   1 ipq806x: support independent core clocks with kernel 4.9+
   2
   3 Add back support for the independent_clocks definition that has been
   4 removed between kernel 4.4 and 4.9 by upstream commits
   5 eb96924acddc709db58221c210ca05cd9effb1df and
   6 e86eee6bc2aaa6b3637f6497b26beee09a91bde9
   7
   8 * extend the new cpufreq_dt_platform_data definition in cpufreq-dt.h
   9 * use new cpufreq-dt.h in qcom-cpufreq.c
