Subject: tools: add ledumon and ledhwbmon packages
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=aab21ee0552019c4bf1c7b829aea2992b59fb9bf;p=openwrt%2Fstaging%2Fxback.git

tools: add ledumon and ledhwbmon packages

ledumon:
This program creates a new userspace LED class device and monitors it.
For this it es using the kmod-leds-uled.ko kernel module.

ledhwbmon:
This program monitors LED brightness level changes having its origin
in hardware/firmware, i.e. outside of kernel control.
