From 16aced80f6739beb2a6ff7b6f96c83ba80d331e8 Mon Sep 17 00:00:00 2001 From: Zumeng Chen Date: Wed, 20 Jun 2012 17:14:53 +0800 Subject: ARM: OMAP3530evm: set pendown_state and debounce time for ads7846 Currently most ads7846 config definitions for OMAP3 series boards have been moved to common-board-devices.c, and it is transparent for init. And it's no very proper to do gpio_request based on get_pendown_state since omap_ads7846_init knows everything about ads7846_config. So it's more fit to request gpio according to the right gpio_pendown and set debounce time conditionally. If we don't set proper debouce time, there are flooded interrupt counters of ads7846 responding to one time touch on screen, then the driver couldn't work very well. This patch has been validated on 3530evm.
