Subject: [PATCH 3/3] ARM: dts: imx6sll-evk: enable SEIKO 43WVF1G lcdif panel
Date: Fri, 13 Jul 2018 15:58:27 +0800 [thread overview]
Message-ID: <1531468707-25737-3-git-send-email-Anson.Huang@nxp.com> (raw)
In-Reply-To: <1531468707-25737-1-git-send-email-Anson.Huang@nxp.com>
Enable SEIKO 43WVF1G lcdif panel for DRM driver,
add necessary properties according to SEIKO 43WVF1G
driver's requirement, such as "dvdd-supply", "avdd-supply"
and "backlight" etc..
