Change CPU frequency of OMAPL138

Dear all,

          I want to check if we want to update the CPU frequency of the OMAPL 138, besides the following two steps:     

          1. Change  Core_300MHz_mDDR_150MHz() to Core_456MHz_mDDR_150MHz() in OMAPL138_LCDK.gel,   

          2. Update  #define SOC_SYSCLK_1_FREQ         (300000000) to (456000000) in soc_OMAPL138.h，

          Do we need to change any other components?

          Thanks a lot!
