From: Patrice Chotard Date: Mon, 26 Aug 2019 11:50:31 +0000 (+0200) Subject: regulator: fixed: Modify enable-active-high behavior X-Git-Tag: v2020.01-rc1~28^2~11 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=e8e9715df2d4;p=oweals%2Fu-boot.git regulator: fixed: Modify enable-active-high behavior Regulator should not be enabled at probe time if regulator-boot-on property is not in the dt node. "enable-active-high" property is only used to indicate the GPIO polarity.
