Subject: [U-Boot] [PATCH v2 4/6] video: fsl_dcu_fb: Update DCU layers for Vybrid
Date: Thu, 30 Mar 2017 12:44:04 +0530 [thread overview]
Message-ID: <7686f5784f9dc014ea7ed36f25e7209b39d19016.1490856350.git.maitysanchayan@gmail.com> (raw)
In-Reply-To: <cover.1490856350.git.maitysanchayan@gmail.com>
From: Stefan Agner <stefan.agner@toradex.com>
Users control the graphical content of the panel by manipulating
configuration of elements in DCU4 called layers. The number of
layers is different for Vybrid and LS102XA SoC's. Update this
to reflect for LS102XA accordingly and for use with Vybrid.
