Subject: [PATCH v8 0/4] mfd: add support for Diolan DLN-2

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
