|  | 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>; | 
|  | }; |
