Subject: [PATCH 01/12] OMAP4: clock data: Add control for pad_clks_ck and slimbus_clk
Date: Mon, 13 Dec 2010 23:34:44 -0700	[thread overview]
Message-ID: <20101214063443.21555.55086.stgit@twilight.localdomain> (raw)
In-Reply-To: <20101214063308.21555.76050.stgit@twilight.localdomain>

From: Benoit Cousson <b-cousson@ti.com>

The gating of pad_clks and slimbus_ck is controlled by the PRCM, but
since the clock source is external, this is the SW responsability
to gate / un-gate it when the mcpdm or slimbus module need to be used.
There is no autogating possible with such external clock.

Add SW control to enable / disable this SW gating in the pad_clks_ck
and slimbus_clk clock node.
