Subject: [PATCH] ARM: dts: bcm28155-ap: leave camldo1 on to fix reboot
Date: Wed, 12 Mar 2014 09:14:39 -0400 [thread overview]
Message-ID: <1394630079-12063-1-git-send-email-mporter@linaro.org> (raw)
The BCM28155-AP board has a bootloader that expects the camldo1
regulator to be enabled on entry. Currently, the camldo1 regulator
is disabled when no longer in use as is the case during a reboot /
warm reset. This causes the early bootloader to hang upon entry. Add
regulator-always-on to the camldo1 constraint to fix reboot.
