This patch series adds support for Diolan USB-I2C/GPIO Master Adapter DLN-2. Details about device can be found here: https://www.diolan.com/i2c/i2c_interface.html. Changes since v7: * MFD: add results parameter to dln2_transfer to allow receiving the hardware result code; also fix dln2_transfer to return error only if the result code is > 0x80; * GPIO: update to the new dln2_transfer API * I2C: update to the new dln2_transfer API, use DECLARE_BITMAP, use new_cb as a variable name instead of new, update the Kconfig help to mentioned DLN2_I2C and DLN2_GPIO, remove i2c_setup as it is not useful anymore after removing the frequency code Changes since v6: * MFD: make sure DLN2_HANDLE_EVENT stays 0, move a few operations out of the lock block, renamed one missed _rx_callback function to _event_callback, speed-up disconnect by checking for it in find_free_slot, remove the URB submit helper and simplify URB resubmit code, use mfd_add_hotplug_devices, change the driver name to dln2 (from usb-dln2), initialize disconnect_lock * GPIO: no changes * I2C: keep sorting in Kconfig and Makefile, add warning for transfers bigger then DLN2_I2C_MAX_XFER_SIZE, remove frequency code - I will send a separate patch that moves this to i2c core, revert to using tx structures for dln2_i2c_enable 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 | 557 +++++++++++++++++++++++++++++++ drivers/gpio/gpiolib.c | 2 +- drivers/i2c/busses/Kconfig | 10 + drivers/i2c/busses/Makefile | 1 + drivers/i2c/busses/i2c-dln2.c | 270 +++++++++++++++ drivers/mfd/Kconfig | 11 + drivers/mfd/Makefile | 1 + drivers/mfd/dln2.c | 756 ++++++++++++++++++++++++++++++++++++++++++ include/linux/gpio/driver.h | 3 + include/linux/mfd/dln2.h | 69 ++++ 12 files changed, 1692 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 -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
