Subject: [PATCH v2 17/18] ARM: dts: imx6q-apalis: backlight pwm: Adapt brightness steps
Date: Wed, 15 Jun 2022 13:50:05 +0200 [thread overview]
Message-ID: <20220615115006.45672-18-max.oss.09@gmail.com> (raw)
In-Reply-To: <20220615115006.45672-1-max.oss.09@gmail.com>
From: Max Krummenacher <max.krummenacher@toradex.com>
Adapt the brightness steps as the backlight doesn't light up
for very low duty cycles.
