ARM: shmobile: r8a7790/lager dts: Add DVFS parameters into cpu0 node for r8a7790
Add needed information inside CPU0 for the generic cpufreq-cpu0 driver.
- voltage-tolerance = 1%
It reflects the tolerance for the CPU voltage defined inside the OPP
table. Due to the lack of proper OPP definition, use an arbitrary safe
value.
- clock-latency = 300 us
Approximate worst-case latency to do a full DVFS transition for every
OPPs. Due to the lack of HW information, use an arbitrary safe value.
Note: The term transition-latency will be more accurate to define this
value since the clock transition latency is not the only parameter that
will define the overall DVFS transition.
- operating-points = < kHz - uV >
List of 6 operating points. All of them are using the same voltage
since the valid Vmin voltage is not documented in the HW spec.
- clocks
phandle to the CPU clock source. This clock source is used for all the
4 CortexA15 located inside the same cluster.
