Subject: [PATCH v3 4/4] OMAP4: DSS2: clocks: Add ick as dummy clock
Date: Mon, 31 Jan 2011 21:57:46 +0530	[thread overview]
Message-ID: <1296491266-6949-5-git-send-email-sumit.semwal@ti.com> (raw)
In-Reply-To: <1296491266-6949-1-git-send-email-sumit.semwal@ti.com>

DSS code uses ick as one of the clocks in clk_get/clk_put. OMAP4 clock database
doesn't have ick for DSS, so adding ick as dummy clock.

This is needed for backward compatibility with OMAP2/3.

Once pm_runtime* APIs get introduced in DSS, this will be revisited.
