From c27e445527e949f3ef46d5326066196969c17d23 Mon Sep 17 00:00:00 2001 From: Myy Date: Sun, 12 Mar 2017 19:43:15 +0000 Subject: [PATCH 06/28] ARM: dts: rockchip: add the MiQi board's fan definition The MiQi board is sold with an enclosure in which a fan is connected to the second LED output, and configured by default in "heartbeat" mode so that it rotates slowly and increases when the CPU load increases, ensuring appropriate cooling by default. This LED output is called "Fan" in the original kernel and connected to GPIO18 (gpiochip 0, pin 18). Here we called it "miqi:green:fan" to stay consistent with the kernel's naming conventions. It's worth noting that without this patch the fan doesn't work at all, risking to make the board overheat.
