6= PROPERTIES
7
8- compatible:
9	Usage: required
10	Value type: <string>
11	Definition: must be one of:
12		    "qcom,pm8058"
13		    "qcom,pm8821"
14		    "qcom,pm8921"
15
16- #address-cells:
17	Usage: required
18	Value type: <u32>
19	Definition: must be 1
20
21- #size-cells:
22	Usage: required
23	Value type: <u32>
24	Definition: must be 0
25
26- interrupts:
27	Usage: required
28	Value type: <prop-encoded-array>
29	Definition: specifies the interrupt that indicates a subdevice
30		    has generated an interrupt (summary interrupt). The
31		    format of the specifier is defined by the binding document
32		    describing the node's interrupt parent.
33
34- #interrupt-cells:
35	Usage: required
36	Value type : <u32>
37	Definition: must be 2. Specifies the number of cells needed to encode
38		    an interrupt source. The 1st cell contains the interrupt
39		    number. The 2nd cell is the trigger type and level flags
40		    encoded as follows:
41
42			1 = low-to-high edge triggered
43			2 = high-to-low edge triggered
44			4 = active high level-sensitive
45			8 = active low level-sensitive
46
47- interrupt-controller:
48	Usage: required
49	Value type: <empty>
50	Definition: identifies this node as an interrupt controller
51
52= SUBCOMPONENTS
53
54The PMIC contains multiple independent functions, each described in a subnode.
55The below bindings specify the set of valid subnodes.

58
59- compatible:
60	Usage: required
61	Value type: <string>
62	Definition: must be one of:
63		    "qcom,pm8058-rtc"
64		    "qcom,pm8921-rtc"
65		    "qcom,pm8941-rtc"
66		    "qcom,pm8018-rtc"
67
68- reg:
69	Usage: required
70	Value type: <prop-encoded-array>
71	Definition: single entry specifying the base address of the RTC registers
72
73- interrupts:
74	Usage: required
75	Value type: <prop-encoded-array>
76	Definition: single entry specifying the RTC's alarm interrupt
77
78- allow-set-time:
79	Usage: optional
80	Value type: <empty>
81	Definition: indicates that the setting of RTC time is allowed by
82		    the host CPU
