Basic support for the GPIO available on the SBC610 VPX Single Board Computer from GE Fanuc (PowerPC MPC8641D). This patch adds basic support for the GPIO in the devices I/O FPGA, the GPIO functionality is exposed through the AFIX pins on the backplane, unless used by an AFIX card. This code currently does not support switching between totem-pole and open-drain outputs (when used as outputs, GPIOs default to totem-pole). The interrupt capabilites of the GPIO lines is also not currently supported. Signed-off-by: Martyn Welch <martyn.welch@gefanuc.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org> |
