Subject: [PATCH 13/15] ARM: clps711x: edb7211: Control LCD backlight via PWM
Date: Mon, 13 May 2013 21:07:35 +0400 [thread overview]
Message-ID: <1368464857-5038-16-git-send-email-shc_work@mail.ru> (raw)
In-Reply-To: <1368464857-5038-1-git-send-email-shc_work@mail.ru>
This patch provide control LCD backlight via PWM. GPIO is used
only for switch backlight ON and OFF.
