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
|
|
TPS80036 supports the backup battery for powering the RTC when main
|
|
battery is removed or in very low power state. The backup battery
|
|
can be chargeable or non-chargeable. This flag will tells whether
|
|
battery is chargeable or not. If charging battery then driver can
|
|
enable the charging.
|
|
- ti,backup-battery-charge-high-current: Enable high current charging in
|
|
backup battery. Device supports the < 100uA and > 100uA charging.
|
|
The high current will be > 100uA. Absence of this property will
|
|
charge battery to lower current i.e. < 100uA.
|
|
|
|
Example:
|
|
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;
|
|
};
|
|
...
|
|
};
