+
+description: |
+ The devicetree battery node provides static battery characteristics.
+ In smart batteries, these are typically stored in non-volatile memory
+ on a fuel gauge chip. The battery node should be used where there is
+ no appropriate non-volatile memory, or it is unprogrammed/incorrect.
+
+ Upstream dts files should not include battery nodes, unless the battery
+ represented cannot easily be replaced in the system by one of a
+ different type. This prevents unpredictable, potentially harmful,
+ behavior should a replacement that changes the battery type occur
+ without a corresponding update to the dtb.
+
+ Battery properties are named, where possible, for the corresponding elements
+ in enum power_supply_property, defined in include/linux/power_supply.h
+
+ Batteries must be referenced by chargers and/or fuel-gauges using a phandle.
+ The phandle's property should be named "monitored-battery".

+ Specify what irqs are needed to be handled by MT6370 Charger driver.
+ We need to use the IRQ "MT6370_IRQ_OVPCTRL_UVP_D" to know when USB
+ is plugged in, and then the driver will enable BC1.2 detection.
+ After the hardware of MT6370 completes the BC1.2 detection,
+ IRQ "MT6370_IRQ_ATTACH" will be triggered, and the driver will know
+ the result of BC1.2 detection.
+ When the IRQ "MT6370_IRQ_CHG_MIVR" is triggered, it means that the
+ hardware enters the "Minimum Input Voltage Regulation loop" and
+ a workaround needs to be applied at this time.
+ In summary, "MT6370_IRQ_OVPCTRL_UVP_D", "MT6370_IRQ_ATTACH" and
+ "MT6370_IRQ_CHG_MIVR" are required in this charger driver.

+description: |
+ Samsung SDI (Samsung Digital Interface) batteries are all different versions
+ of lithium ion chemistry devices used for mobile phones, laptops and other
+ portable electronics. The batteries are adapted to a specific product and
+ the physical restrictions make it impossible to use another battery with the
+ product, so product device trees can specify these batteries. Operating
+ systems should determine hardware characteristics of the batteries from the
+ compatible string.

+ The choice of phy cannot be configured at a hardware level, so there is no
