From 21e4c9306bd20ab4e02f90cd452d90bc4e4a0a98 Mon Sep 17 00:00:00 2001 From: Phil Elwell Date: Wed, 3 Jul 2019 20:37:14 +0100 Subject: [PATCH] overlays: Correct gpio-fan gpio flags for 4.19 The gpio-fan overlay was submitted for the 4.14 kernel where the second value in the Device Tree gpios declaration was ignored (thanks to an old-style driver), allowing the fan-control output to be active-high even though the declaration appears to request it be active-low. The gpio-fan driver in 4.19 uses GPIO descriptors and honours the active-low flag that the overlay (accidentally?) supplies. Change/correct the flags field to mark the GPIO as active-high.
