Subject: [PATCHv2 1/5] OMAP2xxx: HWMOD: fix DSS opt clocks
Date: Mon,  8 Aug 2011 12:15:10 +0300	[thread overview]
Message-ID: <1312794914-22894-2-git-send-email-tomi.valkeinen@ti.com> (raw)
In-Reply-To: <1312794914-22894-1-git-send-email-tomi.valkeinen@ti.com>

Set HWMOD_CONTROL_OPT_CLKS_IN_RESET for dss_core to allow DSS reset
properly.

Add missing ick opt-clock for rfbi. Rfbi uses the ick to calculate
timings.

Fix the venc iclk and fclk.
