Date: Sat, 25 Jul 2020 11:51:56 +0800 Message-Id: <20200725035159.31231-3-zhouyanjie@wanyeetech.com> X-Mailer: git-send-email 2.11.0 In-Reply-To: <20200725035159.31231-1-zhouyanjie@wanyeetech.com> References: <20200725035159.31231-1-zhouyanjie@wanyeetech.com> MIME-Version: 1.0 Sender: linux-usb-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: linux-usb@vger.kernel.org 1.Modify the macro definition to unify "#define USBPCR_XXXX n" into the "#define USBPCR_XXXX (n << USBPCR_XXXX_LSB)" style, so as to unify the code style in the "jz4770_phy_init()" and simplify the code. 2.Remove unused macro definitions to simplify the code.
