You can do that with the current i2c drivers by making sure that adrlen=0. > Will it be acceptable for the community to add those two new interfaces > (i2c_write_direct/i2c_read_direct) for each i2c driver ? I would think they are unneeded, see the adrlen=0 trick. (If I were to suggest an I2C overhaul [hi Heiko :)], I'd rather suggest adding a generic i2c transaction API which would allow mixing elementary writes and reads with optional STARTs and STOPs inbetween). > - Is there any coding style specification ?
