Date: Sat, 12 Sep 2015 10:45:50 -0700 From: Dmitry Torokhov <dmitry.torokhov@...il.com> To: linux-input@...r.kernel.org Cc: linux-kernel@...r.kernel.org, Franklin S Cooper Jr <fcooper@...com>, Maxime Ripard <maxime.ripard@...e-electrons.com>, Lothar Waßmann <LW@...O-electronics.de> Subject: [PATCH 5/6] Input: edt-ft5x06 - do not hardcode interrupt trigger type Instead of hardcoding IRQ trigger type to IRQF_TRIGGER_FALLING, let's respect settings specified in device tree. To be compatible with older DTSes, if trigger type is not set up in DTS we'll set it to default (falling edge).
