      1* ST Keyscan controller Device Tree bindings
      2
      3The ST keyscan controller Device Tree binding is based on the
      4matrix-keymap.
      5
      6Required properties:
      7- compatible: "st,sti-keyscan"
      8
      9- reg: Register base address and size of st-keyscan controller.
     10
     11- interrupts: Interrupt number for the st-keyscan controller.
     12
     13- clocks: Must contain one entry, for the module clock.
     14  See ../clocks/clock-bindings.txt for details.
     15
     16- pinctrl: Should specify pin control groups used for this controller.
     17  See ../pinctrl/pinctrl-bindings.txt for details.
     18
     19- linux,keymap: The keymap for keys as described in the binding document
     20  devicetree/bindings/input/matrix-keymap.txt.
     21
     22- keypad,num-rows: Number of row lines connected to the keypad controller.
     23
     24- keypad,num-columns: Number of column lines connected to the keypad
     25  controller.
     26
     27Optional property:
     28- st,debounce_us: Debouncing interval time in microseconds
     29
