| Binding for the LTC2952 PowerPath controller |
| |
| This chip is used to externally trigger a system shut down. Once the trigger has |
| been sent, the chip's watchdog has to be reset to gracefully shut down. |
| A full powerdown can be triggered via the kill signal. |
| |
| Required properties: |
| |
| - compatible: Must contain: "lltc,ltc2952" |
| - watchdog-gpios: phandle + gpio-specifier for the GPIO connected to the |
| chip's watchdog line |
| - kill-gpios: phandle + gpio-specifier for the GPIO connected to the |
| chip's kill line |
| |
| Optional properties: |
| - trigger-gpios: phandle + gpio-specifier for the GPIO connected to the |
| chip's trigger line. If this property is not set, the |
| trigger function is ignored and the chip is kept alive |
| until an explicit kill signal is received |
| |
| Example: |
| |
| ltc2952 { |
| compatible = "lltc,ltc2952"; |
| |
| trigger-gpios = <&gpio0 1 GPIO_ACTIVE_LOW>; |
| watchdog-gpios = <&gpio1 2 GPIO_ACTIVE_HIGH>; |
| kill-gpios = <&gpio0 2 GPIO_ACTIVE_LOW>; |
| }; |
