From: Qiwu Huang <[email protected]>
This patchset aims to provide power supply properties about wireless/wired charging.
"quick_charge_type" reports different types of quick charge based on the charging power;
"tx_adapter" shows" the type of wireless charging adapter;
"signal_strength" shows the coupling level between TX and RX;
"reverse_chg_mode" provides the interface of enabling/disabling wireless reverse charging.
