Subject: [RESEND PATCH v5 3/4] ARM: dts: exynos: add initial data for coupled regulators for Exynos5422/5800
Date: Thu, 8 Aug 2019 11:02:33 +0200 [thread overview]
Message-ID: <20190808090234.12577-4-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.
