Subject: [PATCH 3/3] ARM: dts: exynos: Lower SD card interface voltage to 2.8v on Odroid X/X2/U3
Date: Wed, 27 Apr 2016 14:19:13 +0200	[thread overview]
Message-ID: <1461759553-10119-3-git-send-email-k.kozlowski@samsung.com> (raw)
In-Reply-To: <1461759553-10119-1-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.
