2018-11-28soc: amlogic: Add Meson Clock Measure driverNeil Armstrong
The Amlogic Meson SoCs embeds a clock measurer IP to measure the internal clock paths frequencies. The precision is determined by stepping into the duration until the counter overflows. The debugfs slows a pretty summary and each clock can be measured individually aswell.
