I searched at drivers/input and Documents.
Two drivers use "debounce-interval", gpio-keys.c and stmpe-keypad.c.
They describe the meanings of "debounce-interval" at its own document file.
Some other drivers uses "xxx,debounce-delay-ms" or "debounce-delay-ms"
So it seems that there is no generic prop name for this debounce interval.
