+title: Generic Parallel-in/Serial-out Shift Register GPIO Driver
+
+description:
+ This binding describes generic parallel-in/serial-out shift register
+ devices that can be used for GPI (General Purpose Input). This includes
+ SN74165 serial-out shift registers and the SN65HVS88x series of
+ industrial serializers.
