2011-02-25omap4: dpll: Enable auto gate control for all MX postdividersRajendra Nayak
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. Signed-off-by: Rajendra Nayak <rnayak@ti.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>
2011-02-25OMAP4: DPLL: Add dpll api to control GATE_CTRLRajendra Nayak
On OMAP4, the dpll post divider outputs (MX outputs) along with clockout_x2 output provide a way to allow/deny hardware level autogating. Allowing autoidle would mean that the hw would autogate this clock when there is no dependency for it. Denying idle would mean that this clock output will be forced to stay enabled. Add dpll api's to read/allow/deny idle control for these dpll mx postdividers. NOTE: The gatectrl bit set to 0 allows gatectrl, and the bit set to 1 denies gatectrl.
