From afe2cf08401638fbf1bfaf7234be7eb3a5778b04 Mon Sep 17 00:00:00 2001 From: Tero Kristo Date: Mon, 2 Mar 2015 16:24:26 +0200 Subject: [PATCH] ARM: OMAP3: dpll3-m2: get rid of obsolete clksel access Core DVFS support code is currently referencing clksel functionality, which is wrong. The m2 divisor has been implemented as a divider clock for a long time already, so replace the validrate check call with proper functionality. Core DVFS is currently not supported in the kernel so verifying this patch can be rather tricky, this should probably be fixed at some point.
