Hello Michael,
a "How to send patches", Jagan Teki responded to you, so I only comment
your patch ...
Am 17.09.2013 19:29, schrieb Michael Burr:
Zynq PS has two I2C bus masters (called 'I2C0' and 'I2C1'):
Implement 'i2c_set_bus_num' routine to select from these.
Support I2C devices which do not use internal addresses:
Handle case of 'alen == 0' in 'i2c_read', 'i2c_write'.
This supports PCA9548 bus multiplexer on Xilinx ZC702 board.
Tested cases of 'alen == 0' and 'alen == 1' on this board.
Further minor corrections:
Write 'address' register before 'data' register.
Write 'transfer_size' register before 'address' register.

Thanks for your work!
But please use the new i2c multibus/multiadapter framework for adding
multibus support for this driver. Currently 4 i2c drivers are ported
to this new framework, see:
