Subject: [PATCH v3 07/12] clk: mediatek: Add flags support for mtk_gate data
Date: Mon, 10 Dec 2018 15:32:35 +0800 [thread overview]
Message-ID: <20181210073240.32278-9-weiyi.lu@mediatek.com> (raw)
In-Reply-To: <20181210073240.32278-1-weiyi.lu@mediatek.com>
On some Mediatek platforms, there are critical clocks of
clock gate type.
To register clock gate with flags CLK_IS_CRITICAL,
we need to add the flags field in mtk_gate data and register APIs.
