Subject[PATCH v2 04/11] drm/rockchip: lvds: Harmonize function names
Date
Prepare the introduction of PX30 support by clarifying the function
prefixes.

We continue to prefix with 'rockchip_lvds_' generic functions that are
not specific to a single hardware. Functions implying hardware
modifications are now prefixed with 'rk3288_lvds_'.
