From ddcb39d4c8efa4bedf645c0ba5aba74a0cd2dcf0 Mon Sep 17 00:00:00 2001 From: Willy Tarreau Date: Fri, 30 Dec 2016 19:06:59 +0100 Subject: ARM: dts: rockchip: fix the MiQi board's LED definition The MiQi board's green LED doesn't work at all with the mainline kernel. There are multiple reasons to this. First, the gpio number is wrong, it is declared on gpio220 (chip 7 pin 4) instead of gpio218 (chip 7 pin 2). Second, a pinctrl is referenced, also declared with the same wrong value while it is not unused. Third, the GPIO polarity was wrong (active low instead of active high) with the default value set to "default-on", resulting in the LED being turned off even when the GPIO is correct. This patch fixes all these inconsistencies at once since these they are related to each other, and also restores the "timer" trigger which is the same as the one used by the kernels shipped with the board. It's important to note that during the port to mainline, the led's label was changed from "System" to "miqi:green:user", so scripts making use of the name will still not work until they're fixed.
