Subject: [PATCH v3 7/7] usb: mtu3: add optional clock xhci_ck and frmcnt_ck
Date: Mon, 17 Apr 2023 10:52:03 +0800 [thread overview]
Message-ID: <20230417025203.18097-7-chunfeng.yun@mediatek.com> (raw)
In-Reply-To: <20230417025203.18097-1-chunfeng.yun@mediatek.com>
Add optional clock 'xhci_ck' which is usually the same as sys_ck, but
some SoC use two separated clocks when the controller supports dual
role mode;
Add optional clock 'frmcnt_ck' used on 4nm or advanced process SoC.
