i2c_new_device() with lis3lv02d for i801 i2c bus needs to be called
after initializing i2c-i801 bus driver.
I have no idea how to do it (properly) outside of i2c-i801.c file.
I once used bus_notifiers to achieve something similar. You could check
arch/arm/mach-shmobile/regulator-quirk-rcar-gen2.c to see an action
triggered once a client device got added, but you could act on another
action like BUS_NOTIFY_BOUND_DRIVER. I used exactly that, too, somewhen
somewhere. Haven't checked if that helps here, too. And since we have
a
precedence (Fujitsu case), I'll leave it to Jean who is the maintainer
of this driver.
Thanks,
Wolfram
