Subject: ARM: dts: at91: sama5d4 Xplained: don't disable hsmci regulator
From: Ludovic Desroches <ludovic.desroches@xxxxxxxxx>
commit b02acd4e62602a6ab307da84388a16bf60106c48 upstream.
If enabling the hsmci regulator on card detection, the board can reboot
on sd card insertion. Keeping the regulator always enabled fixes this
issue.
