The TCA8418 might be used using different interrupt triggers on various boards. This is not working so far because the current code forces a falling edge trigger. The device tree already provides a trigger type, so let's use whatever it sets up, and since we can be loaded without DT, keep the old behaviour for the non-DT case. Signed-off-by: Maxime Ripard <redacted> --- Hi, This is the second version of the patch "drivers: tca8418: Change the interrupt type" that was sent initially on 14/11, and didn't get any answer. Changes from v1: - Rely on the trigger type provided by the DT drivers/input/keyboard/tca8418_keypad.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-)
