Can you put this in drivers/ this doesn't looks like it need to be here.Where would you suggest? ?The initial attempt to model SSBI as an I2C bus didn't go anywhere. ?See http://lkml.org/lkml/2010/7/21/400. ?This functionality is specific to MSM. ?Plus, we're trying to maintain similarity to the Android MSM tree. ?That may not matter to people who don't use MSM, but is matters to us. ?Given these considerations, the current location seems as good a place as any.I don't know the driver well enough to be more detailed than suggesting drivers/ . In the thread you quoted Pavel (who I added to the CC line) suggested drivers/ssbi/ .
I'm not sure that knowing the driver would help. SSBI is a Qualcomm proprietary protocol that will only ever have one ssbi "host" driver in it. The slave is always the PMIC (maybe the audio codec too, but that's normally speaking i2c even in qualcomm's case). The slave PMIC drivers, however, will go under drivers/mfd for the core and the peripheral drivers into the appropriate drivers/xxx/ dirs, just like all the other pmic drivers. The audio codec would go into sound/soc/codecs. Thus, adding drivers/ssbi/ to just house ssbi.c doesn't really make sense to me. What is the problem leaving it under arch/arm/mach-msm? --Dima
