Subject: [PATCH 7/9] video: stm: honor display_flags
Date: Mon,  6 Jul 2015 12:36:12 +0200	[thread overview]
Message-ID: <1436178974-20064-7-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1436178974-20064-1-git-send-email-s.hauer@pengutronix.de>

stmfb uses custom flags FB_SYNC_DE_HIGH_ACT and FB_SYNC_CLK_INVERT.
These have generic counterparts in display_flags. Honor them aswell.
