This is a part of device tree bindings for Maxim MAX77693 MicroUSB Integrated
|
||||
Circuit (MUIC).
|
||||
|
||||
There are two LED outputs available - FLED1 and FLED2. Each of them can
|
||||
control a separate LED or they can be connected together to double the
|
||||
maximum current for a single connected LED. One LED is represented by one
|
||||
child node.
|
||||
|
||||
See also Documentation/devicetree/bindings/mfd/maxim,max77693.yaml for
|
||||
additional information and example.

not enabled explicitly, boost setting defaults to LEDS_BOOST_FIXED in

case both current sources are used.

Maxim MAX77693 multi-function device
|
||||
|
||||
MAX77693 is a Multifunction device with the following submodules:
|
||||
- PMIC,
|
||||
- CHARGER,
|
||||
- LED,
|
||||
- MUIC,
|
||||
- HAPTIC
|
||||
|
||||
It is interfaced to host controller using i2c.
|
||||
This document describes the bindings for the mfd device.
|
||||
|
||||
Required properties:
|
||||
- compatible : Must be "maxim,max77693".
|
||||
- reg : Specifies the i2c slave address of PMIC block.
|
||||
- interrupts : This i2c device has an IRQ line connected to the main SoC.
|
||||
|
||||
Optional properties:
|
||||
- regulators : The regulators of max77693 have to be instantiated under subnode
|
||||
named "regulators" using the following format.
|
||||
|
||||
regulators {
|
||||
regulator-compatible = ESAFEOUT1/ESAFEOUT2/CHARGER
|
||||
standard regulator constraints[*].
|
||||
};
|
||||
|
||||
[*] refer Documentation/devicetree/bindings/regulator/regulator.txt
|
||||
|
||||
- haptic : The MAX77693 haptic device utilises a PWM controlled motor to provide
|
||||
users with tactile feedback. PWM period and duty-cycle are varied in
|
||||
order to provide the appropriate level of feedback.
|
||||
|
||||
Required properties:
|
||||
- compatible : Must be "maxim,max77693-haptic"
|
||||
- haptic-supply : power supply for the haptic motor
|
||||
[*] refer Documentation/devicetree/bindings/regulator/regulator.txt
|
||||
- pwms : phandle to the physical PWM(Pulse Width Modulation) device.
|
||||
PWM properties should be named "pwms". And number of cell is different
|
||||
for each pwm device.
|
||||
To get more information, please refer to documentation.
|
||||
[*] refer Documentation/devicetree/bindings/pwm/pwm.txt
|
||||
|
||||
- charger : Node configuring the charger driver.
|
||||
If present, required properties:
|
||||
- compatible : Must be "maxim,max77693-charger".
|
||||
|
||||
Optional properties (if not set, defaults will be used):
|
||||
- maxim,constant-microvolt : Battery constant voltage in uV. The charger
|
||||
will operate in fast charge constant current mode till battery voltage
|
||||
reaches this level. Then the charger will switch to fast charge constant
|
||||
voltage mode. Also vsys (system voltage) will be set to this value when
|
||||
DC power is supplied but charger is not enabled.
|
||||
Valid values: 3650000 - 4400000, step by 25000 (rounded down)
|
||||
Default: 4200000
|
||||
|
||||
- maxim,min-system-microvolt : Minimal system voltage in uV.
|
||||
Valid values: 3000000 - 3700000, step by 100000 (rounded down)
|
||||
Default: 3600000
|
||||
|
||||
- maxim,thermal-regulation-celsius : Temperature in Celsius for entering
|
||||
high temperature charging mode. If die temperature exceeds this value
|
||||
the charging current will be reduced by 105 mA/Celsius.
|
||||
Valid values: 70, 85, 100, 115
|
||||
Default: 100
|
||||
|
||||
- maxim,battery-overcurrent-microamp : Overcurrent protection threshold
|
||||
in uA (current from battery to system).
|
||||
Valid values: 2000000 - 3500000, step by 250000 (rounded down)
|
||||
Default: 3500000
|
||||
|
||||
- maxim,charge-input-threshold-microvolt : Threshold voltage in uV for
|
||||
triggering input voltage regulation loop. If input voltage decreases
|
||||
below this value, the input current will be reduced to reach the
|
||||
threshold voltage.
|
||||
Valid values: 4300000, 4700000, 4800000, 4900000
|
||||
Default: 4300000
|
||||
|
||||
- led : the LED submodule device node
|
||||
|
||||
There are two LED outputs available - FLED1 and FLED2. Each of them can
|
||||
control a separate LED or they can be connected together to double
|
||||
the maximum current for a single connected LED. One LED is represented
|
||||
by one child node.
|
||||
|
||||
Required properties:
|
||||
- compatible : Must be "maxim,max77693-led".
|
||||
|
||||
Optional properties:
|
||||
- maxim,boost-mode :
|
||||
In boost mode the device can produce up to 1.2A of total current
|
||||
on both outputs. The maximum current on each output is reduced
|
||||
to 625mA then. If not enabled explicitly, boost setting defaults to
|
||||
LEDS_BOOST_FIXED in case both current sources are used.
|
||||
Possible values:
|
||||
LEDS_BOOST_OFF (0) - no boost,
|
||||
LEDS_BOOST_ADAPTIVE (1) - adaptive mode,
|
||||

