| ST M41T80 family of RTC and compatible |
| |
| Required properties: |
| - compatible: should be one of: |
| "st,m41t62", |
| "st,m41t65", |
| "st,m41t80", |
| "st,m41t81", |
| "st,m41t81s", |
| "st,m41t82", |

| "st,m41t84", |
| "st,m41t85", |
| "st,m41t87", |
| "microcrystal,rv4162", |
| - reg: I2C bus address of the device |
| |
| Optional properties: |
| - interrupts: rtc alarm interrupt. |
| - clock-output-names: From common clock binding to override the default output |
| clock name |
| - wakeup-source: Enables wake up of host system on alarm |
| |
| Optional child node: |
| - clock: Provide this if the square wave pin is used as boot-enabled fixed clock. |
| |
| Example: |
| rtc@68 { |
| compatible = "st,m41t80"; |
| reg = <0x68>; |
| interrupt-parent = <&UIC0>; |
| interrupts = <0x9 0x8>; |
| |
| clock { |
| compatible = "fixed-clock"; |
| #clock-cells = <0>; |
| clock-frequency = <32768>; |
| }; |
| }; |
