Subject: [PATCH 1/3] ARM: dts: exynos: Adjust ldo23 and ldo27 to lower levels on Arndale Octa
Date: Sat,  9 Mar 2019 16:00:37 +0100	[thread overview]
Message-ID: <20190309150039.8705-1-krzk@kernel.org> (raw)

Although on the schematics of Insignal Arndale Octa board the
PVDD_MIFS_1V1 (ldo23) and PVDD_G3DS_1V0 (ldo27) are marked as 1.2 V, the
vendor v3.4 Android kernel sets them lower.  Also name suggests that
they should work on 1.1 V and 1.0 V respectively, not 1.2 V.
