From f0d2f68a6387867c4748bc94c9b0165a49701204 Mon Sep 17 00:00:00 2001 From: Tero Kristo Date: Fri, 3 Oct 2014 16:57:10 +0300 Subject: ARM: OMAP3: clock: use clk_features flags for omap3 DPLL4 checks DPLL4 can't be reprogrammed on OMAP3430 ES1.0 due to hardware limitation. Currently, the code does runtime omap_rev() check to see the chip it is being executed on, instead, change this to use clk_features flags. This avoids need for runtime omap_rev() checks.
