Subject: [PATCH 5.7 376/393] ARM: dts: exynos: Extend all Exynos5800 A15s OPPs with max voltage data
From: Marek Szyprowski <m.szyprowski@...sung.com>
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.
Fixes: eaffc4de16c6 ("ARM: dts: exynos: Add missing CPU frequencies for Exynos5422/5800")
