Subject: [PATCH v2 2/5] arm64: dts: mediatek: asurada: Add display backlight
Date: Thu, 6 Oct 2022 17:25:25 -0400 [thread overview]
Message-ID: <20221006212528.103790-3-nfraprado@collabora.com> (raw)
In-Reply-To: <20221006212528.103790-1-nfraprado@collabora.com>
Add the display backlight for the Asurada platform. It relies on the
display PWM controller, so also enable and configure this component.
