Subject: [PATCH] ARM: at91/dt: sama5d3 xplained: don't disable hsmci regulator
Date: Fri, 11 Mar 2016 11:43:39 +0100 [thread overview]
Message-ID: <1457693033-3619-1-git-send-email-ludovic.desroches@atmel.com> (raw)
If enabling the hsmci regulator on card detection, the board can reboot
on sd card insertion. Keeping the regulator always enabled fixes this
issue.
Signed-off-by: Ludovic Desroches <ludovic.desroches@atmel.com>
Fixes: 1b53e3416dd0 ("ARM: at91/dt: sama5d3 xplained: add fixed
regulator for vmmc0")
Cc: stable@vger.kernel.org #4.3 and later
