   4 Subject: ARM: OMAP2+: add missing lateinit hook for calling pm late init
   5
   6 AM335x, AM43xx, OMAP5 and DRA7 have missing late init hook. Introduce
   7 SoC specific hook with a call to OMAP2+ generic lateinit hook. This
   8 allows the generic late initializations such as cpufreq hooks to be
   9 active.
  10
  11 Based on out-of-tree patches that need to be introduced in
  12 mainline, this introduction allows us to provide the foundation for
  13 further SoC specific features as they are developed.
