Subject: [PATCH v2 1/3] dt-bindings: soc: Add clocks for Mediatek SCPSYS unit
Date: Wed, 7 Oct 2015 17:14:39 +0800 [thread overview]
Message-ID: <1444209281-25536-2-git-send-email-jamesjj.liao@mediatek.com> (raw)
In-Reply-To: <1444209281-25536-1-git-send-email-jamesjj.liao@mediatek.com>
Add clocks needed by Mediatek VENC and VENC_LT power domianis.
These clocks were needed by accessing subsystem's registers,
so they need to be enabled before power on these subsystems.
