From a422b171ac17edde296b48e2b3e9c9845d773609 Mon Sep 17 00:00:00 2001 From: Piotr Dymacz Date: Fri, 31 Jan 2020 15:22:54 +0100 Subject: base-files: diag: restore default trigger for 'boot' LED For devices without a dedicated 'diag' LED, we use sometimes one of other LEDs for indicating at least 'boot', 'failsafe' and 'upgrade' stages. In some cases, at the same time these LEDs have defined default triggers in DTS using 'linux,default-trigger' property. Current 'diag' setup removes the trigger and turns off 'boot' LED after bootup. One of the examples of such device is TP-Link TL-WR841N v14 (ramips) which uses 'wlan' LED with defined 'linux,default-trigger' for 'diag': aliases { led-boot = &led_wlan; led-failsafe = &led_wlan; led-upgrade = &led_wlan; }; [...] led_wlan: wlan { label = "tl-wr841n-v14:green:wlan"; gpios = <&gpio1 9 GPIO_ACTIVE_LOW>; linux,default-trigger = "phy0tpt"; }; This patch extends 'diag.sh' and 'leds.sh' scripts to make sure default trigger defined in DTS is restored for 'diag' LED which isn't used for indicating 'running' stage.
