Subject: [PATCH v1 0/9] Add Nuvoton NCT6694 MFD devices

This patch series introduces support for Nuvoton NCT6694, a peripheral
expander based on USB interface. It models the chip as an MFD driver
(1/9), GPIO driver(2/9), I2C Adapter driver(3/9), CANfd driver(4/9),
WDT driver(5/9), HWMON driver(6/9), IIO driver(7/9), PWM driver(8/9),
and RTC driver(9/9).

The MFD driver implements USB device functionality to issue
custom-define USB bulk pipe packets for NCT6694. Each child device can
use the USB functions nct6694_read_msg() and nct6694_write_msg() to issue
a command. They can also register a handler function that will be called
when the USB device receives its interrupt pipe.

The following introduces the custom-define USB transactions:
	nct6694_read_msg - Send bulk-out pipe to write request packet
			   Receive bulk-in pipe to read response packet
			   Receive bulk-in pipe to read data packet

	nct6694_write_msg - Send bulk-out pipe to write request packet
			    Send bulk-out pipe to write data packet
                            Receive bulk-in pipe to read response packet
                            Receive bulk-in pipe to read data packet
