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.
Fixes: eaffc4de16c6 ("ARM: dts: exynos: Add missing CPU frequencies for Exynos5422/5800")

Thanks, applied with Cc-stable to next/dt-late. It might miss this merge
window and in such case I will keep it for v5.9 cycle.
Best regards,
Krzysztof
