Subject: [PATCH] ARM: at91/dt: add always-on to 1.8V regulator
Date: Wed, 2 Dec 2015 11:06:40 +0100 [thread overview]
Message-ID: <1449050800-29284-1-git-send-email-nicolas.ferre@atmel.com> (raw)
As the SDHCI controller needs the 1.8V line to be always enabled for some eMMC
configurations, set the proper "regulator-always-on" property to the board DTS
files.
Note that the sdhci classical regulator definitions doesn't suit our controller
for this 1.8V purpose.
