Subject: [PATCH V6 5/8] clk: mediatek: add MUX_GATE_FLAGS_2
Date: Mon, 25 Feb 2019 10:09:09 +0800 [thread overview]
Message-ID: <20190225020912.29120-6-wangyan.wang@mediatek.com> (raw)
In-Reply-To: <20190225020912.29120-1-wangyan.wang@mediatek.com>
From: chunhui dai <chunhui.dai@mediatek.com>
Add MUX_GATE_FLAGS_2 for the clock which needs to set two falgs.
Such as some mux need to set the flags of "CLK_MUX_ROUND_CLOSEST".
