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.
