Dmitriy Sharikhin 4cbb1513a2 hw/gpio: introduce pcf8574 driver ... NXP PCF8574 and compatible ICs are simple I2C GPIO expanders. PCF8574 incorporates quasi-bidirectional IO, and simple communication protocol, when IO read is I2C byte read, and IO write is I2C byte write. User can think of it as open-drain port, when line high state is input and line low state is output.
