[PATCH v6 0/4] mfd: add support for Diolan DLN-2

[Octavian Purdila <octavian.purdila@xxxxxxxxx>]

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 v5:

* MFD: use enum for handles, fix a couple of miss spells, rename a few
  fields for clarity, rework the disconnect mechanism, fix a couple of
  missing newlines in printks, use straight list_for_each instead of
  RCU versions in the update sides, used busnum << 8 | devnum as id in
  mfd_add_devices()

* GPIO: renamed pin_dir to output_enabled, disable GPIO if we failed
  getting the direction, don't set platform's driver owner field

* I2C: update Documentation/ABI for the added sysfs attributed, stored
  the port number in the dln2_i2c structure, used a temporary pointer
  to the tx/rx struct for readability, don't set platform's driver
  owner field
