We had introduced the QUP-CORE ICC path to put proxy votes from QUP wrapper on behalf of earlycon, if other users of QUP-CORE turn off this clock before the real console is probed, unclocked access to HW was seen from earlycon. With ICC sync state support proxy votes are no longer need as ICC will ensure that the default bootloader votes are not removed until all it's consumer are probed. We can safely remove ICC path for QUP-CORE clock from QUP wrapper device. Signed-off-by: Roja Rani Yarubandi <redacted> Signed-off-by: Akash Asthana <redacted>
