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.
