+Altera FPGAs in passive serial mode
+-----------------------------------
+
+This binding defines the control interface to Altera FPGAs in
+passive serial mode. This is used to upload the firmware and
+to start the FPGA.
+
+Required properties:
+- compatible: shall be "altr,passive-serial"
+- reg: SPI chip select
+- nstat-gpio: Specify GPIO for controlling the nstat pin
+- confd-gpio: Specify GPIO for controlling the confd pin
+- nconfig-gpio: Specify GPIO for controlling the nconfig pin
