1 | Palmas RTC controller bindings |
2 | ||
3 | Required 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 | ||
9 | Optional 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 | |
3b567271 DNS |
18 | backup battery. Device supports the < 100uA and > 100uA charging. |
19 | The high current will be > 100uA. Absence of this property will | |
20 | charge battery to lower current i.e. < 100uA. | |
