2021-10-22dt-bindings: auxdisplay: ht16k33: Document LED subnodeGeert Uytterhoeven1-0/+12
Extend the Holtek HT16K33 LED controller Device Tree bindings with an LED subnode, conforming to the standard LED bindings. This allows the user to exert more control, like specifying LED color, function, and/or trigger, to extend LED functionality beyond a simple display backlight.

2021-10-22dt-bindings: auxdisplay: ht16k33: Document Adafruit segment displaysGeert Uytterhoeven1-3/+17
The Holtek HT16K33 LED controller is not only used for driving dot-matrix displays, but also for driving segment displays. Document compatible values for the Adafruit 7-segment[1] and 14-segment[2] FeatherWing expansion boards with red displays. According to the schematics, all other Adafruit 7-segment and 14-segment display backpack and FeatherWing expansion boards (including bare boards and boards fitted with displays) are compatible with these two boards.

2017-04-08auxdisplay: hd44780: Fix DT properties to include units of measurementGeert Uytterhoeven1-5/+6
DT properties specifying physical properties should contain appropriate suffices indicating the units of measurement. Hence amend the HD44780 DT bindings to add "chars" suffixes to the "display-height" and "display-width" properties, and update the driver to parse them.
