Subject[PATCH] ARM: dts: bcm28155-ap: leave camldo1 on to fix reboot
Date
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.
