[PATCH 04/21] ARM: OMAP: dss-common: use new display drivers

Tomi Valkeinen tomi.valkeinen at ti.com
Fri Jul 26 03:08:07 EDT 2013


Use the new display drivers for OMAP4 Panda and OMAP4 SDP boards.

The new OMAP display drivers were merged for 3.11, and we can now change
the board files to use the new ones and phase out the old ones.
