From a38884f681a4d044befd30d9f3d19a0821bae63a Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Tue, 12 Mar 2013 10:15:43 +0200 Subject: [PATCH] videomode: simplify videomode Kconfig and Makefile This patch simplifies videomode related Kconfig and Makefile. After this patch, there's only one non-user selectable Kconfig option left, VIDEOMODE_HELPERS. The reasons for the change: * Videomode helper functions are not something that should be shown in the kernel configuration options. The related code should just be included if it's needed, i.e. selected by drivers using videomode. * There's no need to have separate Kconfig options for videomode and display_timing. First of all, the amount of code for both is quite small. Second, videomode depends on display_timing, and display_timing in itself is not really useful, so both would be included in any case. * CONFIG_VIDEOMODE is a bit vague name, and CONFIG_VIDEOMODE_HELPERS describes better what's included.
