[U-Boot] [PATCH v1 6/6] board: toradex: colibri_vf: Add DCU support for Colibri Vybrid
Sanchayan Maity
maitysanchayan at gmail.com
Mon Feb 6 07:30:34 UTC 2017
From: Stefan Agner <stefan.agner at toradex.com>
The Vybrid SoC family has the same display controller unit (DCU)
like the LS1021A SoC. This patch adds platform data, pinmux defines
and clock control to enable the driver for Toradex Colibri Vybrid
module.
