Posted by Mark Tseng 3 weeks, 5 days ago

For multi cluster SoC, the cpufreq->target_index() is re-enter function
for each policy to change CPU frequency. In the cirtical session must
use glocal mutex lock to avoid get wrong OPP.

	  - remove CCI transition_delay patch

Mark Tseng (3):
  cpufreq: mediatek: using global lock avoid race condition
  cpufreq: mediatek: Add CPUFREQ_ASYNC_NOTIFICATION flag
  cpufreq: mediatek: data safety protect
