description: GPIO LED pins parent node
compatible: "cros-ec,gpio-led-pins"
child-binding:
description: |
Each child node describes all the GPIO pins that need to be altered to set
a specific color.
e.g. For a board supporting Blue and Amber LEDs - to set LED_AMBER color,
amber LED will need to be set to 1 and blue LED to 0. 1 always turns on
the LED and 0 always turns off the LED. So a node looks like
color-amber {
led-color = "LED_AMBER";
led-pins = <&gpio_ec_chg_led_y_c1 1>,
<&gpio_ec_chg_led_b_c1 0>;
};
properties:
led-color:
type: string
required: true
description: |
This property is used to identify pin nodes based on color enum.
It is required by the EC_CMD_LED_CONTROL host command.
enum:
- LED_OFF
- LED_RED
- LED_GREEN
- LED_BLUE
- LED_YELLOW
- LED_WHITE
- LED_AMBER
led-id:
type: string
required: true
description: |
This property is required by the EC_CMD_LED_CONTROL host command.
It must match the enum names defined in ec_commands.h.
enum:
- EC_LED_ID_BATTERY_LED
- EC_LED_ID_POWER_LED
- EC_LED_ID_ADAPTER_LED
- EC_LED_ID_LEFT_LED
- EC_LED_ID_RIGHT_LED
- EC_LED_ID_RECOVERY_HW_REINIT_LED
- EC_LED_ID_SYSRQ_DEBUG_LED
br-color:
type: string
required: false
description: |
This is used in the ectool brightness range APIs. It must match
the enum names defined in ec_commands.h.
enum:
- EC_LED_COLOR_RED
- EC_LED_COLOR_GREEN
- EC_LED_COLOR_BLUE
- EC_LED_COLOR_YELLOW
- EC_LED_COLOR_WHITE
- EC_LED_COLOR_AMBER
led-pins:
type: phandle-array
required: true
description: |
This property is used to specify an array of gpio pins and
corresponding values to enable a particular color.
e.g. Amber color - led-pins = <&gpio_ec_chg_led_y_c1 1>,
<&gpio_ec_chg_led_b_c1 0>;
