infineon,hibernate-wakeup

Description

Infineon hibernate / hibernate-RAM wakeup source configuration.

Infineon SoCs provide a set of dedicated hardware sources that can wake the
device from the hibernate (and, where supported, hibernate-RAM) power modes.
This binding describes the hibernate wakeup sources:

  PIN0, PIN1, LPCOMP0, LPCOMP1, WDT, RTC alarm

The pin-to-pad mapping is fixed in silicon and differs per device; consult
the SoC datasheet or the SoC devicetree for the mapping.  A device enables
only the sources it uses - set only the applicable properties below.

Each pin and LPCOMP source can be independently enabled and configured to wake
on a high or low logic level.

Example (wake on the first dedicated pin, active low):

  hibernate_wakeup: hibernate-wakeup {
      compatible = "infineon,hibernate-wakeup";
      wakeup-pin0-trigger = "low";
  };

Node specific properties

Properties not inherited from the base binding file.

Name	Type	Details
`wakeup-pin0-trigger`	`string`	Enable dedicated wake PIN0 as a hibernate wakeup source. The physical pad is device-specific (see the SoC devicetree/datasheet). Set to "low" to wake on a low logic level, "high" for a high level. Omit to disable PIN0. Legal values: `low`, `high`
`wakeup-pin1-trigger`	`string`	Enable dedicated wake PIN1 as a hibernate wakeup source. The physical pad is device-specific (see the SoC devicetree/datasheet). Set to "low" to wake on a low logic level, "high" for a high level. Omit to disable PIN1. Legal values: `low`, `high`
`wakeup-lpcomp0-trigger`	`string`	Enable low-power comparator 0 (LPCOMP0) as a hibernate wakeup source. Set to "low" to wake on a low output level, "high" for a high level. Omit to disable LPCOMP0. Legal values: `low`, `high`
`wakeup-lpcomp1-trigger`	`string`	Enable low-power comparator 1 (LPCOMP1) as a hibernate wakeup source. Set to "low" to wake on a low output level, "high" for a high level. Omit to disable LPCOMP1. Legal values: `low`, `high`
`wakeup-wdt`	`boolean`	Enable the watchdog timer as a hibernate wakeup source.
`wakeup-rtc-alarm`	`boolean`	Enable RTC alarm as a hibernate wakeup source.
