If anyone has any objections, please let me know. ------------------ From: Konrad Dybcio [ Upstream commit 85e985a4f46e462a37f1875cb74ed380e7c0c2e0 ] The CO0 BCM needs to be up at all times, otherwise some hardware (like the UFS controller) loses its connection to the rest of the SoC, resulting in a hang of the platform, accompanied by a spectacular logspam. Mark it as keepalive to prevent such cases.
