Subject:    [PATCH 2/3] ARM: OMAP: DRA7: powerdomain data: Fix "ON" state for memories
From:       Nishanth Menon <nm () ti ! com>
Date:       2016-03-31 21:58:34
Message-ID: 1459461515-5192-3-git-send-email-nm () ti ! com
[Download RAW message or body]

When the power domain is in "ON" state, the memories should be always
in "ON", even though the hardware register allows other states to be
written, wrong states may confuse certain hardware blocks.
