commit d644853ff8fcbb7a4e3757f9d8ccc39d930b7e3c upstream.
On Exynos5422/5800 the regulator supply for the A15 cores ("vdd_arm") is coupled with the regulator supply for the SoC internal circuits ("vdd_int"), thus all operating points that modify one of those supplies have to specify a triplet of the min/target/max values to properly work with regulator coupling.
