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. Reported-by: Alex Elder <elder@linaro.org> Signed-off-by: Matt Porter <mporter@linaro.org> Tested-by: Alex Elder <elder@linaro.org>
