x86-power-control

[Vijay Khemka]

Hi Jason/James,
I see some limitation in current x86-power-control as we don’t have NMI_OUT, NMI_BUTTON and ID_BUTTON usage. And I am not sure why these are being used. So if I don’t define these in DTS then this program fails. So Please how to disable these. These should be optional. I have following options to disable these.

1. No returning -1 if we don't find line name, simply move on. I have to see impact on rest of code.
2. Make it compile time flag and should be included through bbappend like -DNMI_OUT etc.
3. Have config Jason file and enable or disable gpio line to be used.


Please let us know your thought and how should we approach. I am fine with changing this code and submit patch.

Regards
-Vijay
