[libgpiod][PATCH v3 0/4] tools: timeout handling improvements

[Bartosz Golaszewski <brgl@bgdev.pl>]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

Here's an assortment of improvements to parsing and handling of timeouts
in gpio-tools.

I still decided to unify the period parsing between gpioset and gpioget even
if it doesn't make much sense for gpioget to support periods longer than
fractions of a second. Let users decide.

v2 -> v3:
- only initialize the timespec containing the timeout value once before
  entering the for loop

v1 -> v2:
- extend the series with renaming the timeout variable, using ppoll() instead
  of poll() and supporting minutes as time unit
- drop already applied patch

Bartosz Golaszewski (4):
  tools: rename timeout to idle_timeout in gpiomon and gpionotify
  tools: use ppoll() where higher timeout resolution makes sense
  tools: allow longer time periods
  tools: add minutes as a new supported time unit
