The Point of View protab2-ips9 is a tablet with a 9" ips

What is connected on i2c1 ? Just the camera sensor? or it has

The bma250 accelerometer sits there, and the kernel already has a
driver
for it. That driver needs to have devicetree binding support
added,
and
then we should be able to use the accelerometer.
bma250 already has devicetree support. It is used in Gemei G9
tablet
(sun4i-gemei-g9.dts).
Yes I've seen that, but does it actually work? I've not tried but I
do not see any compatible string in the actual bma250 code in the
kernel,
so I believe that this part of the sun4i-gemei-g9.dts file does not
work ?
It worked (even without IRQs) when I submitted the patch. Driver itself
is under iio/accel/bma180.c
That is really weird, because:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/drivers/iio/accel/bma180.c
Does not have an of_match_table ... ??
