From 11c32d7b6274cb0f554943d65bd4a126c4a86dcd Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Thu, 22 May 2014 23:25:14 +0200 Subject: video: move Versatile CLCD helpers This moves the Versatile-specific helper code and panel database down into the drivers/video folder next to the CLCD driver itself, preserving the config symbol but also moving the header to platform data. This is necessary to rid the Integrator of this final inclusion dependency and get us one less user of the plat-versatile folder.
