Subject: [PATCH V3] ARM: dts: imx6q-logicpd: Fix broken PWM
Date: Wed, 19 Aug 2020 14:59:44 -0500 [thread overview]
Message-ID: <20200819195944.2866832-1-aford173@gmail.com> (raw)
The DTC doesn't like the default PWM settings, because it's expecting
three cells. This patch reduces adds the extra entry of 0 to the PWM
reference.
Fixes: fa28d8212ede ("ARM: dts: imx: default to #pwm-cells = <3> in the SoC dtsi files")
