Subject: [PATCH 2/2] arm64: dts: meson: libretech-cc: switch eMMC to 1.8v
Date: Thu, 20 Dec 2018 17:10:37 +0100 [thread overview]
Message-ID: <20181220161037.23756-3-jbrunet@baylibre.com> (raw)
In-Reply-To: <20181220161037.23756-1-jbrunet@baylibre.com>
While some 3.3v eMMC 4.0 are available from libretech, the default
option for the aml-s905x-cc seems to 1.8v 5.0 modules.
