Subject: [PATCH 04/12] drm/rockchip: lvds: Harmonize function names
Date: Fri, 13 Dec 2019 19:10:43 +0100 [thread overview]
Message-ID: <20191213181051.25983-5-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20191213181051.25983-1-miquel.raynal@bootlin.com>
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_'.
