[PATCH v2 8/9] omap4: dpll: Enable auto gate control for all MX postdividers

Fri Feb 4 04:59:03 EST 2011


From: Rajendra Nayak <rnayak at 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.

The autogen script is updated for the same.
