dt-bindings: mfd: Convert pm8xxx bindings to yaml
Convert pm8xxx bindings from .txt to .yaml format. Also, split this binding into two: parent binding(qcom-pm8xxx.yaml) and child node RTC binding(qcom-pm8xxx-rtc.yaml).

Qualcomm PM8xxx PMIC multi-function devices
|
||||
|
||||
The PM8xxx family of Power Management ICs are used to provide regulated
|
||||
voltages and other various functionality to Qualcomm SoCs.

- compatible:
|
||||
Usage: required
|
||||
Value type: <string>
|
||||
Definition: must be one of:
|

"qcom,pm8058"

Usage: required
|

Value type: <u32>
|

- #size-cells:
|
||||
Usage: required
|
||||
Value type: <u32>
|
||||
Definition: must be 0
|
||||
|
||||
- interrupts:
|
||||
Usage: required
|
||||
Value type: <prop-encoded-array>
|
||||
Definition: specifies the interrupt that indicates a subdevice
|
||||
has generated an interrupt (summary interrupt). The
|
||||
format of the specifier is defined by the binding document
|
||||
describing the node's interrupt parent.
|
||||
|
||||
- #interrupt-cells:
|
||||
Usage: required
|
||||
Value type : <u32>
|
||||
Definition: must be 2. Specifies the number of cells needed to encode
|
||||
an interrupt source. The 1st cell contains the interrupt
|
||||
number. The 2nd cell is the trigger type and level flags
|
||||
encoded as follows:
|
||||
|
||||
1 = low-to-high edge triggered
|
||||
2 = high-to-low edge triggered
|
||||
4 = active high level-sensitive
|
||||
8 = active low level-sensitive
|
||||
|
||||
- interrupt-controller:
|
||||
Usage: required
|
||||
Value type: <empty>
|
||||
Definition: identifies this node as an interrupt controller
|
||||
|
||||
= SUBCOMPONENTS
|
||||
|
||||
The PMIC contains multiple independent functions, each described in a subnode.
|
||||
The below bindings specify the set of valid subnodes.

Value type: <prop-encoded-array>

Usage: required

Value type: <prop-encoded-array>

- allow-set-time:
|

Usage: optional
|

Value type: <empty>
|

Definition: indicates that the setting of RTC time is allowed by
