* i2c: robotfuzz-osif: drop pointless testPeter Rosin2018-05-241-2/+2
| | | | | | | | | In the for-loop test, ret will be either 0 or 1. So, the comparison is pointless. Drop it, and drop the initializer which is then also pointless. Signed-off-by: Peter Rosin <peda@axentia.se> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
* i2c: robotfuzz-osif: remove pointless local variablePeter Rosin2018-05-241-10/+7
| | | | | | | | Just use the value directly instead of assigning it to a variable first. And then drop the unused variable. Signed-off-by: Peter Rosin <peda@axentia.se> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
* i2c: busses: constify i2c_algorithm structuresBhumika Goyal2017-02-091-1/+1
| | | | | | | | | | | | | | Declare i2c_algorithm structures as const as they are only stored in the algo field of an i2c_adapter structure. This field is of type const, so i2c_algorithm structures having this property can be made const too.

* i2c: Add bus driver for for OSIF USB i2c device.Andrew Lunn2014-01-131-0/+202
OSIF, Open Source InterFace, is a USB based i2c bus master. The origional design was based on i2c-tiny-usb, but more modern versions of the firmware running on the MegaAVR microcontroller use a different protocol over the USB. This code is based on Barry Carter <barry.carter@gmail.com> driver. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
