Subject: [PATCH v2 7/7] omap4: dpll: Enable auto gate control for all MX postdividers
Date: Thu, 10 Feb 2011 14:46:40 +0530 [thread overview]
Message-ID: <1297329400-5936-8-git-send-email-rnayak@ti.com> (raw)
In-Reply-To: <1297329400-5936-7-git-send-email-rnayak@ti.com>
Enable hardware gate control for all dpll MX and X2 postdividers.
This requires the allow_idle/deny_idle functions to be
populated for all clock nodes (mx/x2 post dividers) in
clkops.
