void ps3_vuart_clear_rx_bytes	(	struct ps3_system_bus_device *	dev,
		unsigned int	bytes
	)

ps3_vuart_clear_rx_bytes - Discard bytes received. : The struct ps3_system_bus_device instance. : Max byte count to discard, zero = all pending.

Used to clear pending rx interrupt source. Will not block.

int ps3_vuart_read	(	struct ps3_system_bus_device *	dev,
		void *	buf,
		unsigned int	bytes
	)

ps3_vuart_read - The entry point for reading data from a port.

Queue data waiting at the port, and if enough bytes to satisfy the request are held in the buffer list those bytes are dequeued and copied to the caller's buffer. Emptied list buffers are retiered. If the request cannot be statified by bytes held in the list buffers -EAGAIN is returned.

int ps3_vuart_write	(	struct ps3_system_bus_device *	dev,
		const void *	buf,
		unsigned int	bytes
	)

ps3_vuart_write - the entry point for writing data to a port : The struct ps3_system_bus_device instance.

If the port is idle on entry as much of the incoming data is written to the port as the port will accept. Otherwise a list buffer is created and any remaning incoming data is copied to that buffer. The buffer is then enqueued for transmision via the transmit interrupt.
