There is a 4% difference between the kernel's view of battery level and the actual battery level, to give userspace a chance to shut down cleanly. The EC should turn the lightbar red when the battery drops below 10%, so this change makes that happen when the kernel says it's 10%, instead of the real 10%. Note: We don't have to cherry-pick this to the Link branch. Although it affects the EC, we already patch the EC lightbar parameters at boot and that's done in userspace. BUG=chromium:225500 BRANCH=none TEST=manual Unplug Link, let the battery run down. The lightbar should pulse red when the battery level reported by the UI drops to 9% (there may be a little delay due to rounding). Note that it's only red when on battery.

Sometimes we need to perform some run-time tweaks of the EC from the AP's userspace. This directory holds those tweaks. They're picked up by the ec-utils ebuild.
