We take care of +all common DT properties (label, default trigger, state, etc.), however +some triggers may want to support more of them. + +It could be useful for timer trigger to support setting delay on/off +values with Device Tree property. Or for transient trigger to support +e.g. duration property. + +We obviously should handle such properties in triggers, not in generic +code. To let trigger drivers read properties from DT node we need to set +of_node to point the relevant node. This change allows using all kind of +of helpers in e.g. "activate" callbacks. + +Signed-off-by: Rafał Miłecki <zajec5@gmail.com> +Signed-off-by: Jacek Anaszewski <j.anaszewski@samsung.com> +--- + drivers/leds/leds-gpio.c | 5 +++-- + 1 file changed, 3 insertions(+), 2 deletions(-) + +--- a/drivers/leds/leds-gpio.c ++++ b/drivers/leds/leds-gpio.c +@@ -182,6 +182,7 @@ static struct gpio_leds_priv *gpio_leds_ + return ERR_PTR(-ENOMEM); + + device_for_each_child_node(dev, child) { ++ struct gpio_led_data *led_dat = &priv->leds[priv->num_leds]; + struct gpio_led led = {}; + const char *state = NULL; + +@@ -220,12 +221,12 @@ static struct gpio_leds_priv *gpio_leds_ + if (fwnode_property_present(child, "retain-state-suspended")) + led.retain_state_suspended = 1; + +- ret = create_gpio_led(&led, &priv->leds[priv->num_leds], +- dev, NULL); ++ ret = create_gpio_led(&led, led_dat, dev, NULL); + if (ret < 0) { + fwnode_handle_put(child); + goto err; + } ++ led_dat->cdev.dev->of_node = np; + priv->num_leds++; + } + |
