Details about device can be found here: https://www.diolan.com/i2c/i2c_interface.html. Changes since v4: * Add a new gpiolib chip flag to allow blocking chips with non threaded IRQ handlers * MFD: set GPLv2 as license, fix a couple of coding style issues, add code to stop I/O after USB disconnect and prevent further I/O, simplify the DNL2 platform data * GPIO: add modalias, set GPLv2 as license, rework pin direction caching, use irq_find_mapping in dln2_irq_unmask, allocate irq work based on the number of pins read from the device, flush irq work at remove time, use RCU to iterate and run the callback list * I2C: add modalias, set GPLv2 as license, allocate the RX/TX buf separately to avoid cache line sharing issue, don't truncate i2c reads, use u32 instead of uint32_t, attach the sysfs freq attribute to the i2c adapter device instead of the platform device (and also use device attribute groups), simplify dln2_i2c_read a bit Daniel Baluta (1): gpio: add support for the Diolan DLN-2 USB GPIO driver Laurentiu Palcu (1): i2c: add support for Diolan DLN-2 USB-I2C adapter Octavian Purdila (2): mfd: add support for Diolan DLN-2 devices gpiolib: add irq_not_threaded flag to gpio_chip drivers/gpio/Kconfig | 12 + drivers/gpio/Makefile | 1 + drivers/gpio/gpio-dln2.c | 554 ++++++++++++++++++++++++++++++ drivers/gpio/gpiolib.c | 2 +- drivers/i2c/busses/Kconfig | 10 + drivers/i2c/busses/Makefile | 1 + drivers/i2c/busses/i2c-dln2.c | 383 +++++++++++++++++++++ drivers/mfd/Kconfig | 9 + drivers/mfd/Makefile | 1 + drivers/mfd/dln2.c | 758 ++++++++++++++++++++++++++++++++++++++++++ include/linux/gpio/driver.h | 3 + include/linux/mfd/dln2.h | 67 ++++ 12 files changed, 1800 insertions(+), 1 deletion(-) create mode 100644 drivers/gpio/gpio-dln2.c create mode 100644 drivers/i2c/busses/i2c-dln2.c create mode 100644 drivers/mfd/dln2.c create mode 100644 include/linux/mfd/dln2.h -- 1.9.1
