From 5dc15dcf39c40fcc420e41b43e31ab260c3feec3 Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Fri, 9 Aug 2019 09:48:51 -0700 Subject: [PATCH] ARM: ux500: improve BU21013 touchpad bindings In preparation to update to bu21013_tp driver properly annotate GPIOs property (the INT GPIOs are active low, not open drain), and also define interrupt lines so we do not have to have special conversion in the driver.
