1Palmas RTC controller bindings 2 3Required properties: 4- compatible: 5 - "ti,palmas-rtc" for palma series of the RTC controller 6- interrupt-parent: Parent interrupt device, must be handle of palmas node. 7- interrupts: Interrupt number of RTC submodule on device. 8 9Optional properties: 10 11- ti,backup-battery-chargeable: The Palmas series device like TPS65913 or 12 TPS80036 supports the backup battery for powering the RTC when main 13 battery is removed or in very low power state. The backup battery 14 can be chargeable or non-chargeable. This flag will tells whether 15 battery is chargeable or not. If charging battery then driver can 16 enable the charging. 17- ti,backup-battery-charge-high-current: Enable high current charging in 18 backup battery. Device supports the < 100mA and > 100mA charging. 19 The high current will be > 100mA. Absence of this property will 20 charge battery to lower current i.e. < 100mA. 21 22Example: 23 palmas: tps65913@58 { 24 ... 25 palmas_rtc: rtc { 26 compatible = "ti,palmas-rtc"; 27 interrupt-parent = <&palmas>; 28 interrupts = <8 0>; 29 ti,backup-battery-chargeable; 30 ti,backup-battery-charge-high-current; 31 }; 32 ... 33 }; 34
