Subject: [PATCH v2 3/3] ARM: dts: exynos: Lower SD card interface voltage to 2.8v on Odroid X/X2/U3
Date: Wed, 27 Apr 2016 16:00:20 +0200 [thread overview]
Message-ID: <1461765620-6833-3-git-send-email-k.kozlowski@samsung.com> (raw)
In-Reply-To: <1461765620-6833-1-git-send-email-k.kozlowski@samsung.com>
Odroid X/X2/U3 schematics say that SD card vmmc regulator
(LDO21/TFLASH) operates on 2.8 V. Mainline U-Boot uses that value as
well. 2.8 V is common on Exynos-based boards. Additionally use some
descriptive name for this regulator.
