Motorola Mobility. sgm4154x_charger_lite Specific Bindings
|
||||
|
||||
This sgm4154x charger driver is a lite version to support battery
|
||||
charging without BC1.2 charger type detection over DP/DM or OTG
|
||||
function.
|
||||
It utilizes an external USB power supply to query the input status
|
||||
and charger type.
|
||||
|
||||
This charger driver can work independently or cooperate with Motorola
|
||||
mmi_charger under the new Motorola charger driver architecture, so as
|
||||
to support multiple batteries system design.

- mmi,mmi-temp-zones
|
||||
Usage: optional
|
||||
Value Type: Array of tuples of <u32>
|
||||
Definition: Unlimited array of arrays. Each internal array needs to have a set
|
||||
of 4 bytes, each one representing this sequence: Temperature (in degC), Step
|
||||
"Normalized" Voltage (in millivolts), Full Rate "FCC" Current (in milliamps),
|
||||
and Taper Rate "FCC Normalized" Current (in milliamps). These values are
|
||||
related to charging limitations based on temperature specifications. Note that
|
||||
setting a voltage to '0' means that it doesn't matter the battery voltage on
|
||||
that defined temperature range to perform necessary tapering. To understand how
|
||||
Those values are used, please check the "IEEE Charging Compliance" section below.
|
||||
In order to support charging current limit based on battery voltage in the same
|
||||
temperature zone, one zone allows to have multiple lines with ascending sequence
|
||||
by float voltage. First find the temperature zone, and then find the right one
|
||||
among the same zone according to current battery voltage.
|
||||
|
||||

|
||||
Value Type: <u32>
|
||||

|
||||
current becomes below this value, it indicates FULL charging. If not defined,
|
||||
defaults to 300.

||||
|

|
||||
Usage: optional
|
||||

|
||||
|
||||
- mmi,vfloat-comp-uv
|
||||
Usage: optional
|
||||
Value Type: <u32>
|
||||
Definition: This is a tolerance, in uV, for battery floating voltage when
|
||||
charging is being limited. Such situation can happen when either battery is
|
||||
close to full or when there's thermal mitigation on charging. If not set,
|
||||
defaults to 0.
|
||||
|
||||
- mmi,max-fv-mv
|
||||
Usage: optional
|
||||
Value Type: <u32>
|
||||
Definition: It will define the maximum battery charging voltage (in milliamps).
|
||||
This value is used as the max float voltage for battery charging. If not
|
||||

||||
|
||||

|
||||
Usage: optional
|
||||
Value Type: <u32>
|
||||
Definition: It will define the maximum battery charging voltage (in milliamps)
|
||||
in demo mode. This value is used as the max float voltage for battery charging in
|
||||
demo mode. If not defined, defaults to 4000.

||||
|
||||
- mmi,mmi-ffc-zones
|
||||
Usage: optional
|
||||
Value Type: Array of tuples of <u32>
|
||||
Definition: Unlimited array of arrays. Each internal array needs to have a set
|
||||
of 4 data members, each one representing this sequence: Temperature (in degC),
|
||||
maximum Float Voltage (in millivolts), charging terminated current(in milliamps),
|
||||
and Fuel Gauge FULL terminated current (in milliamps). These values are
|
||||

|
||||
battery supports Flash Fast Charging.
