This binding can support Ingenic JZ4725B and JZ4770 SoCs, as they are compatible with Ingenic JZ4740 battery. Introduce the following compatible property combinations: compatible = "ingenic,jz4725b-battery", "ingenic,jz4740-battery", compatible = "ingenic,jz4770-battery", "ingenic,jz4740-battery" Signed-off-by:

The bindings for charger-manager were very unclear and didn't specify allowable values in many cases. Clean these up to show what each value does and make sure all properties are documented here rather than using wildcards. Signed-off-by:

In commit 830ae442 ("extcon: Remove the deprecated extcon functions") the function extcon_register_interest became a no-op returning an error, leading to non-functional behaviour in charger-manager. Additionally, a translation table is needed between the text representation of the extcon cable names and their IDs is needed. In order to retain DT compatibility, TA and CHARGE-DOWNSTREAM are added as they were present up until commit 11eecf91 ("extcon: Modify the id and name of external connector") Signed-off-by:

Prevents direct charging control in cable notification and only set the input current limit according to cable type. Leave the enabling of charing to cm_monitor() where charging management proceeds. We may lose a few ms to enable charging compared to before, but it's more important that charging is enabled always in safe context. Signed-off-by:

cm_monitor(), where charging management starts, checks various charging condition sequentially to decide next charging operation. However, as it follows sequential process, cascaded if statements, it does some jobs which have already done in the previous stage. This results in a delay in decision making. Moreover, starting point of charging is spread all around which makes maintain code and debugging difficult. Both of the problems mentioned above become clean if it manages battery charging focusing on battery status not following sequential condition checking. Now, cm_monitor() moves battery state diagram and does the optimal operation for current state. As a result, it reduces whole monitoring time almost in half. Signed-off-by:

We were using POWER_SUPPLY_PROP_TEMP if the temperature was coming via the fuel gauge and POWER_SUPPLY_PROP_TEMP_AMBIENT if it was coming via the thermal framework. Since they're mutually exclusive in the driver and we don't know if the thermal framework is ambient or not, unify them both to use POWER_SUPPLY_PROP_TEMP. Signed-off-by:

cm_notify_event() was introduced to get an event associated with the battery status externally (ie in board files), but no one ever used it. Moreover it makes charger manager driver more complicated. Drop the function and all data related to it to simplify the driver. Signed-off-by:

Whenever the battery status is changed, charger manager triggers a uevent through a private interface. Modify it to use power_supply_changed() since it belongs to the power supply subsystem. Signed-off-by:

Both chips have charger and a fuel gauge. This adds basic support for displaying the state of the battery and the input power, settings are not modified. There are some defaults set via OTP. Charging also starts after plugging USB. Known issues of the fuel gauge: There are drivers in the wild which disable the fuel gauge at shutdown. If a kernel is booted without fuel gauge support, after such a driver has been used, the fuel gauge will stay off and decalibrate. If this driver is used after that, it might display wrong values for charge level. Signed-off-by:

Current sbs-battery considers all smbus errors as disconnection events when battery-detect pin isn't supplied, and restored to present state back when any successful transaction is made. This can lead to unwanted state changes between present and !present when there's one i2c error and other following commands were successful. This patch provides a unified way of checking presence by calling sbs_get_battery_presence_and_health() when detect pin is not used. Signed-off-by:

SMB347 is a charger and not a battery driver. Secondly, power-supply core now supports monitored-battery. So the 'fake' battery doesn't do anything useful for us, and thus, it should be removed. Transfer smb347-battery functionality into smb347-mains and smb347-usb. Reviewed-by:

This patch adds device-tree support to the SMB347 charger driver. All legacy platform data now can be parsed from DT. Because of that and since SMB347 is an I2C client driver, the IRQ number can be passed automatically through client's IRQ variable if it's defined in DT. There is no need to map GPIO to IRQ manually in the case of DT.
