		Except for the oldest chips (VT82C596A/B, VT82C686A and most probably
		VT8231), this driver supports I2C block transactions. Such transactions
		are mainly useful to read from and write to EEPROMs.

		The CX700 additionally appears to support SMBus PEC, although this driver
		doesn't implement it yet.
