From mboxrd@z Thu Jan 1 00:00:00 1970 From: Yoshihiro Shimoda Date: Tue, 08 Mar 2011 07:59:55 +0000 Subject: [PATCH 6/6] net: sh_eth: add set_mdio_gate in bb_info Message-Id: <4D75E1FB.6000607@renesas.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: netdev@vger.kernel.org Cc: SH-Linux The SH7757's ETHER and GETHER use common MDIO pin. The MDIO pin is selected by specific register. So this patch adds new interface in bb_info, and when the sh_eth driver use the mdio, the register can be changed by the function.
