[PATCH v4 0/7] pcal6524 extensions and fixes for pca953x driver

["H. Nikolaus Schaller" <hns@goldelico.com>]

V4:
* introduced PCA_LATCH_INT constant to make of_table more
  readable (suggested by Andy Shevchenko)
* converted all register constants to hex in a separate
  patch (suggested by Andy Shevchenko)
* separated additional pcal953x and pcal6524 register
  definitions into separate patches (suggested by Andy Shevchenko)
* made special pcal6524 address adjustment more readable
  (suggested by Andy Shevchenko)
* moved gpio-controller and interrupt-controller to the
  "required" section (reviewed by Rob Herring)

2018-04-10 18:07:07: V3:
* add Reported-by: and Reviewed-by:
* fix wording for bindings description and example
* convert all register offsets to hex
* omit the LEVEL-IRQ RFC/hack commit

2018-04-04 21:00:27: V2:
* added PCA_PCAL flags if matched through of-table
* fix address calculation for extended PCAL6524 registers
* hack to map LEVEL_LOW to EDGE_FALLING to be able to
  test in combination with ts3a227e driver
* improve description of bindings for optional vcc-supply
  and interrupt-controller;
