In the interest of making long-term branch maintenance incur as little technical debt on us as possible, we should not maintain any files on the branch we are not actually using. This has the added effect of making it extremely clear when merging CLs from the main branch when changes have the possibility to affect us. The follow-on CL adds a convenience script to actually pull updates from the main branch and generate a CL for the update.

- * Power monitoring and management.
- *
- * The overall goal is to gracefully manage the power demand so that
- * the power budgets are met without letting the system fall into
- * power deficit (perhaps causing a brownout).
- *
- * There are 2 power budgets that need to be managed:
- * - overall system power as measured on the main power supply rail.
- * - 5V power delivered to the USB and HDMI ports.
- *
- * The actual system power demand is calculated from the VBUS voltage and
- * the input current (read from a shunt), averaged over 5 readings.
- * The power budget limit is from the charge manager.
- *
- * The 5V power cannot be read directly. Instead, we rely on overcurrent
- * inputs from the USB and HDMI ports to indicate that the port is in use
- * (and drawing maximum power).
- *
- * There are 3 throttles that can be applied (in priority order):
- *
- * - Type A BC1.2 front port restriction (3W)
- * - Type C PD (throttle to 1.5A if sourcing)
- * - Turn on PROCHOT, which immediately throttles the CPU.
- *
- * The first 2 throttles affect both the system power and the 5V rails.
- * The third is a last resort to force an immediate CPU throttle to
- * reduce the overall power use.
- *
- * The strategy is to determine what the state of the throttles should be,
- * and to then turn throttles off or on as needed to match this.
- *
- * This function runs on demand, or every 2 ms when the CPU is up,
- * and continually monitors the power usage, applying the
- * throttles when necessary.
- *
- * All measurements are in milliwatts.
