I am trying to setup lm-sensors for use with the Texas Instruments
TWL4030 Chip (the main processor is a OMAP3503). But I cannot seem to
get it to detect the chip. I have added the hwmon drivers and I am using
up to date MADC drivers that I have backported to kernel 2.6.32 (I am
running Angstrom).
Disclaimer: I don't know a thing about this chip nor its drivers.
There is no detection support for this device in sensors-detect, if
this was your question. I don't think this device can be detected from
user-space.
I am aware that the automatic detect doesn't work, I have read through
the sensors-detect script.
My understanding is that the drivers for the TWL4030 should all get
loaded automatically thanks to module aliases, as long as the TWL4030
itself is properly registered during platform setup. Check in lsmod
whether twl4030-madc and twl4030-madc-hwmon are actually loaded. If
not, try loading them manually
lsmod doesn't show the drivers, but they should have been compiled into
the kernel, not as modules. Maybe
that is the problem?
No, this shouldn't make a difference. Check under /sys/devices/platform
if the platform devices have been properly created
Ok, they are missing from there. I guess there is some problem with
compiling in the drivers then. Is it enough to compile them in or do I
initialize them in the board specific files in any way?

Niclas
