From 83ccc4670477e7722d4654ca44b4b7004fcaada9 Mon Sep 17 00:00:00 2001 From: Tero Kristo Date: Fri, 12 Dec 2014 15:22:01 +0200 Subject: ARM: OMAP3: clock: fix boot breakage in legacy mode The new usage of determine_rate and set_rate_and_parent calls for OMAP DPLLs assumes the DPLLs must have two parents defined, even if it is the same clock. Legacy clock data did not fullfill this requirement and caused a boot crash. Fixed by adding the missing parent information to the DPLL clocks.
