Subject: [PATCH v3 4/5] ARM: dts: exynos: add initial data for coupled regulators for Exynos5422/5800
Date: Fri, 19 Jul 2019 17:05:34 +0200 [thread overview]
Message-ID: <20190719150535.15501-5-k.konieczny@partner.samsung.com> (raw)

From: Marek Szyprowski <m.szyprowski@samsung.com>
Declare Exynos5422/5800 voltage ranges for opp points for big cpu core and
bus wcore and couple their voltage supllies as vdd_arm and vdd_int should
be in 300mV range.
