From 826f35f9b57c4581ff69d55c3bade9c3814e29bb Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 14 Jan 2016 18:10:48 -0700 Subject: video: Allow selection of the driver and font size Provide a way for the video console driver to be selected. This is controlled by the video driver's private data. This can be set up when the driver is probed so that it is ready for the video_post_probe() method. The font size is provided as well. The console driver may or may not support this depending on its capability.
