description: LED colors parent node
compatible: "cros-ec,led-colors"
child-binding:
description: LED Color nodes to describe the policy combination a node
depends on, and the color to set to for that combination.
e.g. If Blue color needs to be set for charge state discharge
in S0, a node looks like
power-state-discharge-s0 {
charge-state = "PWR_STATE_DISCHARGE";
chipset-state = "POWER_S0";
color-0 {
led-color = "LED_BLUE";
};
};
properties:
charge-state:
description: If the LED color depends on charge state, this
property is used to describe it.
type: string
required: false
enum:
- PWR_STATE_CHARGE
- PWR_STATE_DISCHARGE
- PWR_STATE_ERROR
- PWR_STATE_IDLE
- PWR_STATE_CHARGE_NEAR_FULL
charge-port:
description: If the LED color depends on the charging port (left or right)
type: int
required: false
chipset-state:
description: If the LED color depends on chipset state, this
property is used to describe it.
type: string

enum:
- POWER_S0

extra-flag:
description: If the LED color depends on additional factors
type: string
required: false
enum:
- NONE
- LED_CHFLAG_FORCE_IDLE
- LED_CHFLAG_DEFAULT

led-id:
description: Used to link the color nodes with the pin nodes in
case of multiple LEDs.

period-ms:
description: In case of blinking LEDs, amount of time in msecs
the LED color is active. This value must be a
multiple of HOOK_TICK_INTERVAL_MS
e.g.
power-state-error {
charge-state = "PWR_STATE_ERROR";
/* One sec Amber, one sec Off */
color-0 {
