This patch series introduces support for Nuvoton NCT6694, a peripheral
expander based on USB interface. It models the chip as an MFD driver
(1/7), GPIO driver(2/7), I2C Adapter driver(3/7), CANfd driver(4/7),
WDT driver(5/7), HWMON driver(6/7), and RTC driver(7/7).
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 request interrupt 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
Changes since version 1:
- Implement IRQ domain to handle IRQ demux in nct6694.c
- Modify USB_DEVICE to USB_DEVICE_AND_INTERFACE_INFO API in nct6694.c
- Add each driver's command structure
- Fix USB functions in nct6694.c
- Fix platform driver registration in each child driver
- Sort each driver's header files alphabetically
- Drop unnecessary header in gpio-nct6694.c
- Add gpio line names in gpio-nct6694.c
- Fix errors and warnings in nct6694_canfd.c
- Fix TX-flow control in nct6694_canfd.c
- Fix warnings in nct6694_wdt.c
- Drop unnecessary logs in nct6694_wdt.c
- Modify start() function to setup device in nct6694_wdt.c
- Add voltage sensors functionality in nct6694-hwmon.c
- Add temperature sensors functionality in nct6694-hwmon.c
- Fix overwrite error return values in nct6694-hwmon.c
- Add write value limitation for each write() function in nct6694-hwmon.c
- Drop unnecessary logs in rtc-nct6694.c
- Fix overwrite error return values in rtc-nct6694.c
- Modify to use dev_err_probe API in rtc-nct6694.c
