Subject: [PATCH V3] ARM: dts: imx6sll-evk: make pfuze100 sw4 always on
Date: Wed, 27 Jun 2018 09:25:25 +0800	[thread overview]
Message-ID: <1530062725-25779-1-git-send-email-Anson.Huang@nxp.com> (raw)

On i.MX6SLL EVK board, PFuze100's SW4 is supplying
LPDDR3, it needs to be always on. This patch fixes
Linux kernel boot up hang caused by commit 5fe156f1cab4
("regulator: pfuze100: add enable/disable for switch"),
because SW4 is turned off unexpectedly:

[    1.693613] cfg80211: failed to load regulatory.db
[    1.700063] SW4: disabling
[    1.703973] SWBST: disabling

Fixes: 5fe156f1cab4 ("regulator: pfuze100: add enable/disable for switch")
