Subject: [PATCH v2 3/4] ARM: dts: exynos: add initial data for coupled regulators for Exynos5422/5800
Date: Mon, 15 Jul 2019 14:04:15 +0200
Message-ID: <20190715120416.3561-4-k.konieczny@partner.samsung.com> (raw)
In-Reply-To: <CGME20190715120432eucas1p1b32d72d239420b861bf8596d4e8a053d@eucas1p1.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.
