[PATCH 7/7] omap4: dpll: Enable auto gate control for all MX postdividers

Rajendra Nayak rnayak at ti.com
Tue Feb 8 05:10:38 EST 2011


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.
