Subject: [PATCH v2 04/11] drm/rockchip: lvds: Harmonize function names
Date: Tue, 24 Dec 2019 15:38:53 +0100	[thread overview]
Message-ID: <20191224143900.23567-5-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20191224143900.23567-1-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_'.
