Subject: [PATCHv2 11/28] OMAP: DSS2: Add FEAT_VENC_REQUIRES_TV_DAC_CLK
Date: Thu, 09 Jun 2011 13:56:33 +0000	[thread overview]
Message-ID: <1307627810-3768-12-git-send-email-tomi.valkeinen@ti.com> (raw)
In-Reply-To: <1307627810-3768-1-git-send-email-tomi.valkeinen@ti.com>

OMAP3430 requires an 96MHz clock to VENC's DAC, but no other OMAP needs
it.

Add a new feature, FEAT_VENC_REQUIRES_TV_DAC_CLK, which tells if the
clock is needed on this platform, and use that feature in venc.c to
decide if the clock needs enabling.
