Subject: [PATCH 2/2] ARM: at91/dt: sama5d2 Xplained: add regulators for sdhci devices
Date: Fri, 6 Nov 2015 16:59:30 +0100 [thread overview]
Message-ID: <1446825570-30029-3-git-send-email-ludovic.desroches@atmel.com> (raw)
In-Reply-To: <1446825570-30029-1-git-send-email-ludovic.desroches@atmel.com>
Add vmmc and vqmmc regulators for sdhci devices.
The voltage for sdmmc0 vqmmc is selected by a signal from coming from
the sdhci device.
