[PATCH v2 8/8] drm/kmb: Enable support for fbcon (framebuffer console)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Edmund Dea <edmund.j.dea@xxxxxxxxx>

Enable support for fbcon (framebuffer console).
The user can initialize fbcon by loading kmb-drm with the parameter
console=1.

v2: added missing static clk_enable
