i2c: i2c-ocores: support for 16bit and 32bit IO

2012-07-14T11:30:25+00:00

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 property

2012-07-14T11:30:24+00:00

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. Signed-off-by: Ganesan Ramalingam Signed-off-by: Jayachandran C Signed-off-by: Wolfram Sang

i2c-ocores: Can add I2C devices to the bus

2009-06-13T09:39:28+00:00

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. Signed-off-by: Richard Röjfors Signed-off-by: Ben Dooks
