Subject: [PATCH 2/3] ARM: dts: configure regulators for Gumstix Pepper
Date: Thu, 4 Jun 2015 11:08:18 -0700 [thread overview]
Message-ID: <1433441299-18887-3-git-send-email-arun@gumstix.com> (raw)
In-Reply-To: <1433441299-18887-1-git-send-email-arun@gumstix.com>
From: Adam YH Lee <adam.yh.lee@gmail.com>
Boot process is halting in midway because some of the necessary voltage
regulators are deemed unused and subsequently powered off, leading to
a completely unresponsive system.
Most of the device nodes had correct voltage regulator attachments.
Yet these nodes had to set stricter enforcement on them through
'regulator-boot-on' and 'regulator-always-on' to function correctly.
