| 2 | |
| 3 | Required properties: |
| 4 | - compatible: |
| 5 | - "ti,palmas-rtc" for palma series of the RTC controller |
| 6 | - interrupts: Interrupt number of RTC submodule on device. |
| 7 | |
| 8 | Optional properties: |
| 9 | |
| 10 | - ti,backup-battery-chargeable: The Palmas series device like TPS65913 or |
| 11 | TPS80036 supports the backup battery for powering the RTC when main |
| 12 | battery is removed or in very low power state. The backup battery |
| 13 | can be chargeable or non-chargeable. This flag will tells whether |
| 14 | battery is chargeable or not. If charging battery then driver can |
| 15 | enable the charging. |
| 16 | - ti,backup-battery-charge-high-current: Enable high current charging in |
| 17 | backup battery. Device supports the < 100uA and > 100uA charging. |
| 18 | The high current will be > 100uA. Absence of this property will |
| 19 | charge battery to lower current i.e. < 100uA. |

| 21 | Example: |
| 22 | palmas: tps65913@58 { |
| 23 | ... |
| 24 | palmas_rtc: rtc { |
| 25 | compatible = "ti,palmas-rtc"; |
| 26 | interrupt-parent = <&palmas>; |
| 27 | interrupts = <8 0>; |
| 28 | ti,backup-battery-chargeable; |
