[PATCH 5.4 307/408] arm64: dts: qcom: msm8916: Fix MDP/DSI interrupts

From: Greg Kroah-Hartman
Date: Tue Oct 27 2020 - 10:44:21 EST


From: Stephan Gerhold <stephan@xxxxxxxxxxx>

[ Upstream commit 027cca9eb5b450c3f6bb916ba999144c2ec23cb7 ]

The mdss node sets #interrupt-cells = <1>, so its interrupts
should be referenced using a single cell (in this case: only the
interrupt number).

However, right now the mdp/dsi node both have two interrupt cells
set, e.g. interrupts = <4 0>. The 0 is probably meant to say
IRQ_TYPE_NONE (= 0), but with #interrupt-cells = <1> this is
actually interpreted as a second interrupt line.

Remove the IRQ flags from both interrupts to fix this.
