May I need to submit this patch as a series? One patch for one board, 
and cover i2c-gpio and i2c-at91 cases.
e.g:
[patch 1/x] i2c: change id to let i2c-gpio work on at91rm200ek
[patch 2/x] i2c: change id to let i2c-gpio work on at91sam9261ek
...

or

Just one patch, cover all these boards and i2c-gpio and i2c-at91?
