Subject: [PATCH v5 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 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
