This patch wires up the -brightness_get method for leds-gpio so that user-space can monitor -the LED value via /sys/class/gpio/led1/brightness. Using the input -trigger this returns an indication of the system power health, -otherwise it is just whatever value the trigger has written most -recently. - -See: https://github.com/raspberrypi/linux/issues/1064 ---- - drivers/leds/leds-gpio.c | 8 ++++++++ - 1 file changed, 8 insertions(+) - ---- a/drivers/leds/leds-gpio.c -+++ b/drivers/leds/leds-gpio.c -@@ -82,6 +82,13 @@ static void gpio_led_set(struct led_clas - } - } - -+static enum led_brightness gpio_led_get(struct led_classdev *led_cdev) -+{ -+ struct gpio_led_data *led_dat = -+ container_of(led_cdev, struct gpio_led_data, cdev); -+ return gpiod_get_value_cansleep(led_dat->gpiod) ?
