Add a binding for the regulator which controls the OTG chargepath switch. The OTG switch gets its power from pm8941_5vs1, and that should be expressed as a usb_otg_in-supply property in the DT node for the charger driver. The regulator name is "otg-vbus". Signed-off-by:

The GPIO charger is using a mix of the legacy GPIO interface and <linux/of_gpio.h> which is not the modern way to use GPIOs. Refactor like this: - Use a GPIO descriptor for the GPIO line used to monitor the charger. - Fetch the descriptor with devm_gpiod_get() as the first method. - If this fails and we are *not* using device tree, then start looking to see if we can use platform data instead. - After looking up and requesting a GPIO number with the legacy API, convert it to a descriptor. This way we can later isolate and drop the legacy code as more platforms move over to using descriptors.

Prior to this commit the code was using 1 notifier_block for all types of charger cable, this is incorrect as the notifier_block becomes part of a linked-list and now the same notifier_block is part of 3 linked lists. This commit fixes this by using a separate nb per extcon cable. Note this happened to work fine sofar because axp288_charger was the only listener, so when added to each of the 3 notifier chains, the next pointer in the nb would be set to 0, so we've 3 heads pointing to the same nb, with its next pointing to NULL. But as soon as we mix in a second extcon consumer things will go boom. Signed-off-by:

Deal with the charger type changing without a vbus-disconnect being reported in between the 2 charger type states: -Do not return from axp288_charger_extcon_evt_worker early in this case (track old_chg_type) -Make calling axp288_charger_enable_charger with the same value as before a nop, to avoid the need for the caller to check this -Do no do a dev_err when axp288_charger_enable_charger returns an error, axp288_charger_enable_charger already returns an error itself -Disable the charger before changing the charge-current setting (nop if vbus was seen as disconnected before the change) Signed-off-by:

Nothing was setting info->otg.cable, so the extcon_get_cable_state_ calls on it would always return -EINVAL. This commit fixes this by actually setting info->otg.cable using the new extcon_get_extcon_dev_by_cable_id function. This commit also makes failing to register the extcon notifier for the USB_HOST cable an error rather then a warning, because we MUST have this notfier to properly disable the VBUS path when in host mode so that we're not drawing current from the 5V boost converter which is supplying power to the otg port when in host mode.

Use devm_power_supply_register instead of power_supply_register, this avoids the need to do manual cleanup and results in quite a nice code cleanup.

During probe, it makes no sense to take care to first not issue any i2c commands to verify if the connected part really is a bq24735, to later simply fail the probe in the next step when trying to configure the charger. So, delay configuration of the charging parameters until the charger is accessible (i.e. when the AC adapter is present) as part of enabling the charging. This also fixes the rather serious issue that the charging parameters are lost when the AC adapter is disconnected. Signed-off-by:
