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

[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:

	     kernel                                bl31

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