Subject: [PATCH 01/10] net: hisilicon: Add support for HI13X1 to hip04_eth
Date:   Fri, 5 Jul 2019 14:10:28 +0800
Message-ID: <1562307028-103555-1-git-send-email-xiaojiangfeng@huawei.com>
MIME-Version: 1.0
Content-Type: text/plain
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Extend the hip04_eth driver to support HI13X1_GMAC.
Enable it with CONFIG_HI13X1_GMAC option.

HI13X1 changed the offsets and bitmaps for registers
in the same peripheral device on different models of
the hip04_eth.
