Subject: [PATCH RESEND 13/15] ARM: clps711x: edb7211: Control LCD backlight via PWM
Date: Wed,  5 Jun 2013 09:59:21 +0400	[thread overview]
Message-ID: <1370411967-29451-14-git-send-email-shc_work@mail.ru> (raw)
In-Reply-To: <1370411967-29451-1-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.