|
||||
Default: 3300
|
||||
- maxim,mvsys-min : Low input voltage level in millivolts. Flash is not fired
|
||||
if chip estimates that system voltage could drop below this level due
|
||||
to flash power consumption.
|
||||
Valid values: 2400 - 3400, step by 33 (rounded down)
|
||||
Default: 2400
|
||||
|
||||

|
||||
15625 - 500000, step by 15625 (rounded down)
|
||||
- flash-max-microamp : see Documentation/devicetree/bindings/leds/common.txt
|
||||
Valid values for a single LED connected to one FLED output
|
||||
(boost mode must be turned off):
|
||||
15625 - 1000000, step by 15625 (rounded down)
|
||||
Valid values for a single LED connected to both FLED outputs:
|
||||
15625 - 1250000, step by 15625 (rounded down)
|
||||

Required properties:
|
||||
|
||||
- compatible : "samsung,exynos5433-lpass"
|
||||
- reg : should contain the LPASS top SFR region location
|
||||
and size
|
||||
- clock-names : should contain following required clocks: "sfr0_ctrl"
|
||||
- clocks : should contain clock specifiers of all clocks, which
|
||||
input names have been specified in clock-names
|
||||
property, in same order.
|
||||
- #address-cells : should be 1
|
||||
- #size-cells : should be 1
|
||||
- ranges : must be present
|
||||
|
||||
Each IP block of the Low Power Audio Subsystem should be specified as
|
||||
an optional sub-node. For "samsung,exynos5433-lpass" compatible this includes:
|
||||
UART, SLIMBUS, PCM, I2S, DMAC, Timers 0...4, VIC, WDT 0...1 devices.
|

|

the AB8500 "Analog Baseband" is the mixed-signals integrated circuit
|
||||
handling power management (regulators), analog-to-digital conversion
|
||||
(ADC), battery charging, fuel gauging of the battery, battery-backed
|
||||
RTC, PWM, USB PHY and some GPIO lines in the ST-Ericsson U8500 platforms
|
||||
in connection with the DB8500 digital baseband. The DB8500 PRCMU
|
||||
communicates directly and autonomously with the AB8500 and thus it
|
||||
appears as a subnode of the DB8500 PRCMU. An altered version called
|
||||
AB8505 also exist, the difference in AB8505 is that some of the USB and
|
||||
USB charging handling has changed, and it has an embedded USB-to-serial
|
||||
converter. Most subblocks takes their interrupts directly from the
|
||||
AB8500 embedded interrupt controller.
