+description: |
+  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.

-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

-    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.

-    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:

-	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,
-		LEDS_BOOST_FIXED (2) - fixed mode.
-- maxim,boost-mvout : Output voltage of the boost module in millivolts.
-	Valid values: 3300 - 5500, step by 25 (rounded down)
-	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

+
+description:
+  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.

- * AB8500 register access
- * ======================
- *
- * read:
- * # echo BANK  >  <debugfs>/ab8500/register-bank
- * # echo ADDR  >  <debugfs>/ab8500/register-address
- * # cat <debugfs>/ab8500/register-value

- * # echo BANK  >  <debugfs>/ab8500/register-bank
- * # echo ADDR  >  <debugfs>/ab8500/register-address
- * # echo VALUE >  <debugfs>/ab8500/register-value
- *
- * read all registers from a bank:
- * # echo BANK  >  <debugfs>/ab8500/register-bank
- * # cat <debugfs>/ab8500/all-bank-register
- *
- * BANK   target AB8500 register bank
- * ADDR   target AB8500 register address
- * VALUE  decimal or 0x-prefixed hexadecimal
- *
- *
- * User Space notification on AB8500 IRQ
- * =====================================
- *
- * Allows user space entity to be notified when target AB8500 IRQ occurs.
- * When subscribed, a sysfs entry is created in ab8500.i2c platform device.
- * One can pool this file to get target IRQ occurence information.
- *
- * subscribe to an AB8500 IRQ:
- * # echo IRQ  >  <debugfs>/ab8500/irq-subscribe
- *
- * unsubscribe from an AB8500 IRQ:
- * # echo IRQ  >  <debugfs>/ab8500/irq-unsubscribe
- *
- *
- * AB8500 register formated read/write access
- * ==========================================
- *
- * Read:  read data, data>>SHIFT, data&=MASK, output data
- *        [0xABCDEF98] shift=12 mask=0xFFF => 0x00000CDE
- * Write: read data, data &= ~(MASK<<SHIFT), data |= (VALUE<<SHIFT), write data
- *        [0xABCDEF98] shift=12 mask=0xFFF value=0x123 => [0xAB123F98]
- *
- * Usage:
- * # echo "CMD [OPTIONS] BANK ADRESS [VALUE]" > $debugfs/ab8500/hwreg
- *
- * CMD      read      read access
- *          write     write access
- *
- * BANK     target reg bank
- * ADDRESS  target reg address
- * VALUE    (write) value to be updated
- *
- * OPTIONS
- *  -d|-dec            (read) output in decimal
- *  -h|-hexa           (read) output in 0x-hexa (default)
- *  -l|-w|-b           32bit (default), 16bit or 8bit reg access
- *  -m|-mask MASK      0x-hexa mask (default 0xFFFFFFFF)
- *  -s|-shift SHIFT    bit shift value (read:left, write:right)
- *  -o|-offset OFFSET  address offset to add to ADDRESS value
- *
- * Warning: bit shift operation is applied to bit-mask.
- * Warning: bit shift direction depends on read or right command.
