From 49642ac816a714f3037b7cd6401a46c8fe46e795 Mon Sep 17 00:00:00 2001 From: Jon Hunter Date: Fri, 7 Oct 2011 00:53:01 -0600 Subject: [PATCH] ARM: OMAP3+: dpll: use DPLLs recalc function instead of omap2_get_dpll_rate This is a continuation of Mike Turquette's patch "OMAP3+: use DPLL's round_rate when setting rate". omap3_noncore_dpll_set_rate() and omap3_noncore_dpll_enable() call omap2_get_dpll_rate() explicitly. It may be necessary for some DPLLs to use a different function and so use the DPLLs recalc() function pointer instead. An example is the DPLL_ABE on OMAP4 which can have a 4X multiplier in addition to the usual MN multipler and dividers and therefore uses a different round_rate and recalc function.
