Subject: [PATCH 06/10] ARM: dts: rockchip: add rk3288-veyron-jaq backlight and panel overrides
Date: Fri, 18 Mar 2016 02:40:02 +0100 [thread overview]
Message-ID: <1458265206-15733-7-git-send-email-heiko@sntech.de> (raw)
In-Reply-To: <1458265206-15733-1-git-send-email-heiko@sntech.de>
From: Caesar Wang <wxt@rock-chips.com>
The panel which jaq uses requires the pwm duty cycle larger than 3%,
when the backlight status from power off to power on, otherwise the
backlight will flush, so we modify the second brightness-level to 8,
and when the backlight from power off to power on the pwm duty cycle
will larger than 3%.
