This patch series fixes support for using a GPIO line as an analog input to
the ADC on the LTC4245 chip. Jean suggested dropping support for multiple
GPIO lines, and then adding it back as an optional feature.
I think this is fairly unintrusive to the ltc4245 code, and the multi-GPIO
support is well encapsulated in a seperate function, hidden behind a kernel
configuration option.
I have tested the sensors utility with the -EAGAIN code for stale values.
The output looks like this:
ltc4245-i2c-1-22
12V Input: +11.66 V
5.0V Input: +5.10 V
3.3V Input: +3.19 V
VEE Input: +0.00 V
12V Output: +11.66 V
5.0V Output: +5.08 V
3.3V Output: +3.19 V
VEE Output: +0.00 V
Dig 3.30v Output: +3.26 V
ERROR: Can't get value of subfeature in10_input: Can't read
Dig 2.25v Output: +0.00 V
ERROR: Can't get value of subfeature in11_input: Can't read
Dig 1.80v Output: +0.00 V
12V Power: 816.20 mW
5.0V Power: 4.90 W
3.3V Power: 1.44 W
VEE Power: 0.00 nW
12V Current: +0.07 A
5.0V Current: +0.96 A
3.3V Current: +0.45 A
VEE Current: +0.00 A
Using cat to read the inX_input nodes, I get the expected output:
cat: in9_input: Resource temporarily unavailable
So I think that the lm-sensors software will handle this method of showing
stale values just fine.
Thanks,
Ira

Whoops, I just noticed that this is the wrong patch series. I'll send
the correct series immediately.
Please ignore it. Sorry for the noise.
