Subject: [PATCHv3 0/4] Wiegand bus driver and GPIO bitbanged controller

Hello,

thank you for the feedback regarding last patch. I have decided against
using a copyright line despite the suggestion.

CHANGELOG since PATCHv2:
- dropped the Wiegand controller example from the dt-bindings doc, as
  the real one is in the bitbanged controller schema
- fixed some indentation issues
- removed controller class
- functions with "__" as prefix are no longer exported
- improved comment style
- fixed the line length of the code to 100 columns
- removed dev_warn calls for uinitialized controller attributes, instead
  the driver informs about the situation using dev_info and sets the
  uninitialized attribute to its default value
- removed modalias from wiegand_device structure, as I have realized it
  is no longer needed
- removed the list from wiegand_controller structure
- used the tool "pahole" to optimally reorganize all the structures
- ordered headers alphabetically
- removed unnecessary casts
- used attribute group instead of creating the files automatically

Martin Zaťovič (4):
  dt-bindings: wiegand: add Wiegand controller common properties
  wiegand: add Wiegand bus driver
  dt-bindings: wiegand: add GPIO bitbanged Wiegand controller
  wiegand: add Wiegand GPIO bitbanged controller driver
