Subject: [PATCH 1/2] ARM: dts: modify rk3288 jaq backlight-level
Date: Mon, 7 Dec 2015 21:11:08 +0800 [thread overview]
Message-ID: <1449493869-32151-1-git-send-email-wxt@rock-chips.com> (raw)
the panel which jaq use require 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%.
