Subject: [PATCH] arm64: dts: mt8183: Add missing power-domain for pwm0 node
Date: Wed, 13 Jan 2021 22:57:23 +0100 [thread overview]
Message-ID: <20210113215723.71966-1-enric.balletbo@collabora.com> (raw)
The MT8183 display PWM device will not work until the associated
power-domain is enabled. Add the power-domain reference to the node
allows the display PWM driver to operate and the backlight turn on.
Fixes: f15722c0fef0 ("arm64: dts: mt8183: Add pwm and backlight node")
