Hi zhang,
File "arch/arm/mach-mx6/cpu_op-mx6.c":
/* working point(wp): 0 - 1.2GHz; 1 - 792MHz, 2 - 498MHz 3 - 396MHz */ static struct cpu_op mx6q_cpu_op_1_2G[] = { { .pll_rate = 1200000000, .cpu_rate = 1200000000, .cpu_podf = 0, .pu_voltage = 1275000, .soc_voltage = 1275000, .cpu_voltage = 1275000,}, { ...... Here are defined the working point used by DVFS logic to set frequency and core voltage of i.MX6. With a careful hack of that value we can modify max working speed of our board. To mantain cpu core stability while increasing frequency rate, a correspondent core voltage enhancement can be required.

uboot和kernel源码中并没有这个文件。。。。我用的官方的imx6qp sabresd sdb板子,跑Android 6.0,请问该怎么修改CPU频率呢,另外ldo的bootimage该怎么编译呢?
