The MAX42500 component structure of the nodes and properties of the serial interfaces and the I/O ports to access, control and configure the voltage monitors, and to program the power sequence timestamp recordings and the windowed watchdog timing. Signed-off-by: Kent Libetario <Kent.Libetario@analog.com>
The MAX42500 is a multiple function device for power system monitoring, power sequence timestamp recordings and windowed watchdog combined all- together in one SoC package. These features can be used independently or at the same time in a wide range of applications. Signed-off-by: Kent Libetario <Kent.Libetario@analog.com>
The MAX42500 supports standard power management, hwmon and watchdog ABI and sysfs attribute entries to expose the sensor data of the voltage monitors, power sequence timestamp recordings and windowed watchdog to the userspace. Signed-off-by: Kent Libetario <Kent.Libetario@analog.com>
The MAX42500 is a SoC power-system monitor with up to seven voltage monitor inputs that has programmable OV/UV thresholds and support DVS by I2C interface. Also, it has a programmable flexible power sequence recorder that stores the power-up and power-down timestamps separately. Signed-off-by: Kent Libetario <Kent.Libetario@analog.com>
The MAX42500 contains a programmable windowed watchdog and can be used either as simple mode windowed watchdog or challenge-and-response mode watchdog, which is accessible through the I2C interface, along with a configurable RESET output. Signed-off-by: Kent Libetario <Kent.Libetario@analog.com>
