linux-toradex.git, branch T20_LinuxImageV2.0Beta1_20121218 Linux kernel for Apalis and Colibri modules tegra: colibri_t20: add more video modes 2012-12-17T14:52:00+00:00 Marcel Ziswiler marcel.ziswiler@toradex.com 2012-12-17T14:52:00+00:00 8ff26794f73da3caf815f348a03509f533b32ec2 Add the following tested (e.g. framebuffer console and X) video modes: - 1280x1024@60 - 1600x1200@60 - 1680x1050@60 - 1920x1080p - 1920x1200 And the following portrait modes: - 480x640 - 540x960 - 720x1280 The define TEGRA_FB_VGA in board-colibri_t20.h can be used to switch between VGA and 800x480. While at it fix rename of CAMERA_INTERFACE to COLIBRI_T20_VI as well. 
Add the following tested (e.g. framebuffer console and X) video modes:
- 1280x1024@60
- 1600x1200@60
- 1680x1050@60
- 1920x1080p
- 1920x1200

And the following portrait modes:
- 480x640
- 540x960
- 720x1280

The define TEGRA_FB_VGA in board-colibri_t20.h can be used to switch
between VGA and 800x480.

While at it fix rename of CAMERA_INTERFACE to COLIBRI_T20_VI as well.
