Date: Mon, 11 Jun 2007 15:53:37 +0800 From: Mark Zhan <rongkai.zhan@...driver.com> To: netdev@...r.kernel.org Cc: "linuxppc-dev@...abs.org" <linuxppc-dev@...abs.org>, Vitaly Bordug <vbordug@...mvista.com> Subject: [PATCH] MII bitbang driver should generate MII bus phy_mask dynamically Current MII bitbang bus driver hard-codes the phy mask of mii_bus to ~0x09, which is actually specific to the FSL boards. This patch will make the bitbang driver to generate MII bus phy_mask dynamically, by the PHY irq info provided by the platform.
