-* AB8500 Multi-Functional Device (MFD)
-
-Required parent device properties:
-- compatible : contains "stericsson,ab8500" or "stericsson,ab8505";
-- interrupts : contains the IRQ line for the AB8500
-- interrupt-controller : describes the AB8500 as an Interrupt Controller (has its own domain)
-- #interrupt-cells : should be 2, for 2-cell format
- - The first cell is the AB8500 local IRQ number
- - The second cell is used to specify optional parameters
- - bits[3:0] trigger type and level flags:
- 1 = low-to-high edge triggered
- 2 = high-to-low edge triggered
- 4 = active high level-sensitive
- 8 = active low level-sensitive
-
-The AB8500 consists of a large and varied group of sub-devices:

-Required child device properties:
-- compatible : "stericsson,ab8500-[bm|btemp|charger|fg|gpadc|gpio|ponkey|
- pwm|regulator|rtc|sysctrl|usb]";
-
- A few child devices require ADC channels from the GPADC node. Those follow the
- standard bindings from
- https://github.com/devicetree-org/dt-schema/blob/master/schemas/iio/iio-consumer.yaml
- and Documentation/devicetree/bindings/iio/adc/adc.yaml
-
- abx500-temp : io-channels "aux1" and "aux2" for measuring external
- temperatures.
- ab8500-fg : io-channel "main_bat_v" for measuring main battery voltage,
- ab8500-btemp : io-channels "btemp_ball" and "bat_ctrl" for measuring the
- battery voltage.
- ab8500-charger : io-channels "main_charger_v", "main_charger_c", "vbus_v",
- "usb_charger_c" for measuring voltage and current of the
- different charging supplies.
-
-Optional child device properties:
-- interrupts : contains the device IRQ(s) using the 2-cell format (see above)
-- interrupt-names : contains names of IRQ resource in the order in which they were
- supplied in the interrupts property
-- <supply_name>-supply : contains a phandle to the regulator supply node in Device Tree
-
-Non-standard child device properties:
- - Audio CODEC:
- - stericsson,amic[1|2]-type-single-ended : Single-ended Analoge Mic (default: differential)
- - stericsson,amic1a-bias-vamic2 : Analoge Mic wishes to use a non-standard Vamic
- - stericsson,amic1b-bias-vamic2 : Analoge Mic wishes to use a non-standard Vamic
- - stericsson,amic2-bias-vamic1 : Analoge Mic wishes to use a non-standard Vamic
- - stericsson,earpeice-cmv : Earpeice voltage (only: 950 | 1100 | 1270 | 1580)
