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 Ming Yu (7): 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 rtc: Add Nuvoton NCT6694 RTC support MAINTAINERS | 13 + drivers/gpio/Kconfig | 12 + drivers/gpio/Makefile | 1 + drivers/gpio/gpio-nct6694.c | 441 +++++++++++++++ drivers/hwmon/Kconfig | 10 + drivers/hwmon/Makefile | 1 + drivers/hwmon/nct6694-hwmon.c | 771 +++++++++++++++++++++++++ drivers/i2c/busses/Kconfig | 10 + drivers/i2c/busses/Makefile | 1 + drivers/i2c/busses/i2c-nct6694.c | 152 +++++ drivers/mfd/Kconfig | 10 + drivers/mfd/Makefile | 2 + drivers/mfd/nct6694.c | 382 +++++++++++++ drivers/net/can/Kconfig | 10 + drivers/net/can/Makefile | 1 + drivers/net/can/nct6694_canfd.c | 926 +++++++++++++++++++++++++++++++ drivers/rtc/Kconfig | 10 + drivers/rtc/Makefile | 1 + drivers/rtc/rtc-nct6694.c | 263 +++++++++ drivers/watchdog/Kconfig | 11 + drivers/watchdog/Makefile | 1 + drivers/watchdog/nct6694_wdt.c | 277 +++++++++ include/linux/mfd/nct6694.h | 139 +++++ 23 files changed, 3445 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/mfd/nct6694.c create mode 100644 drivers/net/can/nct6694_canfd.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
