Describe the properties used for shared boost configuration.
Use subject prefixes matching the subsystem (which you can get for example with `git log --oneline -- DIRECTORY_OR_FILE` on the directory your patch is touching).

External Boost must have GPIO1 as GPIO output. GPIO1 will be set high to enable boost voltage.
Shared boost allows two amplifiers to share a single boost circuit bycommunicating on the MDSYNC bus. The passive amplifier does not controlthe boost and receives data from the active amplifier. GPIO1 should beconfigured for Sync when shared boost is used. Shared boost is notcompatible with External boost. Active amplifier requiresboost-peak-milliamp, boost-ind-nanohenry and boost-cap-microfarad. 0 = Internal Boost 1 = External Boost2 = Reserved
How binding can be reserved? For what and why? Drop. 2 is shared active, 3 is shared passive.
