Hi Lin,

can you confirm that the hardware isn't capable of raising interrupts
when programmable load thresholds are trespassed? From reading the
TRM, looks like it should be possible.

Or is there any reason to merge now a driver that polls for load stats?

Thanks,

The cover-letter includes the duplicate list of patches.

Also, I want to test the build test. but, When I apply these patches,
merge conflict happen. Could you give the information about base git repository?

[PATCH v4 0/7] rk3399 support ddr frequency scaling

2016-07-29 Thread Lin Huang 
rk3399 platform have dfi controller can monitor ddr load,
and dcf controller to handle ddr register so we can get the
right ddr frequency and make ddr controller happy work(which
will implement in bl31). So we do ddr frequency scaling with
following flow:

 kernelbl31

monitor ddr load
|
|
get_target_rate
|
|   pass rate to bl31
clk_set_rate(ddr) ->run dcf flow
|   |
|   |
wait dcf interrupt<---trigger dcf interrupt  
|
|
  return
