[U-Boot] [PATCH v3 6/6] board: toradex: colibri_vf: Add DCU support for Colibri Vybrid
Sanchayan Maity

Tue Apr 11 05:42:14 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.
