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.
Changes in v6
- Replace "phones" with "devices" suggested by GregKH
- Add permission statement for "reverse_chg_mode"
- Update description for "reverse_chg_mode" in ABI suggested by GregKH
- Update description for "PING phase" in ABI suggested by GregKH
Changes in v5
- Add details in 0/X email
Changes in v4
- Exclude the patch of "power: supply: supply battery soc with decimal form"
- Fix some typo
Changes in v3
- Add enumederated for quick charge type
- Add enumederated for tx adapter type
- Update the return type and description in ABI
Changes in v2
- modify to capital letters for "power_supply_attrs"
- Update the return type and description in ABI
