Subject: [PATCH V2 10/15] cpufreq: mediatek: Make sram regulator optional
Date: Fri, 8 Apr 2022 12:59:03 +0800 [thread overview]
Message-ID: <20220408045908.21671-11-rex-bc.chen@mediatek.com> (raw)
In-Reply-To: <20220408045908.21671-1-rex-bc.chen@mediatek.com>
From: Jia-Wei Chang <jia-wei.chang@mediatek.com>
For some MediaTek SoCs, like MT8186, it's possible that the sram regulator
is shared between CPU and CCI.
