From 2b17d2f8bc55e0abe5f03fda065d73cfcf465e5c Mon Sep 17 00:00:00 2001 From: Andi Shyti Date: Fri, 10 Feb 2017 11:17:21 +0900 Subject: [PATCH] arm64: dts: exynos: Add stmfts touchscreen node for TM2 and TM2E TM2 and TM2E devices are provided with a ST-Microelectronics Finger Tip S device with small differences: - screen size - TM2E uses the stmfts also as a touchkey for "back" and "menu" In this commit the initial value of the interrupt line is set to EXYNOS_PIN_PULL_UP as the interrupt is triggered when the line goes down.
