+Description:
+ In PING phase, RX transmits a signal strength packet as the
+ first communication packet to instruct the base to keep power
+ signal on.The value reports wireless signal strength and show
+ degree of coupling.
+
+ The Qi Wireless Power Transfer System is published by the
+ Wireless Power Consortium.The ping phase is the necessary stage
+ for matching transmitter and receiver. In this phase,the Power
+ Transmitter executes a Digital Ping, and listens for a response.
+ If the Power Transmitter discovers a Power Receiver, the Power
+ Transmitter may extend the Digital Ping,i.e. maintain the Power
+ Signal at the level of the Digital Ping. This causes the system
+ to proceed to the identification & configuration phase. If the
+ Power Transmitter does not extend the Digital Ping, the system
+ shall revert to the selection phase.

[PATCH v8 0/4] add some power supply properties about wireless/wired charging
From: Qiwu Huang 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 v8 - Add quick charge type driver in qcom_smbb suggested by GregKH Changes in v7 - Fix PATCH version error in 0/X email 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 Qiwu Huang (4): power: supply: core: add quick charge type property power: supply: core: add wireless charger adapter type property power: supply: core: add wireless signal strength property power: supply: core: property to control reverse charge Documentation/ABI/testing/sysfs-class-power | 85 + drivers/power/supply/power_supply_sysfs.c | 4 + drivers/power/supply/qcom_smbb.c| 51 + include/linux/power_supply.h| 35 + 4 files changed, 175 insertions(+) -- 2.28.0

+Description:
+ In PING phase, RX transmits a signal strength packet as the

+ signal on.The value reports wireless signal strength and show
+ degree of coupling.
+
+ The Qi Wireless Power Transfer System is published by the
+ Wireless Power Consortium.The ping phase is the necessary stage
+ for matching transmitter and receiver. In this phase,the Power
+ Transmitter executes a Digital Ping, and listens for a response.
+ If the Power Transmitter discovers a Power Receiver, the Power
+ Transmitter may extend the Digital Ping,i.e. maintain the Power
+ Signal at the level of the Digital Ping. This causes the system
+ to proceed to the identification & configuration phase. If the
+ Power Transmitter does not extend the Digital Ping, the system
+ shall revert to the selection phase.

+ If the Power Transmitter discovers a Power Receiver, the Power
+ Transmitter may extend the Digital Ping,i.e. maintain the Power
