SGI IP22/IP28 machines have GIO busses for adding graphics and other extension cards. This patch adds support for GIO driver/device handling and converts the newport console driver to a GIO driver. [ralf@linux-mips.org: Fixed build error caused by the modules.h -> export.h changes.] Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de> Acked-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de> To: linux-fbdev@vger.kernel.org Patchwork: https://patchwork.linux-mips.org/patch/2886/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
