[v2,0/2] Add GPIO brownout detection support

Message

Hi,

this is my v2 of my v1 [1]. I converted the driver from the input to the
hwmon framework, as proposed by Trent [2]. Futhermore I droped the OF
dependency for the core functionality (sensing the gpio) and moved the
addtional feature (unbinding devices) to a additional config. So the
dependencies are much cleaner.

The spi patches are already applied by Mark so I dropped them in my v2.
You have to apply the patche from Marks Git:

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git tags/spi-find-by-node

to get the patch stack compiled.

I rebased the series on top of Guenter's hwmon-next branch and checked
it by checkpatch. Unfortunately it complains about a missing help
paragraph for SENSORS_GPIO_BROWNOUT_UNBIND, but the help exists.

Regards,
Marco
