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;
