Palmas RTC controller bindings

|
Required properties:
|
|
- compatible:
|
|
- "ti,palmas-rtc" for palma series of the RTC controller
|
|
- interrupt-parent: Parent interrupt device, must be handle of palmas node.
|
|
- interrupts: Interrupt number of RTC submodule on device.
|
|
|
|
Optional properties:
|
|
|
|
- ti,backup-battery-chargeable: The Palmas series device like TPS65913 or
|

|
|
backup battery. Device supports the < 100mA and > 100mA charging.

|
The high current will be > 100mA. Absence of this property will
|
|
charge battery to lower current i.e. < 100mA.
|

|
|
palmas: tps65913@58 {
|
|
...
|
|
palmas_rtc: rtc {
|
|
compatible = "ti,palmas-rtc";
|
|
interrupt-parent = <&palmas>;
|
|
interrupts = <8 0>;
|
|
ti,backup-battery-chargeable;
|

ti,backup-battery-charge-high-current;
|
|
