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 Ming Yu (9): mfd: Add core driver for Nuvoton NCT6694 gpio: Add Nuvoton NCT6694 GPIO support i2c: Add Nuvoton NCT6694 I2C support can: Add Nuvoton NCT6694 CAN support watchdog: Add Nuvoton NCT6694 WDT support hwmon: Add Nuvoton NCT6694 HWMON support iio: adc: Add Nuvoton NCT6694 IIO support pwm: Add Nuvoton NCT6694 PWM support rtc: Add Nuvoton NCT6694 RTC support MAINTAINERS | 15 + drivers/gpio/Kconfig | 12 + drivers/gpio/Makefile | 1 + drivers/gpio/gpio-nct6694.c | 489 ++++++++++++++++++ drivers/hwmon/Kconfig | 10 + drivers/hwmon/Makefile | 1 + drivers/hwmon/nct6694-hwmon.c | 407 +++++++++++++++ drivers/i2c/busses/Kconfig | 10 + drivers/i2c/busses/Makefile | 1 + drivers/i2c/busses/i2c-nct6694.c | 166 ++++++ drivers/iio/adc/Kconfig | 10 + drivers/iio/adc/Makefile | 1 + drivers/iio/adc/nct6694_adc.c | 616 ++++++++++++++++++++++ drivers/mfd/Kconfig | 10 + drivers/mfd/Makefile | 2 + drivers/mfd/nct6694.c | 394 +++++++++++++++ drivers/net/can/Kconfig | 10 + drivers/net/can/Makefile | 1 + drivers/net/can/nct6694_canfd.c | 843 +++++++++++++++++++++++++++++++ drivers/pwm/Kconfig | 10 + drivers/pwm/Makefile | 1 + drivers/pwm/pwm-nct6694.c | 245 +++++++++ drivers/rtc/Kconfig | 10 + drivers/rtc/Makefile | 1 + drivers/rtc/rtc-nct6694.c | 276 ++++++++++ drivers/watchdog/Kconfig | 11 + drivers/watchdog/Makefile | 1 + drivers/watchdog/nct6694_wdt.c | 329 ++++++++++++ include/linux/mfd/nct6694.h | 168 ++++++ 29 files changed, 4051 insertions(+) create mode 100644 drivers/gpio/gpio-nct6694.c create mode 100644 drivers/hwmon/nct6694-hwmon.c create mode 100644 drivers/i2c/busses/i2c-nct6694.c create mode 100644 drivers/iio/adc/nct6694_adc.c create mode 100644 drivers/mfd/nct6694.c create mode 100644 drivers/net/can/nct6694_canfd.c create mode 100644 drivers/pwm/pwm-nct6694.c create mode 100644 drivers/rtc/rtc-nct6694.c create mode 100644 drivers/watchdog/nct6694_wdt.c create mode 100644 include/linux/mfd/nct6694.h
