This adds device tree bindings for the Hycon HY46XX touchscreen series. Signed-off-by: Giulio Benetti <giulio.benetti@benettiengineering.com> --- V1->V2: As suggested by Rob Herring: * fixed $id: address * added "hycon," in front of every custom property * changed all possible property to boolean type * removed proximity-sensor-switch property since it's not handled in driver V2->V3: As suggested by Jonathan Neuschäfer: * fixed some typo * fixed description indentation * improved boolean properties descriptions * improved hycon,report-speed description V3->V4: * fixed binding compatible string in example as suggested by Jonathan Neuschäfer V4->V5: As suggested by Rob Herring: * drop hycon- prefix from compatible * use Hertz unit suffix for hycon,report-speed instead of u32 * set hycon,report-speed minimum to 1Hz, 0Hz make controller to do nothing * change hycon,power-noise-enable property name to hycon,noise-filter-enable * improve hycon,filter-data property description * use generic touchscreen node name in example V5->V6: * changed report-speed property name into report-speed-hz according to Rob Herring's suggestion --- .../input/touchscreen/hycon,hy46xx.yaml | 119 ++++++++++++++++++ MAINTAINERS | 6 + 2 files changed, 125 insertions(+) create mode 100644 Documentation/devicetree/bindings/input/touchscreen/hycon,hy46xx.yaml
