You may want to introduce regulator coupling between CPU supplies and
their respective SRAM supplies, as they are driven by separate
physical regulators and will go out of sync when cpufreq tries to
adjust frequency and voltage of the CPU cluster under load. See [1].
So perhaps:
+ regulator-coupled-with = <&vdd_cpu_big1_mem_s0>;
+ regulator-coupled-max-spread = <10000>;
