| Subject: ARM: dts: exynos: Extend all Exynos5800 A15's OPPs with max voltage data |
| |
| From: Marek Szyprowski <m.szyprowski@samsung.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") |
