Subject: [PATCH 7/7] omap4: dpll: Enable auto gate control for all MX postdividers
Date: Tue, 8 Feb 2011 15:40:38 +0530 [thread overview]
Message-ID: <1297159838-30282-8-git-send-email-rnayak@ti.com> (raw)
In-Reply-To: <1297159838-30282-7-git-send-email-rnayak@ti.com>
Enable hardware gate control for all dpll MX postdividers.
This requires the allow_idle/deny_idle functions to be
populated for all clock nodes (mx post dividers) in
clkops.
