This patch series is to improve the implementation of act8945a-charger
driver, such as regard the act8945-charger as a sub-device, improve
the way to check the status, fix the power supply type property,
add the status change update, and add more properties: capacity level
property and max current property.

Changes in v9:
 - For "lbo-gpios", use devm_gpiod_get_optional(), instead of
   devm_gpiod_get(), for simpler and more reasonable.
 - Remove unnecessary GPIOLIB dependency.
 - For "chglev-gpios", use devm_gpiod_get_optional(), instead of
   devm_gpiod_get(), for simper and more reasonable.
 - Not include seven patches which have been queued or applied.

Changes in v8:
 - As the act8945a_charger is regarded as a sub-device, all
   properties can be achieved from its own device node,
   use devm_gpiod_get() properly as well to get "lbo-gpios".
 - Add missing return -EPROBE_DEFER  for "lbo-gpios".
 - As the act8945a_charger is regarded as a sub-device, all
   properties can be achieved from its own device node,
   use devm_gpiod_get() properly as well to get "chglev-gpios".
 - Add missing return -EPROBE_DEFER  for "chglev-gpios".
 - Add 4 new patches: 1/11, 2/11, 9/11, and 11/11.

Changes in v7:
 - For "lbo-gpios", use gpiod_get() to fix devm_gpiod_get() wrong use
   with parent device as *dev argument.
 - Add the handle -EPROBE_DEFER returned from gpiod_get "lbo-gpios".
 - Use dev_info() to print log if the lbo irq request failed.
 - Remove unneeded semicolon.
 - Add depends on GPIOLIB for use gpiod.
 - For "chglev-gpios", use gpiod_get() to fix devm_gpiod_get() wrong use
   with parent device as *dev argument.
 - Add the handle -EPROBE_DEFER returned from gpiod_get "chglev-gpio".
 - Remove unneeded semicolon.

Changes in v6:
 - For "lbo-gpios", use gpiod API instead of old gpio API to handle.
 - For "chglev-gpios", use gpiod API instead of old gpio API to handle.

Changes in v4:
 - Change devname of devm_request_irq() from "lbo-detect" to
   "act8945a, lbo-detect".
 - Fix wrong gpio assignment for chglev_pin.

Add the power supply capacity level property, it corresponds to
POWER_SUPPLY_CAPACITY_LEVEL_*.

It also utilizes the precision voltage detector function module
to catch the low battery voltage.

* [PATCH v9 1/4] power: act8945a_charger: Add capacity level property
@ 2016-09-01  9:29   ` Wenyou Yang

Add the power supply capacity level property, it corresponds to
POWER_SUPPLY_CAPACITY_LEVEL_*.

It also utilizes the precision voltage detector function module
to catch the low battery voltage.

Changes in v9:
 - For "lbo-gpios", use devm_gpiod_get_optional(), instead of
   devm_gpiod_get(), for simpler and more reasonable.
 - Remove unnecessary GPIOLIB dependency.

Changes in v8:
 - As the act8945a_charger is regarded as a sub-device, all
   properties can be achieved from its own device node,
   use devm_gpiod_get() properly as well to get "lbo-gpios".
 - Add missing return -EPROBE_DEFER  for "lbo-gpios".

Changes in v7:
 - For "lbo-gpios", use gpiod_get() to fix devm_gpiod_get() wrong use
   with parent device as *dev argument.
 - Add the handle -EPROBE_DEFER returned from gpiod_get "lbo-gpios".
 - Use dev_info() to print log if the lbo irq request failed.
 - Remove unneeded semicolon.
 - Add depends on GPIOLIB for use gpiod.

Changes in v6:
 - For "lbo-gpios", use gpiod API instead of old gpio API to handle.

Changes in v4:
 - Change devname of devm_request_irq() from "lbo-detect" to
   "act8945a, lbo-detect".
