Subject: [PATCH v2] soc: add aspeed folder and misc drivers
From:   Patrick Venture <venture@google.com>
To:     venture@google.com, arnd@arndb.de, gregkh@linuxfoundation.org,
        joel@jms.id.au, andrew@aj.id.au
Cc:     linux-kernel@vger.kernel.org, linux-arm-kernel@lists.infradead.org,

Content-Type: text/plain; charset="UTF-8"
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Create a SoC folder for the ASPEED parts and place the misc drivers
currently present into this folder.  These drivers are not generic part
drivers, but rather only apply to the ASPEED SoCs.
