help
Enable the common LED module supporting automatic control of the
battery and power LEDs.

bool "PWM (Pulse Width Modulation) LEDs"
depends on PLATFORM_EC_PWM
help
Enable PWM (Pulse Width Modulation) controlled LEDs that conform to
the Chromium OS LED behavior specification.
Your board files must implement the led_get_brightness_range() and
led_set_brightness() which are used by the LED PWM module to set the
board LEDs in response to power and charging events.
if PLATFORM_EC_LED_PWM
config PLATFORM_EC_LED_PWM_COUNT
int "Number of PWM LEDs"
default 1
help
This sets the number of PWM LEDs that are controlled by the common
PWM LED policy. The maximum number of PWM LEDs is currently 2.
TODO(b/177452529): Set this parameter from the device tree.
config PLATFORM_EC_CMD_LEDTEST
bool "Console command: ledtest"
default y
help
Enable the "ledtest" command. This command lets you override the
automatic control of the platform LEDs. For example:
ledtest 0 enable red
disables automatic control of the first PWM LED and forces the LED
color to red. Set the 2nd parameter to "disable" to return back
to automatic control:
ledtest 0 disable
