. This is useful for MFD drivers.

[PATCH] i2c: New bus driver for the OpenCores I2C controller2006-06-22T18:10:33ZPeter Korsgaardjacmet@sunsite.dk2006-06-04T18:01:08Zurn:sha1:18f98b1e3147afdb51e545cc6ff2b016c7d088a7
The following patch adds support for the OpenCores I2C controller IP
core (See http://www.opencores.org/projects.cgi/web/i2c/overview).
